The “Mars Monkey” and the articles of that time are still on display at the museum of the Georgia State Bureau of Investigation. However, that night was different. They saw a strange creature, seemingly a dead alien… The incident was shocking, but the truth later made the public even more surprised. Strange creatures cause panic “Mars Monkey” once caused panic in Atlanta, Georgia, USA. On July 8, 1953, Sherley Brown and her teammates drove along the Bankhead Highway outside the town of Austell, Georgia, USA, patrolling as usual. When they came to a bend, they had to stop because a pickup truck stopped in the middle of the road, next to them were three men looking very excited and scared. When Brown got out of the car to find out what had happened, he learned it was two barbers named Ed Watters and Tom Wilson, and the other had a butcher’s shop named Arnold Payne. All three live in the town of Austell. They were excited, arguing with each other. After being reassured, they reported the incident. It turned out that this was not a murder as the two police officers initially thought. They said, while driving along a quiet country road and turning a bend, they saw a bright red flying saucer hovering over the asphalt. When they slowed down to take a closer look, they were surprised to see two strange creatures about 60 cm tall lurking in the bushes, then one rushed out in front of their truck and was hit, while the other one rushes onto the swooping flying object. The flying saucer then emitted a blue light and sped away into the night, shooting flames that blazed across the pavement. They also testified that when they stopped the car, they saw the strange creature lying dead on the road. Brown didn’t believe this, until they showed him evidence that the highway pavement was indeed melted to a very high temperature and still had a strange creature on it. Brown noticed that the animal had no hair, pale body, contorted head and large round eyes. It looked disgusting and clearly out of this world, so Brown was forced to admit the three were telling the truth and immediately report the incident to headquarters. It didn’t take long for the story of UFOs and alien corpses to go viral. Soon after the police headquarters was reported, the Air Force and dozens of others claimed to have seen lights in the sky and strange creatures running back and forth that night. When the incident made headlines the next day with many images of the dead creature, many believed that there was an actual alien invasion. A local veterinarian, after examining the body of the strange creature, declared it “out of this world”, causing further panic among the public. The work of jokers The “Mars Monkey” and the articles published at the time are now on display at the museum of the Georgia State Bureau of Investigation. Not long after, the creature known as the “Mars monkey” was brought to Emory University, Atlanta to be examined by Dr. Herman Jones and Dr. Marion Hines, two professors of anatomy. And the result caused a stir in public opinion. It turns out that this is not a “Mars monkey” or an alien creature, but just an ordinary monkey, a rhesus monkey to be exact, which has been shaved and colorfully embellished to look. monstrous compared to reality. Three men who claimed to have run over the aliens then confessed that it was all a joke but didn’t expect it to get out of control. Accordingly, after stumbling upon a dead monkey, they brought it home to shave and cut off its tail, and then paint it with some green food coloring to increase the strangeness. After being satisfied with the “work”, they took it to the highway and used a torch to burn the asphalt to create circles like a melted UFO track. Even after these confessions were made public, it took a while for people to calm down and accept that they were tricked and that no aliens invaded. Meanwhile, the three jokers mentioned above were only convicted by the court of dumping animal carcasses causing unsanitary and obstructing highways, forcing them to pay a fine of 40 USD. After the trial, letters rushed to the local newspapers, demanding that these people be prosecuted before the law for cruelty to animals. Some even suggested shaving the head of the mastermind. However, a reader in Jacksonville, Florida wrote: “Don’t be too hard on these boys. They have done a meaningful job by making many people realize that they are still living in dark times of superstition and believing in unrealistic things.” Others said that the above incident proves that hoaxes with the inadvertent help of the media sometimes create an uproar. This happens all the time even in modern times, forcing us to stay awake and see strange things with the eyes of a difficult person. The incident that caused panic eventually subsided, and the “Mars monkey” was later owned by a small museum of the Georgia Bureau of Investigation, where it was displayed along with articles published in August. at that moment.

In the past, all three planets were rocky planets, the surface of which was composed of solid metals and silicates. Among them, our Earth is the largest planet, the mass and radius of Venus is only about 82% and 95% of the Earth, respectively, the mass and radius of Mars only account for about 11% and 53% when compared to our planet. Over the past few decades, humans have launched many unmanned probes to Venus and Mars, and it turns out that the environments on these two planets are very harsh. Venus is too hot, and Mars is too cold, and there is no oxygen on either planet, so life on Earth could not exist in such an environment, and astronomers could not find it. see any other traces of life there. So, how were Venus and Mars 4 billion years ago? Why are Venus and Mars now barren, and only our planet is habitable? Calculated based on the radiant power of the sun, Venus and Mars also operate in the same habitable zone as Earth, which means they can receive just the right amount of solar radiation to water. on their surface can still be in a liquid state. Astronomers speculate based on current signs on Venus and Mars and surmise that there may have been an ocean of liquid water on both Venus and Mars 4 billion years ago. For the first few hundred million years, Venus was a warm and humid planet. In the primordial oceans of Venus, life was fully qualified to evolve. They could be carbon-based life like life on Earth or could be other life forms. However, Venus’s habitable period did not last long. Because Venus is so close to the sun, and the temperature of the sun gradually increases over time, making Venus hotter and hotter, and a large amount of liquid water has also been evaporated. At the same time, the volcanic activity on Venus is also gradually becoming more active and continuously releasing carbon dioxide, causing a strong greenhouse effect. Without oceans, carbon dioxide would not be neutralized. They enter the atmosphere and cause a severe greenhouse effect, which will increase the temperature on Venus. Meanwhile, on Earth, the oceans, plants and minerals absorb large amounts of carbon dioxide, so the Earth will not become too hot due to the strong greenhouse effect during that period. Eventually, Venus’ greenhouse effect was completely out of control, liquid water completely evaporated, and life could have been destroyed. According to data returned by the Venus probe, the current concentration of carbon dioxide in Venus’s atmosphere is as high as 96.5%, and the surface atmospheric pressure is 91 times higher than the Earth’s surface. Under the influence of this extreme greenhouse effect, Venus has essentially reached thermal equilibrium, and the average surface temperature is as high as 464 degrees Celsius. Although it is essentially impossible to have life on the surface of Venus today, some astronomers speculate that there may be some strange life in the atmosphere of Venus. In the sky high enough above the surface of Venus, the atmospheric pressure will be moderate, and the temperature will not be high, possibly for the synthesis of organic matter and the evolution of life. On the other hand, ancient Mars was probably also a habitable planet. Currently, on Mars there is a large amount of water-washed terrain, and there are some iron ores that can only be generated in the aquatic environment, which is strong evidence for the existence of a large amount of water. liquid water on ancient Mars. So, how did Mars become such a uninhabitable planet as it is? At present-day Mars’ North Pole, there is a giant basin whose surface is equivalent to two-fifths of the surface of Mars. This huge Arctic basin was formed by a massive collision. Studies have shown that about 3.9 billion years ago, a dwarf planet (about the size of Pluto) with a diameter of about 2,000 km collided with the north pole of Mars. This massive collision completely changed the core of Mars, causing activities inside Mars to quickly stop, and the Martian magnetic field also gradually weakened and finally almost disappeared. lost. Without the protection of the magnetic field, the solar wind gradually strengthens and melts the atmosphere of Mars, liquid water continues to evaporate, causing Mars to quickly become a barren land. Currently, there is almost no atmosphere on Mars, but there is still some water ice in the polar regions. In addition, there may be a seasonal amount of liquid water in some areas of Mars, which has a high salt content and may be temporarily liquid in the low-temperature Martian environment. At the moment, the temperature on Mars is very low, the average temperature is only -63 degrees Celsius. If humans want to settle on Mars in the future, the first thing to do is to strengthen the star’s magnetic field. Mars and produces large amounts of greenhouse gases to “heat” Mars and melt the solid water that exists on Mars. Mars is much smaller than Earth, so it would have cooled from its molten state at its inception faster than Earth, so liquid water on Mars may have appeared earlier, which could This means that life on Mars may have formed and evolved earlier than our planet. Therefore, there are conspiracy theories that, when celestial bodies collided with Mars, the rocks that were thrown into space by the collisions could have carried the germ of life on Mars into space, and then some someday fall to Earth, becoming the source of life on Earth. And perhaps by coincidence, life on Earth also began to form around the same time that Mars’ North Pole collided. From the point of view of time, this is consistent. In addition, astronomers have discovered traces of suspected life in meteorites on Mars that have fallen to Earth. Life on Earth may have originated on Mars, but this has so far required more convincing evidence. In the past, the Curiosity rover has detected some carbon-containing organic substances in the rocks on Mars, which may be evidence that ancient Mars once had a few living things. Even now, it is still possible for life on Mars, they did not go extinct billions of years ago, but moved into the Martian underground and developed a unique survival mechanism to adapt to the harsh environment. harsh on this planet. Compared to Venus and Mars, our planet is very lucky. For billions of years, Earth has always been a habitable planet, so hundreds of millions of species have appeared here. Our Earth is like a “chosen planet”, a moderate distance from the sun, with a magnetic field that can resist solar radiation so that all kinds of life can continue to multiply and develop. Although it cannot be ruled out that some planets in the solar system (such as Europa) also harbor life, the environments of those planets are very different from those of Earth, and most life on Earth is not ruled out. Soil cannot exist there. In the near future, Earth will still be the only planet inhabited by humans in the universe.

The research results were published in the international academic journal “Science Advances” on June 11. The discovery is the result of a six-year experiment. In the experiment, the scientists stored freeze-dried mouse sperm on the International Space Station (ISS) and exposed them to radiation.

Healthy offspring from freeze-dried mouse sperm stored on the International Space Station

Researchers once thought that radiation in space would damage the DNA in cells, and may inherit mutations in future generations, making reproduction impossible. Cancer caused by radiation is another worrying issue.

Sayaka Wakayama, a member of the research team and a scholar at Yamanashi University in Japan, said that the lack of freezers on the International Space Station hindered long-term research on living cells. Moreover, even the current NASA space radiation cancer risk model is based on data from Hiroshima and Nagasaki atomic bomb survivors, “not from real space experiments.”

To overcome these limitations, the researchers freeze-dried sperm samples from 12 mice, sealed them in small capsules, and transported them to the International Space Station by rocket without the need for a freezer.

“Unlike the Earth’s surface, there are many different types of radiation in space. For example, heavy ions, protons, and electromagnetic waves from solar flares,” Wakayama explained. “It is very difficult to irradiate and replicate all these types of radiation on the ground at the same time. , So I think DNA damage in biological samples can only be measured in space.”

Schematic diagram of freeze-dried sperm preparation and the types of experiments performed

Scientists regularly test a small number of samples, send some of them back to Earth after 9 months, and leave the other two batches on the International Space Station for 2 years and 9 months and 5 years and 10 months respectively. After testing, the researchers found that freeze-dried sperm stored on the International Space Station for a long time did not cause DNA damage.

Studies have pointed out that when rehydrated sperm cells are injected into fresh ovarian cells and transferred to female mice, “healthy space pups” will be born.

The researchers said that although X-rays and space radiation damage DNA differently, it is roughly predicted that freeze-dried sperm “can be stored on the International Space Station for more than 200 years without causing damage to DNA.”

A total of 168 pups were born from sperm stored in space for 6 years. Compared with control mice born from sperm preserved on Earth, these “space pups” have normal appearance and genetic activity. mode.

Scientists believe that more studies from similar airborne experiments can reveal the effects of radiation and the tolerance of life forms that stay in space for a long time.

The Mars rover is roaming on Mars

These discoveries are crucial for mankind to enter the space age. At present, Mars probes from the United States and China are roaming on Mars, trying to find signs of life. In the future, there are plans for manned missions to Mars.

Mars hides the secret of life, always urging people to explore. Photo: NASA Today’s Earthlings are perhaps the most curious generation about the possibility of alien life on Mars, and are always wondering how humans might one day colonize there. From theories about Martian canals to alien radio messages, over the past three centuries, mankind has been constantly thinking about life on Mars. approach to his Martian “brothers”. Mars often appears in ancient texts as a “fire star,” or represents the god of War. In the 17th century, new early telescopes allowed scientists to get a glimpse of the Red Planet. Skilled “channel engineers”? Scientists need more powerful telescopes to be able to see up close, thereby trying to better clarify the hypothesis of life on Mars. In 1877, Italian astronomer Giovanni Schiaparelli noticed crisscrossing lines covering the “Red Planet”. He called these lines “canali”, which means “canal”. Schiaparelli himself does not believe that this is an alien product, but some others are sure of it. Giovanni Schiaparelli’s map of the “canal” system on Mars. Image: Wikimedia Commons As information spread, the word “canali” was translated into English as “canal”, meaning “canal”. And if there were canals, wouldn’t that suggest that aliens would have to dig them? With that argument, many people believe that the interlaced lines on the surface of Mars are a beautiful system of waterways spreading across the planet.. Such a system not only shows that Martians exist, but that they are also amazing engineers. On Earth, it took man 10 years to complete the Suez Canal in 1869. The achievements of the Martians therefore seem to be far superior to those achieved by man. Astronomer Percival Lowell certainly thought so. In 1894, this American scientist-businessman began to expand the concept of a “canal” on Mars. Lowell used his family’s large textile fortune to open the Lowell Observatory in Flagstaff, Arizona, USA. Professor Percival Lowell works with a telescope invested by his family. Image: Wikimedia Commons Percival Lowell mapped the “canals” on Mars with the help of the 24-inch Alvan Clark & ​​Sons refracting telescope he set up at the Lowell Observatory. He made meticulous maps of what was observed on the surface of Mars, wrote many books and regularly gave lectures on his shocking theory that Martians existed and that they were trying to irrigate the planet. their dying elf. Percival Lowell offers logical explanations to answer the question of how and why life exists on Mars. He used the example of life on Earth to illustrate his arguments: “As long as it was proved with certainty that no life could exist on the seabed, dredgers deep sea beds were invented, and before long, they ‘frustrated’ us. Behold, they see full of life. Fish, crustaceans, molluscs and echinoderms. In short, the life of all common floating fish, from protozoa to marine ‘monsters’ – have been found living in the depths of the seabed. What is impossible, turns out to be possible.” But mapping Mars is one thing, and soon scientists are looking for ways to make contact with any life that might exist on the planet. “Message” from the Red Planet In 1899, Lowell’s theory of life on Mars received a “kick” from a prominent scientist: Nikola Tesla. Tesla, then a successful electrical engineer, claimed that he had detected an “inexplicable, faint” signal originating from Mars. Portrait of Nikola Tesla circa 1890. Photo: Wikimedia Commons While conducting experiments with his magnifier at high latitudes atop Pike Peak, Colorado Springs, Tesla claimed that he received “a message from another world, unknown and far away. “. What does that message say? According to Nikola Tesla, it is simply: “ONE – TWO – THREE”. A few years later, on a February 1901 day, in an interview with Collier’s Weekly, inventor Tesla announced that he could communicate with Martians by sending wireless messages to any point. on the “Red Planet”. This is a strange statement, because the successful transmission of radio messages on Earth has only become a reality since December of that year. Tesla doesn’t know what the aliens might look like, but he believes they have adapted to living conditions on Mars. Like Lowell, he suggested that “it is possible that in a frozen planet, such as the presumed conditions on our Moon, intelligent beings could still reside, within it, if not within it. on the surface”. To many people, when humans can receive messages from Mars, we can also send messages, that seems reasonable. In 1909, there were attempts to find a contact with life on Mars. Harvard professor William Henry Pickering proposed sending planetary light signals through a series of reflections produced by a network of 50 giant mirrors. The flashes would continue to flash for several years, allowing the Martians time to develop the necessary means to respond. Professor Pickering’s giant mirror illustration for sending signals to Mars. Photo: Library of Congress “In the hope of receiving such signals again, we must of course assume that Martians, if they exist, have telescopes, eyes, etc., just like humans have on this Earth.” Mr. Pickering said. But the Harvard professor’s plan cost $10 million, and no one wanted to fund it.

A photo of Mars in April 2021. Photo: NASA The word “telepathy” with Martians… Then, a John Hopkins University professor named Robert Wood suggested covering the white alkaline earth plains of Nevada (USA) with giant black spots made of square kilometers of black cloth. “It might be easier to ‘blink’ the signals with dark spots like a mirror of the same size,” explains Mr. Wood. But like Professor Pickering’s plan, Mr Wood’s solution soon fell through due to a lack of funding. Another professor, David Todd of Amherst University, thinks that by raising a balloon 15,000 meters, he can get any message from Mars. “If life really did exist on Mars, they would have tried for years to talk to us, and perhaps wonder how stupid our behavior was for not responding to them,” said Todd. spoke in May 1909, months before the proposed flight was in September. The Tacoma Times reported on Professor David Todd’s plan for a hot air balloon to capture Mars signals on June 14, 1909. Photo: Library of Congress But Professor Todd’s balloon test flight only reached an altitude of 1,500 meters. Soon after, the support that David Todd received from the US War Department abruptly ended, leaving the scientist with no means to continue with his plan. The use of sound waves, mirrors, hot air balloons, and even giant black spots to “make contact” with any possible life on Mars has at least the backing of science. But on October 27, 1926, a London lawyer named Hugh Mansfield Robinson claimed it was “absurd” that he had tried to send a telegram straight to Mars, which is 56 million miles away from us. km, where “Mars girlfriend” is waiting for him! Dr. Robinson is confident that his message will reach the recipient. Mars was then closest to Earth in its two-year orbit. In addition, Robinson said he had a “telepathic” conversation with a six-meter-tall Martian woman named Oomaruru. According to Dr. Robinson, Oomaruru and her Martians live like Earthlings, driving cars and smoking pipes! However, he asserts, they fly through the sky in electric balloons and eat fruit from electric trees. For months before transmitting the message, Robinson worked with the Central London Telegraph Office to send a physical message to his “Mars girlfriend”. Incredibly, the Telegraph Office agreed to send a telegram from Rugby Tower, the most powerful wireless station in the world at the time, at a standard long-distance rate: 18 British cents per word, or about zero. 35 USD. Although the telegraph staff heard no response, Robinson claimed to have heard telepathically from Oomaruru. She told him that the Martians had “sitted for hours to receive the signal”. “They laugh at our scientists because they themselves are completely out of the trouble in the atmosphere, but we are not,” Robinson said. A “selfie” taken by NASA’s Perseverance probe in April 2021. Photo: NASA … to land on the “Red Planet” The ideas of the scientists who came before them seemed far-fetched, but their curiosity and relentless pursuit inspired generations to come. By 1976, the US Space Agency (NASA) had brought the search for life on Mars to the actual surface of the planet via two Viking landers. One of the metabolic reactions conducted by the lander also revealed positive results, suggesting that there may be life on the “Red Planet”. However, those results remain controversial to this day. Subsequent explorations of the landers have provided evidence that Mars may have once been very friendly to life. For example, the Curiosity rover, which landed in 2012, discovered a mountain in the middle of Gale crater on the Red Planet called Mount Sharp. This 4,800-meter-high mountain is formed from layered sedimentary rock, composed of different minerals, and has been formed over time by wind and water, two elements that require an atmosphere to exist. . helicopter (The Ingenuity Helicopter, from the Perseverance probe, has made many flights to Mars). Scientists believe that if there ever was an atmosphere around Mars, then perhaps microorganisms existed billions of years ago while the layers of material were forming, and the “Red Planet” has could have harbored life for about 1 million years. NASA’s Perseverance rover was launched on July 30, 2020 and landed on Mars on February 18, 2021. Most recently, on May 15, 2021, the Tianwen-1 probe and China’s first self-propelled Mars rover, Zhu Rong, successfully landed on the surface of the “Red Planet”. The mission of Thien Van-1 is to land a lander carrying autonomous robots to the surface of Mars to collect data on groundwater sources, looking for signs of ancient life on this planet. Any discoveries by landers from Earth could be microbial, but they will be no less remarkable than the “canal engineers” we had hoped to find on Earth. Mars from the 19th century.

The Space Launch System (SLS-yellow) core module is placed between the two boosters. Photo: NASA According to Insider, the US space agency (NASA) has just released new images of a super rocket called the Space Launch System (SLS) that has just been assembled. It is the agency’s most powerful launch vehicle since the 1960s. The SLS super rocket was installed on June 11 at Kennedy Space Center, Florida, USA. This is the first SLS rocket, part of a new type of rocket designed to serve the mission of sending American astronauts back to the Moon, and beyond to Mars. The core module of the SLS rocket. NASA has aimed to test-launch the SLS super rocket in November 2021, the first step in a series of missions toward the goal of returning to the Moon for the first time since 1972. In the photo released by NASA, the core module of the rocket, up to 65 meters long, is placed between two smaller boosters. The first version of the SLS super rocket is called Block 1. Once assembled, the rocket will weigh nearly 4 tons, 110 meters high, which is taller than the Statue of Liberty (93 meters). Powerful launcher capable of carrying over 27.2 tons into orbit. That capacity means it’s powerful enough to carry the Orion spacecraft, which is expected to send astronauts into space on future missions. See the core module of the super rocket SLS being moved from New Orleans to Mississippi: Before being fully assembled, the top of the SLS rocket core module needs to be fitted with a converter and the space capsule is lowered and placed on the rocket. This is the first time the core and two boosters have been coupled together since the SLS project was announced in 2011. Photo: NASA The SLS will be launched for the first time in November this year, sending Orion into orbit around the Moon on an unmanned mission. Assembling the core module onto the booster marks the end of the second phase of rocket assembly. NASA aims to launch the SLS super rocket on its maiden flight as early as October 2021. This is the first of three missions that NASA has planned to return humans to the Moon. If the mission is successful, the world will see the first black man and the first woman set foot on the Moon in 2024. The first launch of the SLS rocket this year will be unmanned as it aims to test the rocket’s ability to deliver the lunar space capsule and return to Earth.

Photo: NASA The boosters are located on either side of the core module of the SLS rocket, which can generate 3.6 million pounds of thrust in just two minutes to lift the rocket into space. The core module itself also has a powerful engine, generating about 2 million pounds of thrust. After the first failed test, the core modules’ engines were successfully launched in about 8 minutes on May 18, paving the way for rocket assembly. The engines will power the Orion spacecraft to travel at 24,500 miles (39,200km) per hour, the speed needed to get it to the Moon. Image of SLS system viewed from above. NASA also plans to use the SLS launcher to go to Mars. The modern SLS rocket is the equivalent of the Saturn V launcher, used in the Apollo missions. But because the Moon is 1,000 times farther from Earth, we need a more powerful launchpad. NASA has big ambitions for the SLS rocket. It is designed to be flexible and adaptable, and could be used for missions to Mars, Saturn or Jupiter. The next version of the rocket, Block 2, will be designed to carry a payload of more than 101,400 pounds (46,000kg). According to NASA, it will be a “pack horse” to help transport cargo to the Moon, Mars and other distant space destinations.

In some parts of Germany, it is believed that if you toast someone with a glass of water, it means you expect the person to die. This strange superstition has its roots in Greek mythology, where the spirits of the dead would drink from the Lethe, one of the rivers of hell. Knock on wood to avoid bad luck Illustration. Source: igafencu This superstition stems from the belief of the Paganists (a group of people originating from the Roman Empire following polytheism) that evil spirits often reside in wood. Therefore, it is believed that if you wish for something, you should touch or knock on the wood to prevent evil spirits from hearing it and prevent your wish from coming true. Avoid sitting at the corner of the table Hungarians and Russians believe that whoever sits at the corner of the table will never get married. Some say that this bad luck lasted only for seven years, but no one gave a clear explanation. Cut nails at night Illustration.

In ancient times, cutting fingernails and toenails was done with knives or sharp objects. It is possible that the wounds from cutting fingernails and toenails in the dark, plus the lack of medical support have caused infections or deaths, leading to such taboos. Put your wallet on the ground Avoiding putting your wallet on the ground is also a strange custom that still exists in many countries of Central America, South America and the Philippines. Many people believe that placing money or wallets on the ground will lead to bad luck with money. Put shoes on the table Illustration. Source: igafencu In the UK, placing shoes on a table is considered bad luck as it symbolizes the death of a loved one. This stems from an ancient custom, when placing someone’s shoes on the table was a way to announce that someone in their family had passed away. Today, although it no longer carries such a heavy meaning, putting shoes on the table is still considered an unacceptable act in etiquette. Fear of Tuesday the 13th Not only is Friday the 13th taboo, in Spain and some Spanish-speaking countries, people are very afraid of Tuesday the 13th. The word “Tuesday” in Spanish is “Martes” which is derived from the word “Tuesday” in Spanish. Mars, the Roman god of war. Additionally, Constantinople (once the capital of the Roman Empire) is said to have fallen and was devastated on Tuesday, during the Fourth Crusade. More than 200 years later, history records that the Ottoman Empire announced the occupation of the city on the same Tuesday.

Specifically, before someone goes away or performs a job, people will pour water behind this person’s back to pray for good luck, hope for a safe road and favorable work. This custom is usually done when entering school, before the exam day, before going to a job interview, enlisting in the army or similar important things.

Photos taken on Mars show many features similar to the glaciers in Antarctica. If these covered glaciers do, in fact, exist, they could be a reason to direct future Mars rovers towards this region. This location is inherently attractive to SpaceX and NASA because it is a wide, flat plain that is ideal for landing spacecraft. If there was ice not too deep below the surface, astronauts could also easily have a source of water within reach. Lead researcher Shannon Hibbard, a doctoral student at the University of Western Ontario, Canada, said the newly discovered flow-like features are very strange because they appear on flat terrain. “There’s a lot of evidence that this is an ice-rich area, but we don’t have any confidence that there could be a glacier in places with tortuous features,” said Hibbard. this. They’re existing in a pretty flat plane, so that’s odd.” Mysterious terrain Arcadia Planitia is located in the northern lowlands of Mars. Over the past 3 billion years, lava flows have been active over this area, so it is much less prone to crater cracking than other areas of the planet. Data collected from orbit over many years shows that the ground in the region is rich in hydrogen. Because water is made of hydrogen and oxygen molecules, this hydrogen indicates the presence of ice just below the surface. For decades, scientists have noticed features on Mars that are associated with ice. Along the low hills, there are debris that looks like the flow of a glacier covered in a thin layer of rock. There are also veins in seagulls that look similar to glaciers flowing through valleys on Earth. Similar features also occur in Arcadia Planitia, says Hibbard. Lobate features occur near a set of mountains known as the Montes Erebus that rise from the plain. Images taken from orbit, thermal data showing the surface’s temperature during both day and night, albedo data showing the surface reflectance, dust cover information and altitude data, and topographic. glacial flow The tortuous features are a big mystery because they look like they were created by the flow of ice, but the terrain isn’t steep enough to explain why the ice moves, says Hibbard. “We had to try to figure out what they are, why do they have thermal symbols, why are they so bright all day and night, why do they have flow characteristics, why are they threaded?” she said. Analysis shows that these features are in fact ice-derived. The undulating shapes look similar to other features associated with slow-moving matter found on Mars, Hibbard said, and the data suggests that these spots are indeed rich in ice. The most similar-looking sinusoidal feature, says Hibbard, is the ice flows inside the Earth’s ice sheets, which are mainly found in Antarctica. These faster-moving ice flows are not well understood on Earth, much less Mars, Hibbard says, but they represent an example of ice flowing in fairly flat terrain. This is a controversial claim, says Hibbard, because most of Earth’s ice streams need at least a thin layer of liquid water at their bottoms to lubricate their flow. It’s not clear if water under the ice exists or ever existed on Mars, she said, and it’s not clear whether a wet background is needed to create ice flows on the Red Planet. One possibility could be that in the past, when Mars’ orbit was tilted differently than it is today and its climate was different, sub-glacial melting may have occurred. The study is published in the May issue of the journal Icarus.

Use a telescope to track the stars. Illustration: IT. Stay away from lights when observing the sky When using a telescope to observe the sky, determine for yourself reasonable objects and choose the right time and place to observe them. Strong light is the enemy of the astronomical observer. Therefore, stay away from city lights. If you are in the city, you can go to the quiet suburbs if possible. Otherwise, you should choose high positions and have a wide viewing angle to limit the effects of light pollution. Which objects are best for you to observe with amateur telescopes? Many young people after completing the telescope with their own hands feel disappointed. Because you have too much hope for a dream glasses without taking into account the reality factor. Remember, even the glasses that cost thousands of dollars that you order from the world’s leading manufacturers cannot allow you to see the colors shown in the photos taken on Google. Also, pay attention only to the brightest and most observable subjects. Which objects are the brightest? Except for the Moon, readers with basic knowledge of astronomy will think of Venus, Jupiter, Mars or Sirius – the brightest star after the planets in the system. However, Venus is not a good object to observe even though it is very bright. All you see is a yellow halo due to its thick and toxic atmosphere. Stars like Sirius, Canopus, although many times brighter than that, they are just distant balloons. It is not a reasonable target for observation through amateur optical telescopes. The best observed objects are the Moon first, followed by Jupiter, Saturn, Mars and a few galaxies, remarkable nebula. Don’t Observe When The Moon Is Full To observe the Moon, adjust the position of the eyepiece accordingly and aim at the vicinity of the semi-dark area during the nights between the 6th, 7th and 11th of the 12th lunar month. The full moon is a bad subject because it is so bright that it will obscure the craters and valleys you can see. You can solve this with a thin layer of glass called a moon filter, which will reduce the light of the Moon as it reaches your face. With industrial-grade telescopes, most have this. As for the homemade glasses, you can also design it yourself using a glass or a piece of blue plastic but still clear enough to see through it. Even so, the Moon should not be observed on full moon nights. Because in addition to it covering itself, it also obscures other attractive objects of observation, except, of course, on full moon days when the lunar eclipse occurs. You should have a map of the visible part of the Moon to compare when observing. These maps are now easy to find on the Internet and simply print out with any black and white printer. To observe the planets, it is best to choose the right time for good results. Planets have a different period than Earth, so they do not have a stable position like the distant star background. The easiest way is to use computer software to check the positions of the planets, or you can use free software downloaded at www.stellarium.org. Do not forget to set the exact location of the user and when you want to observe. It is advisable to choose days that are not full moons because the planets are in relatively high positions. Jupiter is the most observable object through amateur telescopes. Push your eyepiece a little deeper than when looking at the Moon and try to orient the lens because it will disappear instantly if you don’t keep your gaze exactly. Although it is not possible to see the colors as clearly as in the photos online that have been taken with exposure techniques, and through equipment thousands of times more modern than the amateur glasses you own, the colors Basic with brown lines, dark yellow is what you will see, and moreover the 4 Galilean satellites of this planet. Saturn is like Jupiter, just determine the right direction and fix the glass and you will easily observe it. The most interesting thing to look at this planet is its ring. However, it won’t be as colorful as you’re used to seeing in the photos, both the planet and the ring appear pale yellow. Next in the Solar System is Mars. But observing this planet is not very interesting because all you see is a faint red and maybe some black patches with faint ice caps at the poles if the telescope is relatively good. Anyway, this is the only planet in the Solar System that we can see some of its surface through amateur telescopes. One type of object that is very interesting to observe with amateur telescopes or, more neatly, tubes are bright galaxies and nebulae. Remember to push your eyepiece even further towards the objective so that you can observe the celestial bodies at infinity. The first notable is the Andromeda Galaxy (M31), a spiral galaxy. At a distance of nearly 3 million light-years, it emits light strong enough to be seen with the naked eye. Even with a small binocular you can see a band of light that seems to be a combination of countless small bright dots when directed towards it. What you see is billions and billions of suns like our own. Next is the Pleiades star cluster (M45), also known as the stellar group. It is also easy to recognize with the naked eye, it is a small group of 7 brightest stars located right in the constellation Taurus. Through binoculars or small telescopes, it can be clearly seen that it is a blue star cluster with many stars, including 7 brightest stars visible to the naked eye, so it is called the Seven Stars. This is an open cluster in the milky Way located 400 light-years from Earth. Another member you should look out for is the Orion Nebula (M42), an emission nebula with the same galaxy about 1,350 light-years from Earth. The Orion Nebula, although visible to the naked eye, is quite faint.

Humans have only found about 5% of the composition of the universe. So what is the remaining 95%? Although we know of its existence, we cannot see or study it specifically, directly because these components are invisible. Science fiction still frequently mentions the existence of other universes. In fact, in recent years, the scientific community is gradually accepting this hypothesis. A typical example is the multiverse theory, which comes from William James’s term of the same name in 1895. Accordingly, it is said that there are many parallel universes along with the one in which we live. The origin of cosmic rays has puzzled astronomers for a long time, who have spent a century studying the origin of these charged particles. However, the origin of this mysterious phenomenon remains an unanswered question. Since the birth and development of space science, a question that has always bothered the whole human society is whether there is anyone outside of Earth? Humans have launched spacecraft, explored many planets in search of other life, but so far, the above question has not been answered. Life likely existed on Mars and may even exist today. Mars used to have vast oceans. Scientists have found evidence that liquid water is still periodically flowing on the surface of Mars. Many countries are planning to send explorers to Mars to find the answer tree to this problem. Solar physicists have been baffled by the mystery of the Sun’s ability as it reheats its corona, the fragile crown surrounded by light that emerges brightly during a total eclipse. Crystal rain is a mysterious phenomenon that can only be seen in the universe. The star HOPS-68 is a star that closely resembles the Sun at its inception. Around this star exists a cloud of dust and gas, of which the main component is green olivine crystals. Due to the rather cold temperature of these dust clouds (about -170 degrees Celsius), the olivine crystals condense into small particles and fall like a magically beautiful blue crystal rain. Black holes are one of the great mysteries of the universe. This entity is one where the density of matter is greater than any other entity in the universe. With its huge weight, the black hole can bend time and space and nothing can escape if it accidentally falls into its gravitational field. Astronomers estimate that the Sun will destroy the Earth in about 6 billion years. Several theories about the end of the universe have been put forward. The universe can perish when all matter in the universe has the same temperature. That means all stars will perish and all matter will perish. Another opinion is that an event contrary to the Big Bang, the Big Crunch, will occur. If the universe continues to expand, eventually gravity will become too great, causing everything to contract. The entire universe will become a solid mass and the universe will come to an end. There is a mystery about the moon that has puzzled astronomers for a long time. That’s why only certain parts of the moon’s surface appear to have magnetic fields. But after conducting many tests and analyzing the moon’s surface, scientists believe that the moon once had a magnetic field – about 450 million years ago. Femi bubbles are giant and mysterious structures that arise from the center of the Milky Way and span about 20,000 light-years, accompanied by intense gamma rays and X-rays. Since it was first discovered until now, the Fermi Bubble has caused astronomers around the world a headache because it has not been able to find the origin of this giant gamma-ray structure.

Chinese people watch the rocket that sent the Tianwen-1 probe into space. Photo: AP The China National Space Administration (CNSA) announced on May 15 that the Tianwen-1 (Tianwen-1) probe had successfully landed on the surface of the “Red Planet”. “China has left its footprints on Mars for the first time, an important step for our field of space exploration,” Xinhua news agency said. The New York Times reported that since 1976, the US has successfully landed on Mars nine times. The Soviet Union in 1971 became the first country to send a lander to the surface of the Red Planet, but the mission was unsuccessful because the probe then stopped transmitting. Recently, China has continuously recorded new space science achievements. On the morning of April 29, China launched the first module to build its own Space Station (CSS). It seems that to catch up with the US and Russia, China’s ambitions do not stop at Mars and the space station. Moon Dream In January 2019, China was the first country to land a probe on the dark side of the Moon. The dark side can be understood as the night side of the Moon while the other side is observable from Earth due to receiving sunlight and is the day side. This is China’s second successful landing on the lunar surface, the first being in 2013. China is the third country in the world to successfully explore the Moon, after the US and Russia. In December 2020, China sent another probe to the Moon, which is Chang’e-5. On December 16, 2020, the Chang’e-5 spacecraft landed in Inner Mongolia carrying samples from the lunar surface. This is the first time scientists have collected samples from the lunar surface, after the Soviet Luna-24 mission in 1976. Moon samples brought back by Chang’e-5 are on display at the National Museum of China in Beijing. Photo: Getty Images China plans to launch three more spacecraft to the Moon by 2027. Beijing’s goal is to establish a base on the Moon that can be accessed by astronauts within the next decade. In March, the Russian space agency Roscosmos said it would cooperate with China in building a research station on the Moon. However, the two countries have yet to announce the details of this coordination plan. Serious competition The fragmentation of China’s Long March 5B missile falling into the Indian Ocean in May has drawn much criticism from international public opinion. In April, this Long March 5B rocket sent the core module into space to build China’s first space station. In the near future, China plans to carry out 11 more launches to complete the space station by the end of 2022. The International Space Station (ISS) jointly developed by Russia, the US and many countries will “retire” in 2024. It is still unclear what will happen next. The US National Aeronautics and Space Administration (NASA) advocates keeping the ISS operational for a few more years. Russia meanwhile announced it would withdraw from 2025. In the event that the ISS is completely shut down, China will be the only country that owns the space station. Accordingly, the Chinese space station named Thien Cung is expected to be able to host three astronauts operating at the same time. China has selected a team of 18 astronauts, including only one woman. The first three astronauts are expected to spend three months in space. Mars and more Model of China’s first space station. Photo: AP China announced that it plans to make one more Mars landing by 2028 and bring samples from the planet back to Earth for study. NASA and the European Space Agency are also embarking on this work in the hope that the US Perseverance probe, which landed on Mars in February, can bring soil and rock from Mars to Earth by 2031. This is said to be more likely to lead to a race between the parties. China also plans to take 10 years to collect samples from the comet. In addition, the country also intends to set up spacecraft to orbit around Venus and Jupiter. By 2024, China plans to launch a space telescope like the US Hubble, which has been in orbit since 1990. On China Space Day (April 24), President Xi Jinping wrote a letter to senior space scientists, encouraging them to “intensify and expand space exploration and rapidly quickly turn China into a space power.

Photo: India Express It is known that on May 15, China confirmed that Tiawen-1 had successfully dropped the Zurong rover to the surface of Mars. This is a historic milestone that makes China the second country to successfully launch a probe on the Red Planet. In the past, only NASA has succeeded in landing and operating probes on the red planet. (The Soviet Mars 3 spacecraft landed on Mars in 1971 and remained in contact for only about 20 seconds.) The landing took place at Utopia Planitia, a flat land on Mars and the same area where NASA’s Viking 2 rover landed in 1976. After landing, the lander dropped the Zhurong rover – Powered six-wheeled robot named after the god of fire in ancient Chinese mythology. The spacecraft carries an integrated toolkit, including two cameras, a Mars subsurface probe radar, a Mars magnetic field detector and a Martian meteorological tracker. “This is the hardest place to land in the solar system,” said Emily Lakdawalla, author of “The Design and Engineering of Curiosity.” China’s success in its first attempt indicates that it is one of the most capable space agencies.” The European Space Agency also tried to land on Mars in 2003, but its Beagle 2 probe had problems. The ExoMars Schiaparelli spacecraft – another ESA (European Space Agency) effort also crashed in 2016 after software mis-estimated its altitude during a landing attempt. Photo: The Verge The Tianwen-1 spacecraft launched from Wenchang Launch Site in Hainan Province, China last July, embarking on a seven-month trip to Mars. China said that “Tianwen-1 has been operating normally since it entered the orbit of the Red Planet,” the China National Space Administration (CNSA) said in a statement on the morning of May 15. CNSA revealed that Tianwen-1 has collected a large amount of data and photos taken from the orbit of Mars. Andrew Jones, a journalist covering China’s activities in space, said that Tiawen-1 has been exploring the Utopia Planitia landing site for more than three months while orbiting Mars. Now, after a successful landing, the Zhurong rover will embark on a mission that will last at least three months to study Mars’ climate and geology. “The main mission of the Tiawen-1 mission is to conduct a comprehensive and extensive survey of the entire planet using orbiters and to bring the probes to surface locations of great scientific interest. focused to conduct detailed investigations with precision and high resolution,” the leading scientists wrote in Nature Astronomy last year. It is known that this expedition vehicle weighs about 240kg, nearly double the weight of China’s previous Yuto Moon. The CNSA said last month: “The Mars rover Zhurong is hoped to ignite the fire of China’s interplanetary exploration and guide humanity into the vast unknowns of outer space.” Photo: The Verge Before Tiawen-1 successfully landed on Mars, the United States also successfully landed 5 rovers on the surface of the Red Planet. More recently, on February 20, 2021, NASA’s Perseverance probe passed through the atmosphere of Mars and landed on the planet on a historic mission to recover rocks to help answer the question. whether life ever existed on Mars. Although this CNSA project is more than four decades behind NASA, this success of China shows that its space engineers are rapidly closing the gap with the US. Tiawen-1 marked a big step for China in the field of space exploration. Previously, China also became the first country to successfully land and operate a probe in the dark side of the Moon in 2019. Recently, China also successfully launched its first core module. Chinese space station. In the future, this will be inhabited by groups of astronauts in space. Earlier this year, China, in partnership with Russia, announced plans to build a space station on the surface of the Moon.

Due to the presence of minerals and other resources on the Red Planet, in the future, Mars could be an abundant source. All in all, the initiatives in this direction are impressive, but as always, there are nuances attached to them. Traveling to Mars on 1,000 rockets and creating land for 1 million earthlings as Elon Musk suggests is an extremely expensive and technologically difficult task. It is not necessary to list all the problems that arise when massive scientific works are devoted to this, just to mention the main “knots”. First, There is no technology that allows the creation of spacecraft with the ability to send people into distant space without having to receive a lethal dose of cosmic radiation. This problem could be solved by wrapping lead plates, but would lead to a proportional increase in the mass of the ship and a decrease in its carrying capacity. New engines were needed, but they are now beyond production. Monday, Solar radiation will remain a problem on the Martian surface. The Red Planet, unlike Earth, does not have a magnetic field that protects us from ionizing radiation. Astronauts will not have to walk on red sand dunes like in the movie “Total Recall”, but have to hide in bases hidden deep below the surface. Tuesday, Mars on Mars is cold and has practically no atmosphere, but the radiation background is 2.5 times higher than what astronauts on the ISS can tolerate. It is impossible to live in such conditions without a special space suit. There are also many other problems, but it is clear that expanding living space is an extremely important task for all of humanity, requiring accumulation and huge investments in technology. For this reason, scientists are seriously skeptical of Elon Musk’s initiative, especially when he proposes to carry out thermonuclear bombardments at both poles of the Red Planet. This will lead to higher temperatures, melting glaciers, the formation of liquid water and the release of greenhouse gases, which will create the atmosphere on Mars. After that, the settlers could walk on the surface without the spacesuit. But there is another way of looking at this “terrain” approach. Mathematician Robert Walker calculates that in order to carry out the first part of the plan, which would require at least 1 million nuclear bombs with a capacity of 100 megatons, they would have to be sent to Mars 3,500 a day for seven weeks to achieve. desired results. There are no such large numbers of nuclear weapons on Earth and the lack of means to deliver them to another planet. This is the first thing. Carbon dioxide reserves on Mars would not be enough to create a suitable atmosphere, even if the first problem were solved. Since the Red Planet has no magnetic field, solar radiation will gradually “suck” in the already formed magnetic field. This is the second thing. And finally, for some reason, Elon Musk doesn’t take into account that after so many nuclear explosions, the surface of the planet will be radioactive for a long time, you can’t walk there with a mask oxygen and plant trees. “Nuke Mars” is just a cover for the US to send nuclear weapons into space? In general, Elon Musk’s initiative is a nonsense and he himself cannot help but understand this. But why is this smart man promoting it? The head of Roscosmos – Mr. Dmitry Rogozin tried to answer the question: Anyone who calls for the “terrain” of Mars or other planets is well aware that this is just an excuse for launching nuclear weapons into space, which, if useful, is just to “terrain”. our “Earth. But it’s true, you can’t just send nuclear warheads to Mars. First, they will need to be put into orbit and accumulate somewhere along with the means to send them in large batches. Where is that? Suppose that a circular orbit station, which the United States and its allies are building, will be adapted for this case, with China and Russia as targets. But will the nuclear bomb then make its way to the Red Planet? It’s long been no secret that Elon Musk is working closely with the Pentagon on the space program and satellites. So why not try with the best cause, Mars exploration, to advocate for the idea of ​​​​putting a US nuclear arsenal in space, Mr. Rogozin concluded.

The idea of ​​​​conquering Mars has been a dream of mankind for many years, this could be the first step towards realizing the dream of many science fiction scientists that is to explore outer space. Sending humans to another planet, even within the solar system, has the effect of reducing the risk of a global catastrophe that could destroy life, such as a large asteroid impact or nuclear war. Even in the future, the Red Planet could be an abundant source of resources. Obviously the ambition to travel to Mars is impressive, but there are many doubts and obstacles attached. Tech billionaire Elon Musk put forward the idea of ​​humans traveling to Mars on 1,000 rockets and creating land for 1 million inhabitants, this is clearly an extremely expensive and technologically difficult task. major barriers have been listed. First, Earth science has not yet been able to create spacecraft with the ability to send humans into distant space that is “immune” to deadly cosmic radiation. The solution to this problem could be to wrap lead plates, but that would increase the weight of the ship and reduce its carrying capacity. Engines for spaceships are now well beyond construction. Second, solar radiation is a big problem, the Red Planet is different from Earth in that it doesn’t have a magnetic field protecting it from ionizing radiation. Astronauts will have to hide in bases hidden deep below the surface, not be able to walk freely on the surface. Third, Mars is cold and has no atmosphere, but the radiation background is 2.5 times higher than that of astronauts on the International Space Station ISS. It is impossible to live in such conditions without a special space suit. There are many other problems as well, but it is clear that expanding space into outer space requires accumulation and huge investments in technology. Before this fact, scientists expressed doubts about Elon Musk’s initiative, when he proposed to carry out bombardments with thermonuclear warheads at both poles of the Red Planet. A “fusion attack” would cause glaciers to melt, forming liquid water and releasing greenhouse gases, which help create the atmosphere on Mars. Then the “reclaimers” could walk around without a spacesuit. But mathematician Robert Walker calculates that to carry out the first part of the plan requires at least 1 million nuclear bombs with an explosive yield of 100 Megatons, must be assembled on Mars 3,500 a day for 7 weeks to achieve desired results. There are no such large numbers of nuclear weapons on Earth, and the lack of means to deliver them to another planet, is the first hurdle. CO2 reserves on Mars would not be enough to create a suitable atmosphere, even if the first problem were solved. Since the Red Planet does not have a magnetic field, solar radiation will gradually “suck” the gas that has already formed, which is the second barrier. Finally, Elon Musk does not take into account that after many nuclear explosions, the surface of the planet will be radioactive for a long time, people cannot walk with oxygen masks and plant trees. Elon Musk’s initiative is clearly impractical and perhaps the billionaire himself understands this, but what is his meaning. The head of Russia’s state space corporation Roscosmos – Mr. Dmitry Rogozin made a remarkable remark. “Anyone calling for the reclamation of Mars or other planets is well aware that this is just an excuse for launching nuclear weapons into space for military purposes on Earth.” “It’s true, you can’t just put nuclear warheads on Mars. They need to first be put into orbit and assembled somewhere with the means to send them in large batches.” “Assuming an orbital station being built by the US and its allies will be tailored to target China and Russia. Will nuclear warheads reach the Red Planet then? “It is no secret that Elon Musk is working closely with the Pentagon on the space and satellite program. So why not experiment with the best cause of Mars exploration, to advocate for the idea of ​​​​putting US nuclear weapons in space,” concluded Mr. Rogozin.

The Global Times (China) on the morning of May 15 reported on the successful landing on Mars of the Tianwen 1 mission. According to RT (Russia), the Tianwen 1 (Tianwen-1) spacecraft of the China National Space Administration (CNSA) was successfully launched from Wenchang Launch Site on July 23, 2020 and orbited Mars since February 10 this year. This interplanetary mission is China’s second attempt to reach the “Red Planet” after the 2011 Mars mission of the Huang Huo 1 (Yinghuo-1) probe. Citing CNSA sources, Chinese state media confirmed that the Tianwen 1 spacecraft successfully landed the Zhu Rong (Zurong) rover on the Martian surface on the morning of May 15. Thien Van 1, weighing 5,000kg, includes an orbiter, a lander and a golf cart-sized rover called Chuc Dung, named after an ancient fire god in the god of fire. Chinese phone. Carrying the Chuc Dung rover, the lander endured “seven minutes of horror” as it plowed through the Martian atmosphere on a parachute support lander. The spacecraft landed in Utopia Planitia, the same area where NASA’s Viking 2 mission landed in 1976. Watch a simulation video of the Chinese lander’s landing on Mars: (Source: Global Times) Earlier, in a statement on the same day, CNSA said, “The Tianwen 1 probe has been operating normally since its successful launch on July 23, 2020”. The agency added that it had collected a “massive amount” of scientific data as the Tianwen 1 rover orbited Mars. “With the assessment of the flight status, the Tianwen 1 probe is scheduled to conduct a landing operation against the Utopia Planitia area at the appropriate location from the early morning of May 15 to May 19 according to the Beijing time,” the CNSA statement said. The Utopia Basin is the largest recognized basin on Mars, with a diameter of about 3,300 km. Graphic image of China’s probe landing on Mars.

According to The Verge, China is planning to land a pair of robots on the surface of Mars, making a daring attempt to become the second country to successfully land and operate a rover on Mars. Red Planet. China launched the unmanned Tianwen-1 spacecraft from the southern island of Hainan in July 2020, with the goal of sending a rover to the surface of Mars to collect data about the source groundwater and look for possible signs of ancient life there. So far, only the US has successfully implemented the technique to bring the rover to Mars and operate it. After a journey of nearly 7 months, the Tianwen 1 spacecraft successfully moved into Mars’ orbit on February 10 and then sent back to Earth many high-definition pictures of the Red planet’s surface.

The country became the first country in history to land and operate a probe on the far side of the Moon in 2019. Beijing also completed a lunar sampling mission last December. , with launching a robot to the Moon and quickly returning it to Earth carrying soil samples. Tianwen 1 is China’s first Mars landing mission, but it’s not the country’s first attempt to send a probe to Mars. The first is a fairy orbiter called Huynh Hoa 1, launched in 2011 with Russia’s Phobos-Grunt mission. This ship did not go beyond Earth orbit after launch, plunged into the Pacific Ocean and was destroyed. Before the successful Mars landing of the Tianwen 1 mission, the US successfully landed 5 rovers on the surface of the Red planet. Most recently, on February 20, 2021, NASA’s Perseverance probe passed through the Martian atmosphere and landed on this planet, with the historic mission of bringing back the rocks to help answer the question. whether life ever existed on Mars. On May 28, 1971, the Soviet Union also launched the Mars probe Mars 3, nine days after its “twin” spacecraft, Mars 2, was launched. Illustration of the Soviet Mars 3 probe on Mars. While making a Mars landing on November 27, 1971, the Mars 2 lander crashed to the Martian surface and disappeared in a dust storm. Then, Mars 3 landed in the Ptolemaic crater area in the southern hemisphere of Mars on December 2 of the same year. At first it seemed that Mars 3’s landing went perfectly, but just 110 seconds after landing, the device disappeared in silence. Since then, the Russians have not received any signal from the ship.

Photo: Kin Cheung / Associated Press China has now achieved what the US and the Soviet Union did before: a successful landing on Mars. After orbiting the planet since February, the Tianwen 1 rover sent a vehicle to land on the surface of Mars. The probe will join three NASA spacecraft that are surveying Mars. China’s Mars mission may seem less appealing than NASA’s latest mission, because it’s essentially repeating the feats Americans achieved decades ago. But it represents another milestone in China’s ambitions to transform itself into a “space power,” as President Xi Jinping announced in April. Many potential milestones lie ahead. Conquer the Moon In January 2019, China became the first country to land a probe on the dark side of the Moon. This is China’s second successful moon landing, after one in 2013. At that time, China sent a rover on the lunar surface and it is still operating to this day, far exceeding the initial 3 month expectation. In late April, it roamed nearly half a mile from its starting point in the Von Kármán crater near the moon’s south pole, according to Chinese television. In December 2020, China sent another spacecraft to the Moon. It shoveled nearly 2kg of rock back to Earth. This is the first lunar specimen since those collected by the Soviet Union during the Luna 24 mission in 1976. Some samples are on display in Beijing. China names its lunar probes Chang’e with serial numbers. Three more will hit the road in 2027, with more flying probes and even 3D printing trials in space. These missions aim to lay the groundwork for a Moon base and astronaut visits in the 2030s. To date, only the US Apollo program has sent people to the Moon. In March, Russia’s space agency Roscosmos said it would work with China to build a lunar research station, though it did not give details of any joint plans. Enemy space station China’s launch of the main module for its latest orbiting space station in April attracted more international attention than expected for unwarranted reasons. After reaching orbit, the main booster fell ominously back to Earth: “uncontrolled re-entry”. Debris landed in the Indian Ocean in May, nearly losing the Maldives and sparking criticism over how China carried out its heaviest rocket launch, the Long March 5B. More similar cases will continue. This is the first of 11 missions needed to build China’s third and most ambitious space station by the end of 2022. Two more Long March 5B rockets carry additional modules and new ones. Variations with smaller parts. Next June will have four missions to be carried out, sending Chinese astronauts back into space after more than four years. Watch the launch of the rocket carrying the Mars probe Tianwen 1 in Wenchang, China. Photo: AP China’s first two space stations are short-lived prototypes, but the station is intended to be operational for a decade or so. The International Space Station, jointly developed by the US, Russia and other countries, is nearing the end of its expected life cycle in 2024. What happens after that remains unclear. NASA has proposed keeping the station operational for several more years; Russia has announced it intends to withdraw its troops by 2025. If the station is shut down, China could be the only country with a space station for a while. This Thien Cung station will be able to accommodate 3 astronauts for long-term missions and 6 astronauts for shorter periods. China has chosen a team of 18 astronauts, some of them civilians (only one is a woman). The first three are expected to spend three months in space, surpassing the 33-day record set by Chinese astronauts in 2016. Hao Chun, director of China’s manned space agency, told the press that astronauts from other countries would be allowed to visit, under the docking mechanism “in line with China’s standards”. “. Some foreign astronauts are prepared to learn Mandarin. Conquer Mars The Mars mission is trying to achieve feats that NASA has achieved for many years. The Tianwen 1 spacecraft has reached orbit around the planet and has now safely brought one to the surface. The Soviet Union was the first country to send a spacecraft to Mars in 1971, but seconds after touching down, the lander stopped communicating, possibly due to a sandstorm. It transmits an incomplete or undecipherable image. Since then, several other countries’ attempts to reach the surface have failed. Only the US has succeeded in landing on Mars. China tried to send an orbiter to Mars in 2011, but the Russian rocket carrying it failed to get out of orbit and both crashed back to Earth. China’s Tianwen Orbiter has surveyed Mars and its landing site, Utopia Planitia, a large basin in the northern hemisphere where NASA’s Viking 2 landed in 1976. The Zhurong rover is named after a position. god of fire, will conduct a number of experiments studying the topography, geology and atmosphere of the planet. China says it plans to send a second lander to Mars in 2028 and eventually return samples from the planet to Earth. That’s a goal NASA and the European Space Agency are hoping to achieve by 2031. China’s mission could happen this decade, setting up a potential race. In addition to the Mars mission, China is planning a 10-year mission to collect samples from an asteroid that passed by the comet. Simultaneously in orbit for Venus and Jupiter. In 2024, they plan to launch a telescope with an orbit similar to Hubble, which was first launched in 1990. Hoang Thanh ( According to the New York Times)

Astronaut in space. Illustration. Many plans have been proposed, such as “launch” ill-fated astronauts into space, burial on Mars, even used as food for the crew. If there is a problem on the flight itinerary We are entering an exciting space era, in which many hope human’s first step on the surface of Mars will not be far away. However, as SpaceX CEO Elon Musk once said, “If you want to go to Mars, prepare for death.” About 21 astronauts have been killed since humans first set foot on a spacecraft and flew into space 60 years ago. According to experts, the death toll will inevitably increase as space agencies prepare for missions to send humans to Mars. To get to the Red planet, astronauts spend at least seven months living inside a cramped spaceship, traveling long distances, deep. If they survive this journey, they will have to endure the harsh environment of the Martian world. When a crew member dies while on a mission, it will take months, even years, for their bodies to be brought back to Earth. This situation raises a question: What happens to the body of a dead person in space? NASA does not have procedures to handle corpses in space because the astronauts selected for the mission are guaranteed physical and mental health. However, researchers around the world have thought of this situation and proposed measures to handle when an astronaut accidentally dies. During the mission on the journey to Mars, can the astronaut’s body be placed in cold storage or freeze-dried until the spacecraft returns to Earth? The process of freezing drying in space is much different from that on Earth. On Earth, people would use liquid nitrogen to freeze bodies, but in space, a robotic arm would hang the body wrapped in a bag on the outside of a spacecraft. The body will freeze for an hour, become brittle, then the arm will shake, breaking into small pieces. This process will theoretically turn an astronaut weighing 90kg into a mass of only 22kg, which can be stored on a spaceship for many years. But if this freeze-drying isn’t an option, the crew can send off their deceased companion to stay forever in the vast universe. Catherine Conley of NASA’s Office for the Protection of the Planet told Popular Science: “At the moment, there are no specific guidelines in the plan to protect the planet, either at the NASA level or internationally, regarding” bury “a deceased astronaut by throwing the body into space”. The solution of releasing the dead into space seems to be the easiest option, the body will stay on the spacecraft’s journey and linger on the place where it was released. And if more missions choose this approach, future spacecraft heading towards Mars will likely collide with many corpses. The robotic arm holds the dead body in space waiting to freeze. Illustration. Bad situation going to Mars If you are lucky enough to survive on a journey that lasts approximately 7 months and reach Mars, astronauts will face new challenges that threaten their survival, radiation. Previous data showed that Mars is 700 times more contaminated with radiation than Earth. Radiation can alter the cardiovascular system, damage the heart, harden and narrow the arteries, or remove some of the cells in the lining of blood vessels, leading to cardiovascular disease and may end with the death of the astronaut. In this case, burial on Mars would be necessary, but NASA has strict laws about contaminating other planets from microorganisms on Earth. NASA scientist Conley told Popular Science: “Regarding the disposal of organic matter (including corpses) on Mars, we are not imposing any restrictions as long as all are eliminated. microorganisms on Earth. So it is necessary to cremate ”. However, not every dead astronaut can be buried, but in some emergency situation, such as when the remaining crew runs out of food and in order to survive, the corpse of the human. The team can help them sustain life on their way back to Earth. It sounds barbaric, but there has been such a case in the past, when a plane crashed into the Andes in 1972. The survivors had no food and no way to communicate with them. outside, so in order to sustain life, to find someone to come and save, they made the difficult decision to eat the dead as soon as the plane crashed. Biologist Paul Wolpe said: “Although we give our bodies a lot of respect, life is everything. If the only way a human could survive was to eat a body, then that would be acceptable, even if no one wanted it.

Mars probe ship. Generates oxygen on other planets The Perseverance expedition ship of the US Aeronautics and Space Administration (NASA) has just made history. It successfully experimented with converting carbon dioxide gas from the Martian atmosphere into oxygen. This is the first time that oxygen production has been performed on another planet. The Mars experiment using local oxygen resources, called MOXIE, is a device the size of an automobile battery and is placed inside the Perseverance. Massachusetts Institute of Technology (MIT) is the manufacturing unit. MOXIE is made of a heat-resistant material such as a nickel alloy. It is designed to withstand extreme temperatures of up to 800 degrees Celsius. The device is coated with a thin layer of gold to prevent heat and damage to the Perseverance vessel. On the first test run, MOXIE generated 5.4 grams of oxygen – enough for an astronaut to breathe easily for 10 minutes while still performing normal activities. Engineers will conduct additional tests and find ways to increase oxygen production. By design, MOXIE can generate 10 grams of oxygen per hour. NASA expects the development of experimental instruments not only to help generate oxygen for astronauts in the future, but also to help generate large amounts of oxygen to be used as a rocket launcher for the return journey without. must be transported from Earth. The Perseverance expedition landed on Mars on February 18 to perform a mission to search for signs of microbial life on the “Red Planet”. In the coming years, the Perseverance ship aims to collect 30 soil and rock samples to send back to Earth (estimated around 2030) for analysis. Dang Vu Tuan Son, Club of Astronomy and Astronomy of Vietnam, said that oxygen-rich atmosphere should not be seen as steel evidence for life on other planets. Nowadays, to look for signs of life, scientists often use biological structures as guides. Its biological form and life-forming compounds serve as indirect evidence for its presence. On Earth, the oxygen in our atmosphere is one of the most obvious biological characteristics that an alien astronomer can notice. It is only in our atmosphere in such large quantities because plants and bacteria photosynthesize it has been creating it for billions of years. Oxygen is not synonymous with life A new study published April 13 in the journal AGU Advances suggests that terrestrial planets around stars like the Sun can develop oxygen atmospheres without help. from life. This means that detecting oxygen on a planet does not mean that the planet is capable of life. This study uses a computer model that allows scientists to experiment and observe the evolution of a planet. In the first model test, the researchers attempted to accurately reconstruct our Earth. Then they changed the initial conditions to different from what was made up of Earth, and the results they got showed that there are many cases where the planets still contain oxygen but do not require any changes. living. In fact, they have found three main ways for a rocky planet to have an oxygen-rich atmosphere without the presence of life. The first scenario is an Earth-like liquid water planet with oceans 50 times (or more) larger than on Earth. All of that water puts great pressure on the planet’s crust, shutting down the geological activity. This prevents things like the weather and the melting of rocks being two factors that cause oxygen to disappear from the atmosphere. The second scenario is the opposite: A dry desert world with 30% less water than Earth and they will solidify with a “steam atmosphere” for about a million years. This provides a large amount of oxygen in the atmosphere, as sunlight breaks down the molecules of water and hydrogen released into space. And because the planet’s solid desert surface cannot remove any oxygen, it stays in the atmosphere. The last way for a lifeless planet to have an oxygen-rich atmosphere is if the original planet had a higher ratio of carbon dioxide to water than the early Earth. In this case, the planet undergoes a greenhouse similar to what happened on Venus and becomes too hot for oceans to form in the first place. It is also too hot for volatiles to exist in the planet’s mantle, where they will isolate oxygen through chemical reactions. Instead, these volatiles are in the atmosphere, where they can no longer remove oxygen. The planets could have better life than the Earth Researchers have identified more than 20 planets outside the Solar System that have better conditions for life than Earth. Some of these planets have orbits stars that are probably even better than the Sun. A study led by Dirk Schulze-Makuch at Washington State University published in the journal Astrobiology details the features of planets with superlative potential, including is composed of planets that are older, slightly larger and warmer, and possibly more water than Earth. Life can also easily develop on planets moving around slower-changing stars that have longer lifespans than the Sun. The top 24 candidates for habitable planets are all located more than 100 light-years away from us, but Schulze-Makuch says this rescue could help future observations to focus properly, such as the James Webb space telescope, NASA’s LUVOIR space observatory and ESA’s PLATO space telescope. Researchers have selected planetary systems that are likely to have terrestrial planets moving around the parent star in the region of the habitable zone (an area that allows water to exist as a liquid on the planet’s surface) from Kepler’s archival data on transiting exoplanets. Our sun has a relatively short lifespan, less than 10 billion years, because it takes nearly 4 billion years for complex life to form on Earth, so many stars are similar to the Sun (types of G stars). ) may run out of fuel before life can develop. Along with monitoring the types of G stars, the researchers are also observing K-stellar systems, which are colder, smaller, and fainter than the Sun. Type K stars have lifespans that can last from 20 to 70 billion years. That allows the planets moving around it to grow older and allow life to have more time to have life as complex as Earth does today. However, for the planets to stay alive, the planets could not be too much as they could end geothermal activity and no longer have a protective magnetic field. Earth is about 4.5 billion years old today, but researchers think that the most ideal time for life on a planet is between the ages of 5 billion and 8 billion.

Photographs taken on Mars show many glaciers-like features in Antarctica, If these covered glaciers do, in fact, exist, they could be a reason to direct future crews to Mars towards this area. The location was inherently attractive to SpaceX and NASA because it was a wide, flat plain, ideal for landing spacecraft. If there is ice that is not too deep below the surface, the astronauts can also easily have water within reach. Lead researcher Shannon Hibbard, a graduate student at the University of Western Ontario, Canada, said the newly discovered flow-like characteristics are very strange because they appear on flat terrain. “There is a lot of evidence that this is an area with a lot of ice, but we don’t have any confidence that there could be a glacier in places with winding features,” Hibbard said. this. They exist in a fairly flat plane, so that’s weird. ” Mysterious terrain Arcadia Planitia is located in the lowlands north of Mars. In the past 3 billion years, lava flows have been active in this area, so it is much less prone to cracking with craters than in other areas on the planet. Data collected from orbit over many years show that the ground in the area is rich in hydrogen. Because water is made up of molecules of hydrogen and oxygen, this hydrogen shows the presence of ice just below the surface. For decades, scientists have found features on Mars to be related to ice. Along the low hills, there are debris that look like a glacier flow covered in a thin layer of rock. There are also patterns in gulls that look similar to glaciers that flow through valleys on Earth. Similar features occur in Arcadia Planitia, Hibbard said. Lobate features occur near a set of mountains called Montes Erebus that rise up from the plain. Orbital images, thermal data showing surface temperature during day and night, albedo data showing surface reflectivity, dust cover information and altitude data, and topographic. Glacial flow The winding features are a big mystery, Hibbard says, because they look like they were created by the flow of ice, but the topography is not steep enough to explain why the meteor was moving. “We had to try to figure out what they are, why they have thermal symbols, why they are so bright day and night, why they have flow characteristics, why Are they threaded again? ”she said. The analysis showed that these traits were in fact derived from ice. The curled shapes look similar to other features related to slow-flowing matter seen on Mars, Hibbard said, and the data shows these points actually contain a lot of ice. The most similar sinusoidal feature, Hibbard says, is the currents inside the Earth’s ice sheets, which mainly occur in Antarctica. These faster moving ice currents are not well understood on Earth, much less than Mars, but they do show an example of ice flowing in fairly flat terrain, Hibbard says. This is a controversial claim, Hibbard says, because most ice currents on Earth need at least a thin layer of liquid water at their bottom to lubricate their flow. It is unclear whether sub-ice water existed or existed on Mars, she said, and it is not clear if a wet background is needed to create ice currents on the Red Planet. One possibility might be that in the past, when Mars’ orbit was tilted differently than it is today and its climate was different, melting under ice may have occurred. This research was published in the May issue of the journal Icarus.

The Starship SN15 space missile left its launch pad on May 4. Photo: Space According to Space page, on May 5, SpaceX successfully landed the Starship spacecraft during the fifth test at their base in Texas, USA. This successful experiment marks a big win for billionaire Elon Musk’s space company after four of the previous tests ended in explosions. The SN15 rocket took off from Starbase in Boca Chica, south Texas at about 17:25 local time, reached around 10km and performed a series of flight exercises before making a critical landing. Billionaire Musk happily posted on Twitter: “Starship is landing normally”. Watch the video of the Starship rocket launched and successfully landed for the first time (Source: SpaceX): The test, however, was not entirely perfect. A small fire engulfed the base of the 50-meter spaceship shortly after landing, but was quickly extinguished with a tornado. SpaceX expert John Insprucker explains this “it’s no stranger to the metal fuel we’re using,” adding that engineers are still solving design problems. SpaceX faces growing pressure to succeed with its May 4 test flight after NASA announced a version of the Starship would be used as a lander in its return to the Moon program. America. The $ 2.9 billion contract is currently on hold after two rival companies, Blue Origin and Dynetics, filed an objection. SpaceX Starship Ship Illustration on the Moon. Photo: SpaceX Along with SpaceX, the space company Blue Origin of billionaire Jeff Bezos is also expected to launch the first space travel flight in July. Previously, the four predecessor devices of the Starship SN15 ship ended in failure, broken to pieces in tests over the past five months. The most recent time in early March, the SN10, appeared to have landed safely but a fire suddenly erupted as soon as the ship touched the launch pad, causing it to explode into a fireball. A small flame also erupted at the base of the SN15 in the latest launch but was quickly extinguished. Video of Starship SN10 ship exploded after landing (source: videospace): SpaceX has learned a few lessons from other tough landings. And the SN15 has been revised with a slightly different look from the previous prototypes. “The SN15 has improvements in structures, avionics and software, and the engine will allow for increased speed and efficiency throughout production and flight: in particular, avionics. No new improvements, updated launch architecture and new Raptor engine design ”, a SpaceX representative wrote in the flight description on May 4. SpaceX is developing Starship to send people and goods to the Moon, Mars and other distant destinations. The system consists of two components, both of which are designed for fast and complete reuse. The two components are a spaceship called the Starship and a giant early stage booster booster called the Super Heavy. Both vehicles will be powered by SpaceX’s next-generation Raptor engine. SpaceX founder and CEO Elon Musk said the Starship will have six Raptor engines. Although the SN15 was just a full-scale Starship prototype in height and width, it was powered by only three Raptor engines. Future test variants will be stronger, Musk said, and we will soon see these more powerful means of carrying out space missions. Musk aims to launch the Starship into orbit before the end of the year. Three Raptor engines of the SN15 missile in successful test. Photo: Space Starship SN15 ship when about to land. Photo: Space NASA’s Artemis moon exploration program recently selected Starship as a manned lunar lander Artemis aims to establish a lasting, enduring human presence on and around the Moon by the end of the 2020s. NASA officials say the knowledge and skills gained during SpaceX’s testing efforts. will help humanity reach Mars in the 2030s. Over the past few years, NASA has worked to achieve its goal of making a human landfall on the moon by the end of 2024, at the direction of former President Donald Trump. However, this timeline is expected to be relaxed under President Joe Biden.

Photo of the Ingenuity Mars helicopter taken by NASA’s Preseverance spacecraft. Photo: NASA. Open a new door Ingenuity attached to the belly of the Perseverance probe landed together inside Mars’ 45 km wide Jezero crater on February 18. On April 3, a solar-powered helicopter was dropped from Perseverance’s belly. NASA is expected to make history on the Red Planet with its first self-powered flight powered by energy. “That is extremely important. Technological inventions will open a door to completely different tools. And for me, that’s very interesting. We still haven’t envisioned all the benefits of this new technology, ”said Thomas Zurbuchen, NASA’s Deputy Administrator. Ingenuity is considered a “technology show”. Because, the expected flight of this helicopter on Mars is designed simply to demonstrate the efficiency of the technology. Although there is an onboard camera to take pictures during the mission, it’s the only feature on the plane that is not directly related to Ingenuity’s take-off. “The speed of light is too slow for us to actually control it in real time,” said Mr. Zurbuchen. In addition, the team must find a way for the helicopter to fly over Mars in a challenging environment, with a very thin atmosphere. Obviously, flying on another planet is not easy for helicopters. This is an exciting moment in the history of spacecraft and technology. Many people questioned whether Ingenuity was equipped with any technology application to achieve such a feat. Scientists hope to use Ingenuity to explore in the future, according to Zurbuchen. Because, a small helicopter can “probe many places that we can not go to by plane”. The expert also explains that Mars has some interesting things. The crater walls and other destinations will be interesting to study up close, while astronauts won’t be able to explore. In the future, helicopters could be an important asset for both robot and human exploration on the Red Planet, Mr. Zurbuchen said. However, as mentioned before, Mr. Zurbuchen said, there are many applications to this technology that are yet to be developed. Science breakthrough The deployment of the Ingenuity helicopter flight plan on Mars aims to demonstrate that humans can fly in the extremely low density, reduced gravity and extreme temperatures of the red planet. In addition, the amount of sunlight the planet receives is only half that of Earth; At night temperatures down to -90 degrees C cause electronic components to crack and freeze if left unprotected. While a mission on Mars is not an easy task, NASA is confident that this small helicopter can overcome the challenge. However, the first flight will be at low altitude and take place shortly. Members of the mission group said, Ingenuity (weighing 1.8 kg) is expected to fly no more than 3 meters above the floor of the Jezero crater on Mars. The helicopter will stay high for 40 seconds or so. However, even such a modest flight time would be an achievement. Because, Mars’ atmosphere is only 1% thicker of Earth. Aircraft generate lift by pushing air. However, according to Project Director Ingenuity – MiMi Aung, of the NASA Jet Propulsion Laboratory (JPL) in Southern California, on Mars, there are fewer molecules to propel. That disadvantage outweighs the benefit that helicopters get from Mars’ weaker gravity. So Ingenuity has to behave a little differently from its predecessors on Earth. Specifically, Ingenuity propellers are made of carbon fiber, made for Mars. They are particularly large compared to the overall 48 cm high helicopter. Each wing extends 1.2 m. Those propellers will spin at about 2,500 rpm to bring Ingenuity off the ground. This is much faster than that required by a 4lb motor. Besides, Mars is also a place where the cold is “piercing”. Perseverance measured the Red Planet’s nighttime temperature to minus 117.4 degrees F (minus 83 degrees C) on the surface of Jezero. So Ingenuity has a fireplace so it won’t freeze. Currently, it takes more than 15 minutes for an order to be sent from the control agency on Earth to Mars. Real-time operation with the joystick is therefore not an option. Flight orders must be sent in advance. However, that doesn’t mean Ingenuity is going to be in trouble. This helicopter will be able to do many tasks on its own. For example, Ingenuity can analyze photos captured by the downward-facing camera. From there, locate it. The images will be in black and white. Ingenuity is also capable of 13-megapixel color photography. There are a series of complicated devices that are inserted into the “small body” of Ingenuity, although the helicopter does not carry any scientific tools. Cameras, electrical systems, avionics systems, and communications equipment for data transfer to Perseverance were all introduced into Ingenuity. In fact, the size of devices like objects has made it impossible for many helicopter missions on Mars. Ms. Aung and her colleagues tested Ingenity extensively on Earth before launching. Ingenuity used to have to fly in a special chamber at the JPL – which simulates the conditions of the Red Planet. Thanks to that, Ingenuity has been doing well on the Jezero crater since its separation from Perseverance. Therefore, the scientists expressed confidence in Ingenuity’s mission. If successful, Ingenuity will fly again – up to 5 times in about a month. Ingenuity helicopters pave the way for future space exploration.

Most planets in the universe are not suitable for us to live in. With the current environment in the planets, imagine how, if we humans lived there, the body would change. Mars Gravity is lower on Mars than on Earth and it is further away from the Sun, so if we live on Mars, we will see less sunlight. Mars also lacks a protective magnetic field due to its thin atmosphere, everything there, including humans, is exposed to radiation. Occasionally, strong winds create dust storms that fly across the planet, and dust continues to settle for months to come. So if you go to live on Mars, you may be taller, stronger body to compensate for the poor gravity. You will have big eyes for better visibility when the Sun is too far away. In addition, the main pigment in your body changes from melanin to carotenoids (carrots, tomatoes and oranges). So your skin is likely to be orange. Jupiter Living on the surface of Jupiter is challenging because the planet has no real surface. It is purely air. However, this does not mean it is just a giant cloud suspended in space. If you travel through its atmosphere to deeper parts, the gas will become dense until it turns into a liquid. In a nutshell, Jupiter is an ocean layer made up of hydrogen instead of water. With such high pressure, extreme temperatures and liquid environments, humans would have to mimic creatures that live in deep water. We would be like animals with small legs and hard shells to protect the body from Jupiter’s radiation. Saturn Saturn is also a giant cloud of hydrogen and helium, with no soil or no wind. However, inside it is much denser and much smaller than Jupiter. Its iconic belts are made of countless ice particles, so nothing can live on this planet. The Saturn rings are innumerable ice particles. Saturn’s weight is too small, so it can float in a bath if there is a tub large enough to hold. The only way to get around in the dense mist of Saturn is to hover around like a jellyfish. Your body will not have a skeleton so that it cannot be crushed by the pressure. Mercury Life on Mercury is extremely difficult. This tiny planet is closest to the Sun, so the sunlight here is seven times bigger than Earth, no sunscreen can resist. Mercury’s temperature is extremely extreme, around 430 ° C during the day and -180 ° C at night. The planet is also prone to meteor shower and earthquakes. There is no atmosphere here to breathe. How must we change to accommodate Mercury? Meat and bones can never withstand the harsh conditions here. So to live in Mercury, our bodies must be made of something similar to the refractory metal, for example, titanium. There’s no need for a respiratory system, so your pretty metal face won’t have a nose. And your eyes will be like a thick sunglasses to protect them from the sun’s light. Venus If there’s a place that’s harder to live than Mercury, it’s definitely Venus. The temperature here is a whopping 471 ° C. The atmosphere is extremely thick, creating a greenhouse effect. The planet’s surface is very dry, there are many natural disasters such as volcanic eruptions, hurricane winds and lightning. The pressure here is like you are 1 mile underwater, giving you constant headaches. Unfortunately, the only thing that can exist on Venus is bacteria. Venus corrode everything, even metal, making it impossible for human spacecraft to stop here. Venus’s atmosphere contains phosphine, which is toxic to any organism that breathes oxygen, but is very beneficial for bacterial growth. Uranus, Neptune Frozen, dark and plagued by strong winds, Uranus and Neptune are mostly made up of cold liquids – methane, water and ammonia. They do not have a solid surface, and their atmospheres slowly mix with the water around the cores of other planets. Gravity is stronger here than on Earth and puts more pressure on everything. With such a strong gravity, the human body living here would have to be shorter and muscular, muscular, and thicker in skin to resist the cold. And for the liquid environment here, the best form to live in is a cosmic dolphin or manatee, making it easier to navigate around the planet. The Pluto Pluto is the planet farthest from the Sun, covered with ice and snow. Gravity is extremely weak and the atmosphere is fragile. The sun seen from Pluto is just a dot on the horizon, like the Moon to Earth, so there won’t be much light. However, scientists believe that there may be ocean water below Pluto’s surface. If you live on Pluto, your body needs antifreeze, like some insects and fish. Low gravity causes muscles and bones to shrink, the space between the vertebrae expands and makes us taller. Human posture will also change as the spine is not doing too much. So you can be tall, thin, and somewhat spiderman with flexible limbs and a curved spine.

Technician places the MOXIE device inside the Perseverance vessel in the laboratory in Pasadena, California, USA, March 2019. (Photo: AFP / VNA) After the Ingenuity mini helicopter made history by successfully making its first flight on another planet (Mars) a few days ago, the US Aviation and Space Agency’s Perseverance expedition ship ( NASA) continues to make a spectacular new mark when it first created oxygen on the “Red Planet.” NASA’s announcement on April 21 states that the Perseverance explorer has made history by successfully converting carbon dioxide from the Martian atmosphere into oxygen. This is the first time creating oxygen is done on another planet. “This is the first important step in converting carbon dioxide (CO2) into oxygen on Mars,” said Jim Reuter, NASA’s space technology mission executive vice president. The Mars experiment using local oxygen resources, called MOXIE, is a device the size of an automobile battery and is located inside, in front of the right side of the Perseverance. The device uses electrochemical methods to split carbon dioxide molecules, made up of one carbon atom and two oxygen atoms, and produces a carbon monoxide by-product. Manufactured by Massachusetts Institute of Technology (MIT), MOXIE is made of a heat-resistant material like a nickel alloy and is designed to withstand extreme temperatures up to 800 degrees Celsius. The device is coated with a thin layer of gold. so as not to radiate heat and harm the Perseverance vessel. On the first test run, MOXIE generated 5.4 grams of oxygen – enough for an astronaut to breathe easily for 10 minutes while still performing normal activities. Engineers will conduct more tests and find ways to increase oxygen production. By design, MOXIE can generate 10 grams of oxygen per hour. “MOXIE has a lot to do, but the results from this technology demonstration are promising as we move towards our goal of one day seeing humans on Mars,” said Jim Reuter. Tests for MOXIE will be divided into three phases. The first stage is to test and characterize the equipment. Stage two will evaluate the performance of MOXIE under a variety of atmospheric conditions. In the final phase, researchers will step up the operation of the equipment, which includes testing new operating modes or adding functionality. NASA expects the development of experimental instruments not only to help generate oxygen for astronauts in the future, but also to help generate large amounts of oxygen to be used as rocket launchers for the return journey. Not transported from Earth. According to MIT engineer Michael Hecht, a one-ton version of MOXIE can generate about 25 tons of oxygen needed for a rocket to take off from Mars. Production of oxygen from the atmosphere is 96% carbon dioxide’s Mars It may be a more viable option than extracting subsurface magnetic ice and electrolysis to produce oxygen. Ms. Trudy Kortes – Technology Demonstration Director NASA “MOXIE is not only the first instrument of oxygen production in another world, but the first technology of its kind that helps future missions use elements of another world environment, also known as on-premises resource use. ” Expedition ship Perseverance landed on Mars on February 18, on a mission to search for signs of microbial life on the “Red Planet.” In the coming years, the Perseverance ship aims to collect 30 soil and rock samples to send back to Earth (estimated around 2030) for analysis.

Elon Musk left barefoot while sharing with Peter Diamandis about his plans to return to the moon. “Exploring Mars is not an outlet for the rich. The adventurer will probably face death so there are only volunteers and absolutely no coercion ”. Last week, SpaceX won a major order from NASA and became the only supplier designated for lunar landings. Before that, SpaceX plans to send humans to Mars by 2024 and establish a human colony by 2050. SpaceX has also completed the mission of sending four astronauts into space using a Falcon rocket. 9 “used”. The International Space Station (ISS), where NASA and the Global Space Administration have technology that sustains life. But this is different from NASA’s Enhanced Life Support (ALS) program. In other words, although the International Space Station has many different functions, such as water recycling, in Musk’s Mars plan, humans need support in long life instead of taking turns. from earth every few months and frequent short trips. If the Mars colonization program can go on and take root, it would mean providing food, shelter, medical services and ensuring the spiritual well-being of the entire population. Humanity to land on the moon in 2024 is possible It’s been 51 years since Armstrong first landed on the moon in 1969. On April 17, NASA confirmed Elon Musk’s SpaceX selection as a service provider for the moon return plan under contract. monopoly worth 2.7 billion USD. For Elon Musk, that would be another great achievement for SpaceX. As for NASA, this is an important step in pushing the plan to land on the moon repeatedly delayed. Musk believes SpaceX can help NASA achieve this ambitious goal by 2024. At 18:49:02 on April 23, Hanoi time, SpaceX successfully launched the old Crew Dragon spacecraft with the Falcon 9 rocket bringing 4 astronauts into space and they will arrive at the space station after 23 hours. . This is SpaceX’s second commercial launch and the Crew Dragon spacecraft’s fourth launch mission. So far, SpaceX has carried out a total of three manned ship launch missions, including the manned spacecraft DM-2 on May 30, 2020, Crew-1 on November 16, 2020, and Crew- 2 on April 23, 2021. A total of 10 astronauts were sent into space in three launches. Shortly after SpaceX successfully launched the Crew-2 onto the International Space Station, Musk said, “I think a return to the moon can be done.” “It has been almost half a century since man last set foot on the moon. This period is too long. We need to go back there and build a permanent base on the moon. Then build a city on Mars, become an aerospace civilization, a species of multiple planets, “this billionaire confirmed. “Martian” Elon Musk: Dreaming of the galaxy, spreading money into space Elon Musk not only has a large brain, but also has a “big mouth”. In an interview with Business Insider, when asked when humans appeared on Mars, Musk’s answer was, “Maybe six years later, or four years later. As for me, it will be about 2 or 3 years later ”. In fact, the owner of SpaceX has a special passion for Mars and founded Life to Mars to encourage activities to explore the planet. “If you were buried somewhere, born on Earth, and died on Mars is a wonderful thing,” Musk said. Elon Musk has a special passion for Mars “Eventually, life will spread across the entire solar system, and then cross our solar system into other star systems. If not, we will stay on Earth forever until extinction occurs. One of Elon Musk’s most important goals is to help humanity become an interplanetary species and be able to leap from earth civilization to space civilization, so SpaceX is so important. Also on Friday’s live broadcast, Musk announced he would give inventors a $ 100 million bounty for figuring out how to combat global warming by removing carbon dioxide from the atmosphere. book or ocean. This is “the greatest prize in history” and lasted for four years. “The sun will get bigger and bigger, evaporating the ocean. So, to some extent, we should do something better. Mars is a real planet, so we can create a civilization there, ”hopes Elon Musk.

Photographs on Mars taken by a rover vehicle called Perseverance have stirred the Internet community since NASA’s latest robotic technology landed on the “Red Planet” in February 2018. Despite being two different planets, Earth and Mars still have similarities. Some pictures on Mars look quite similar to those of Earth’s Atacama Desert, Chile. NASA has spent time and money exploring this Mars-like land. NASA’s ARADS team is experimenting with the original rover on Mars in the Atacama Desert in Chile in 2018. Photo: NASA. “You can argue that the Dry Valleys Valley in Antarctica or the northern central Atacama is the hottest place on Earth. However, some places in Atacama only rain every 20 years, even 100 years later, “said Brian Glass, a researcher at Atacama Rover (ARADS). This research uses the Atacama Desert to test field tools and techniques for future missions to Mars. Because the Atacama Desert resembles a dead and deserted land, NASA investigated and found it almost a “copy” of Mars. They have been testing rovers since 1997. The newest rover uses original tools, they try to find and detect life here. “Because if you can’t find life in one of the bariest places on Earth, don’t think about going to Mars looking for it,” explained Glass. The Atacama Desert stretches for more than 1,600 km in the northern half of Chile between the Pacific Ocean and the Andes mountains. Glass says that to know how barren places like the Atacama Desert are, think about organic cues (such as life) to ambient noise. “The signal in the Mojave desert and remote parts of the US is still quite loud. You can still see shrubs, cacti, microorganisms, scorpions, insects; there is still an ecosystem there, ”said investigator Glass. Like Mars, the Atacama Desert has a harsh terrain with vast salt flats and towering volcanoes, including the most active mountain on Earth. Here, the night sky is very dark and has the largest astronomical observatories in the world. NASA investigated and found that this place is almost a “copy” of Mars. Photo: Mark Johanson. The driest place on Earth When scientists say Atacama is the driest place on Earth, they are referring to Yungay town. This town is about 88 km from the city of Antofagasta, NASA is doing research in this area. According to Mr. Glass, Yungay is a long valley with both sides of the hill being eroded by the wind. Land in Yungay is brown and quite barren, with no signs of life. In Yungay town there is a hand-carved statue of nearly 11 meters high. This statue, called Mano del Desierto, was placed near the town by Chilean artist Mario Irarrázabal in 1992. Although Yungay has long been considered the driest place in Atacama, recent research indicates that the title actually belongs to the Maria Elena South region, located about 273 km north of the nitrate mining town. Neither site has any facilities or attractions, but they are key points to the Atacama’s “emptiness” and similarities with Mars. Furthermore, because the McMurdo Dry Valleys Valley in Antarctica is particularly hard to reach, many scientists believe the valley is even drier. A hand-shaped sculpture of nearly 11 meters high is called the Mano del Desierto. Volcanoes and geysers While Mars is the “home” of the tallest volcano in the solar system, Olympus Mons, the Atacama Desert contains the most active volcano on Earth, the Ojos del Salado. This gray-brown mountain is about 7,000 meters above sea level and is the second highest peak in the western hemisphere after Aconcagua in Argentina. However, this mountain’s permanent crater lake is said to be the tallest lake in the world. “When you look at this impressive mountain range, surrounded by volcanoes over 6,000 meters high, you will find yourself very small,” said Ercio Mettifogo, the adventure tour manager Puna de Atacama. To climb the top of Ojos del Salado, climbers do not need a lot of climbing techniques, although the altitude of the mountain is not small, but strong winds on the mountain up to 119 km / h and -29 degrees Celsius is definitely a challenge for surname. Most trekking takes place between November and April, the climbing period lasts 8 days for the climbers and 12 days for the amateur climbers. According to Mr. Mettifogo, Atacama Altiplano is often compared to the Tibetan plateau. The area near Mount Ojos del Salado, home to about 17 mountains over 6,000 meters high, has become a hub for adventure tourism. Farther north, near the tourist town of San Pedro de Atacama, another geothermal wonder of Atacama is the El Tatio geyser, dubbed the Yellowstone mini national park with 80 geysers of geysers that boil and smoke. raised suspicion. In the panorama of snow-capped volcanoes, El Tatio is the widest geyser region in the southern hemisphere and the tallest on Earth at 4,300 m altitude. El Tatio geysers are known as Yellowstone mini national park with 80 geysers of geysers boiling and smoke rising. Photo: Shutterstock. Salt beach and flamingos Much of the Atacama desert is barren like on Mars, but this land stands out with its beautiful salt-shoals, known as salares , with saltwater currents nourishing the life of a number of animals, including flamingos. There are many species of flamingos, including the rare Andes with yellow feet and black point wings, the smaller James flamingo with brick red feet and a bright yellow beak. In addition, the pinkest flamingo of all species is the Chilean flamingo. Chilean flamingos live in popularity along South America, stretching from Argentina to Ecuador. Pink-colored birds are easily found in Andes parks such as Los Flamencos National Reserve, near San Pedro and Nevado Tres Cruces National Park, near the city of Copiapó. “The salt beaches are also famous for the colorful lagoons,” said Gabriel Rojas of Turismo Atacamensis, guide taking tourists swimming in the turquoise lagoon in Salar de Pedernales, north of Nevado Tres Cruces National Park . There are also blood red, navy and emerald green pools in Pedernales, all connected on a three kilometer walking trail. Some scientists believe that, if humans do find signs of life on Mars, it would be historic salt ponds that formed in places like the Gale Crater and are believed to resemble what is found in the Altiplano of South America.

The clearest sky in the world The Atacama Desert is not only NASA’s test site for future Mars missions, but also where some of the most advanced planetary observations have been made on Earth. Northern Chile is home to about 70% of the facilities for Astronomy worldwide. The biggest projects in the 2020s including the Giant Magellan Telescope and the Extremely Large Telescope will all be set on bare hills over the next few years. “When night falls, silence and darkness will take over, it is unaffected by the lights and noise of the city, the place will turn into a path to heaven that makes you feel like can touch the universe, ”said Cristóbal Vergara, founder of Turismo Tembeta, a company that manages stargazing tours from the city of La Serena. The Elqui Valley, located on the southern edge of the Atacama Desert, has become a major center not only for scientists but also for stargazing lovers. “Along the mountains there is still mist from the Pacific Ocean, forming a few small clouds and making the sky clear,” Vergara added. To cater to your stargazing needs, there are nearly a dozen observatories near the Vicunã tourist center that are open daily for tourists wishing to see the stars in the hope of being able to get a closer look at Jackson Pollock’s sky. Many research facilities such as the Gemini South, Cerro Tololo, La Silla and Las Campanas are also open on weekends for visitors to visit. In 2015, the Elqui valley was named the world’s first International Night Sky Mecca. Thanks to that, the inns have transparent comfort to watch the stars begin to sprout like mushrooms, visitors can comfortably sleep under a starry sky.

Mr. Vergara said that the best part about stargazing here is that visitors are staring at “a place with great discoveries, technological advances and new astronomical discoveries that can help the future. hybrid of humanity ”. Atacama may not be as cold, harsh, or “alien” as Mars, but this land shows a “clone” of Mars right on Earth. Coming here to visit helps visitors to experience the feeling of traveling on Mars.

The Mars expedition can last at least 3 years. Brain structure effect The missions that bring humans to Mars are considered to be a major leap in space exploration. NASA has a goal of sending people to Mars by 2030. However, a trip to Mars is not the same as taking a flight to New York. Because space is an extremely harsh environment for human life, including the lack of gravity and harmful radiation, as well as isolation and lack of day or night. Missions to Mars will require more astronauts physically and mentally than man-made journeys in 60 years of space exploration. A flight to Mars and back will take about 14 months. Meanwhile, the actual exploration mission will last at least 3 years. Maintaining good cognition and effective teamwork are the prerequisites for the safe and successful outcomes of these tasks. However, a new study published in the journal Frontiers of Physiology found that the lack of gravity during such missions can have negative effects on cognitive skills, as well as emotions. of the astronauts. Since the first space missions, it is clear that exposure to a “microgravity” (weightless) environment leads to drastic changes in the human body. This includes changes in the cardiovascular, skeletal and nervous systems. On Earth, we discover gravity with the aid of our eyesight and various organs, including those in the inner ear. When our heads are upright, the hearing stones in the vestibular system are perfectly balanced by a viscous liquid. However, as we move the head, gravity causes the liquid to move with it. This activates signals to the brain that our heads have changed positions. In space, this process is no longer active. Space flight can even bring about adverse changes to the brain structure of astronauts. Changes in brain structure were observed in astronauts after they returned from the International Space Station (ISS). The scientists found that in these astronauts, the brain physically moves inside the skull and reduces the ability to connect between regions of the brain layer, the cortex and the inner regions. Emotional perception is extremely important to astronauts. Difficulty recognizing other people’s feelings The acumen and quick thinking of astronauts are essential elements in a space mission. So is the ability to accurately “read” each other’s emotional expressions. Because, they have to spend a lot of time sitting together in a small space. Therefore, it is recommended that space agencies consider training, as well as psychological support for astronauts before the flight, to minimize this risk. To date, how these changes affect behavior is not concretely understood. However, scientists are getting closer to the answer. Because, they realize, astronauts can be disoriented, disturbed perception, balance disorders and motion sickness. However, such findings are often made based on a small group of people. New NASA-backed research has explored the effect of microgravity on cognitive performance. However, 24 study participants were not sent to space. Instead, the scientists asked these people to lie in bed. This is because the effect of a certain type of bed rest is similar to that of microgravity. Therefore, scientists have repeatedly applied this method in research. When we are upright, the body and hearing stones in the vestibular system are in the same direction as gravity. Meanwhile, the moment of lying down, the body and hearing stones are perpendicular to each other. Therefore, study participants had to lie on their back at an angle of 6 degrees, their head lower than their body. They were asked not to change their position for almost two months. At the same time, the participants also routinely perform a series of cognitive missions designed for astronauts and related to space flight. As a result, it helps to evaluate their spatial orientation, memory, risk-taking behavior and understanding of their feelings about others. The results showed that the cognitive speed of these people slowed a bit but remained reliable in tasks related to sensory and motor skills. This seems to be consistent with reported changes in brain tissue density across “motor sensory regions”. These are the main motor and sensory regions of the brain, helping to process sensory input and movement, observed after a person has flown into space. Participants also had difficulty recognizing emotions when looking at people’s faces. Adjusting to changes in gravity takes time and effort. While performance on most cognitive tasks initially decreased, after about 60 days, the participants remained unchanged throughout the test. However, their ability to perceive emotions continued to deteriorate. In fact, the participants became inclined toward negative emotions. They are more likely to recognize another person’s expression as angry and have a hard time explaining how happy or normal the other person is.

The entire NASA Jet Propulsion Laboratory (JPL) in the state of California burst out loud, clapping. After more than 10 days of delay, the Ingenuity helicopter weighing only 1.8 kg, worth $ 85 million of NASA, took off successfully on Mars. This victory is likened to NASA as the living moment of the Wright brothers (USA) who successfully made the first flight on Earth in 1903. NASA’s Jet Propulsion Laboratory (JPL) tweeted immediately after Ingenuity’s success: “Perseverance has brought us to Mars. And Ingenuity takes us higher.” “. NASA’s Mission Control Room at (JPL) received a 14-minute delay in success signal because of a distance of 289 million kilometers from Mars. Photo: NASA The moment in which the Mission Control room was delighted to hear that Ingenuity had successfully flown on Mars. Photo: Reuters “Now, 118 years after the Wright brothers successfully made the first flight on our planet in the 20th century, the Ingenuity helicopter has succeeded in performing this amazing feat in the world. another – the Red Planet – in the 21st century “- NASA Deputy Science Director Thomas Zurbuchen said. At a distance of 289 million km (from Earth to Mars), the Ingenuity Mars helicopter has done a miracle, unprecedented in history: Automatically refuel from the Sun, automatically fly to a maximum prescribed height of 3 meters and maintain that altitude stable for 30 seconds, then a gentle landing on the surface of the Red Planet. The whole process took 39.1 seconds. 39.1 seconds is only two-thirds of the time of a minute. The time is extremely short but is a wonderful fruit for the efforts of thousands of minds to contribute to Mars Mission 2020 of NASA. It took NASA nearly a decade to prepare for this feat. SURVIVAL WITH SUCKS Dr. Daniel Brown, an astronomy expert at Nottingham Trent University (UK), described sending something flying to Mars as a ‘staggering feat’. The biggest challenge of the Ingenuity engineering team is the flying environment on Mars: – First money. So far, no one (human) has set foot on Mars. All scientists know is simulate that environment through data and images transmitted by NASA’s self-propelled explorer ship back to Earth. – Second, the Mars environment is known for its harshness: The difference in temperature between day and night can “kill” human machines, in particular, Ingenuity helicopters are too small, too light (this is required technical conditions for test flight). Not to mention, the Red Planet does not have a magnetic field, the gravity one third that of Earth; and the atmosphere is extremely thin, only 1% of the pressure on the surface of our planet.

Therefore, the blades of Ingenuity reach 2,500 rpm. Each propeller on the Ingenuity is made of a 57-gram composite material that powers a chopper body the size of a tissue box! OPEN THE WAY TO DISCOVER THE NEW SKY To further mark the link between the Martian Ingenuity helicopter and the Wright brothers ‘maiden flight, NASA confirmed it had named the first Mars airport (where the Ingenuity helicopter took off) as’ Wright Brothers. Field ‘. “We don’t know exactly where Ingenuity will lead us, but today’s results show that the sky – at least on Mars – may not be the limit,” said NASA Administrator Steve Jurczyk. . Just as the Wright Brothers’ flight ushered in human exploration of the sky on Earth, Ingenuity’s mission has sparked a new wave of exciting projects, poised to take the discovery of distant world to a new level. In 2027, NASA plans to launch Dragonfly mission his highly anticipated, in which a helicopter will fly over the sky of Saturn’s moon Titan. Other missions to explore distant atmospheres – such as Venus’s cloud survey mission – may soon emerge. THE MISSION OF INGENUITY NOT STOP HERE … The NASA team plans to have Ingenuity more test flights in the next few days, with up to five bolder flights over the next 30 days assuming each is successful.

Mr. Scott Kelly while living on the ISS Station. Photo: NYT In a study published in the journal Circulation on March 29, scientists found that during 340 days in space, Mr. Kelly’s heart was reduced in size even though he still exercised hard for 6 days. week. Luckily, the smaller heart did not seem to have any effect on the health of Mr. Kelly when he returned to Earth in 2016. This finding has added to the list of the types of transformations the human body has to undergo in an unstable environment of gravity. Astronauts also tend to have head edema, eyeballs crushing, leg shrinkage, and bones become more brittle. According to the New York Times, Dr. Benjamin D. Levine, study author and professor of internal medicine at the Southwestern Medical Center at the University of Texas (USA), said: “Kelly’s heart has changed to adapts to reduced gravity conditions. It does not have any dysfunction. He is still healthy. Without gravity, the heart doesn’t need to pump blood fully, and like any other muscle, it is altered by decreasing the intensity of the activity. For Mr. Scott Kelly, the shrinking phenomenon still occurs regardless of the regular exercise 6 days / week on the ISS. This regimen has been shown to be effective in reducing brittle bones and reducing muscle mass. After 340 days in space, Mr. Kelly’s heart weight dropped by about 27%, from 190 grams to 140 grams. Mr. Kelly shared that his body also underwent some other changes, such as bone loss, and these phenomena have almost returned to normal. However, the miniature heart phenomenon could be a concern for future missions to Mars. Based on the experiences of Mr. Kelly and other astronauts on the ISS, Dr. Levine thinks that the upcoming visitors to Mars will remain in good health. However, problems can arise if an astronaut is injured, becomes ill and cannot exercise, or if the exercise equipment is damaged. With weaker hearts, they can be dizzy and faint as they step onto the red planet after months of weightless travel. Swimmer Benoit Lecomte. Photo: CNN In the study, Levine and his colleagues compared the heart of astronaut Scot Kelly to that of long-distance swimmer Benoit Lecomte, when he tried to swim across the Pacific in 2018. The buoyancy in the water has the same impact on the body as the weightless environment. Lecomte athletes spend most of the day in the horizontal position: 8 hours of swimming and 8 hours sleeping on a support boat. Scientists think that extended swimming hours will be strenuous enough to maintain Mr. Lecomte’s heart size. But instead, it shrinks at a rate nearly as fast as Mr. Kelly’s time in space. After more than 159 days, the Lecomte athlete abandoned the plan after swimming two thirds of the planned 5,650 miles because the boat was destroyed by a storm. Through ultrasound, it was found that his left ventricle was about 28 grams lighter. The left ventricle is the heart’s largest and most powerful chamber, pumping blood to the aorta and throughout the body. Dr. Levine expressed surprise when she learned the results. “I thought his heart would get bigger. That is a huge amount of training ”. In an interview, Benoit Lecomte estimated his heart rate could be below 100 while swimming, and described the intensity of long-distance swimming as walking briskly, or running very slowly. Now, the US Aerospace Agency (NASA) can design better training programs for astronauts. In space, Mr. Scott Kelly has been exercising 6 days a week, 30-40 minutes walking on the treadmill or cycling. In addition, he also uses a resistance machine to lift weights. “This practice regime is quite strenuous. I have to push weights quite hard. The weight is definitely heavier than I can lift at home, ”said Kelly, now retired at NASA, in an interview. Dr. Benjamin D. Levine said there is another study to track the hearts of 13 astronauts before and after 6 months on the space station. This unpublished study will provide a broader amount of data.

Episode 12.

Just like in Greece, the process of birth, development and completion of the republic was associated with a long and fierce class struggle. Until the 3rd century BC, the state reached a complete level. The aristocratic Republic of Rome consisted of the following bodies:

1.Garitan Congress: The Congress of Military Units and also the Congress of the People, the highest authority of the Roman State, consists of 193 military units. The Franciscan congress is held twice a year, in Mac-fiber Square (Mars the god of war). This congress has the powers and duties of electing generals annually, electing high-ranking state officials, deciding domestic and foreign affairs of the country, issues of war and peace.

2. Consul: Is the head of state, is a high-ranking official in the ranks of Roman officials. In Rome there were usually two consuls. This position was elected by the Congress of Zion, selected from among the great nobles, for a one-year term. The two consuls had great military and civil power, the commander-in-chief of the army, and the power to convene the Senate Congress and the Scottish Congress.

3. Senate: Inherent from the monarchy, including powerful aristocrats. It was an office of the gentile clan, had between 300 and 600 people, and by the end of the republic had up to 900 people. It was a quasi-permanent organ of the Franciscan Congress, great power at times overwhelming that of the Xenturi Congress. The Senate has the power to approve the appointment of high-ranking officials of the Warsaw Congress, to pass congress resolutions, to administer state property, to interpret laws, to recommend building new rule. The Senate also has the power to formulate and direct domestic and foreign policy, the right to appoint a court, and order preliminary investigations of cases. The Senate also oversees the Roman religious affairs.

4. Consular Council: An executive body, elected annually by the Geneva Congress, consisting of high-ranking officials in the ranks of mandarins. This agency has the power to manage all state affairs, oversee law enforcement, has the power to fire subordinate bureaucrats, and to command the military.

5. Council of Judges: A council of seven people, elected by the annual Congress of Zion. This is the jury of the Roman court, specializing in criminal and civil cases. In addition, when the Consular Council is absent, the Council of Judges performs the duties of the Consular Council.

6. Supervisory Institute: Also known as the important people, is an important agency in the Roman state apparatus. This House has the right to suspend the implementation of all decisions of the Senate and of the Franciscan Congress if those decisions harm the interests of the people. The Institute also has the power to arrest public officials suspected of crimes.

In addition, there were many different high-ranking officials in Rome. All are responsible for their actions, if they commit crimes, they will be prosecuted before the law.

The clergy plays an important role in the political life and in the state apparatus. From the founding of the country until before 313 BC, Rome followed polytheism due to the religious influence of the Greeks. Accordingly, the god Jupiter (Jupiter) is considered the supreme god, creator and ruler of the universe. Juno) in charge of marriage, family, Venus (Venus), goddess of beauty and love, Mac-fiber (Mars): in charge of war, and so on.

But in 63 BC, Rome conquered the Palestinian region. So Judaism and later Christianity entered Rome. By AD 314, the Roman slave owner officially adopted Christianity as the state religion.

In short, the Roman State was a slave-headed aristocratic republic, in which the power of the gentile clan was still very strong. So in the class struggle, the popular posture and the industrial and commercial aristocracy were not capable of a complete victory over the gentile nobility, leading to in the 1st century BC, the generals, the gentlemen. the clan overthrew the republic again, established a dictatorship and monarchy.

In 82 BC, Xila established a dictatorship and declared dictatorship for life. In 46 BC, after defeating two political opponents, Crassals, Pom-pe (Pompey), Judi-ut Caesar (Julius Caesar) established a military dictatorship. But in 44 BC, Caesar was stabbed to death by an enemy while presiding over the Senate meeting. Shortly thereafter, all authority in Rome was in the hands of Ogre-via-buttons (Octavinus). In the year 27 B.C., Oc-ta-via-knot received the title Ogut, meaning the one of dignity, that is, Snail-ta-node, became Emperor. The republic collapsed and Rome entered a monarchy.

The change in Roman state institutions was also in the force correlation of the class struggle. At that time, due to the invasion, the Roman land expanded, the economic power of the land slave owner was strong, the Roman colony existed to popularize the form of large estate, a great estate to use. thousand of labor slaves. The strong economic power made the agricultural aristocrats to win the political struggle, to establish a dictatorship and monarchy.

Slaves in the 1st century BC together rose up to fight against the brutal exploitation of the slave master, such as the Nazi-cut revolt (Spartacus 73-71 BC). Although the rebellion was fiercely suppressed by the Roman slave owner, thousands of slaves were killed and their heads were piled on the great road from Rome to the periphery. However, slavery and the Roman state after that great uprising also collapsed. Besides the enslaved insurrection, there is also the struggle movement of peoples invaded and enslaved for self-liberation. To have the power to suppress slaves and the colonial people, Rome needed a strong government: dictatorship and monarchy.

Following Snail-node, Rome underwent emperors such as Ciligua – the insane king, Co-Diuu-fiber (Claudius) – the weak king, Nero– the greatest tyrant in the ancient history of the world. He slaughtered tens of thousands of Christians, killed wives and children, killed his brother, murdered the famous idealist and philosopher Sehemiah (Seneca) and eventually killed the Queen Queen. , the mother of y.

In 476, the Roman Empire perished. Europe ended slavery and entered a new socio-economic form: Feudalism was born during the dissolution and collapse of the giant Roman empire.

II.The Law

1. Roman law of the republic: The law of 12 pounds

Due to the struggle movement of the common people and the master of slaves and the mercenaries against the arbitrary manipulation of the judiciary in the judiciary, in 450 BC, a committee of 5 common people and 5 nobles was formed to write draft a written law. By 449 BC, this commission had finished drafting the law. The code is engraved on 12 bronze planks (the number 12 is the lucky number from the European point of view) and is placed in a public place for all to see, so the code is called the “Rule of 12”.

The 12-pound law clearly reflects the economic and social relations of early Rome in the republic. The main content of this law is to protect the property rights of wealthy slave owners. The law stipulates that anyone who trespasses on other people’s property such as theft, crop damage, home trespassing (burning a house) will be executed. If a thief enters a house, if he is killed, it is legal to kill the person.

The law sets out the cruel penalties for debtor. If the debtor fails to pay the debt on time, the court allows the creditor to arrest the debtor. During the 60 days of detention, the debtor was taken to the square three times on the day of the fair for the court to judge. After 60 days of detention, still unable to pay the debt, the creditor took the debtor out of the way. If you’re unlucky and still can’t pay the debt, the debtor can either be killed or sold overseas. Where the debtor owes many creditors and cannot repay, the creditors have the right to hash the debtor into pieces.

In terms of marriage and family, a man’s power is absolute. The husband manages the property. When a daughter gets married, it depends on her husband and father-in-law. The father has the right to sell his child as a slave. If sold for the third time, the son will be free from the bonds of the father. The law allows fathers to strip children of inheritance. The dying person is left with property for anyone. In order to protect the rights of an heir under the will, Zionariah has the authority to oversee the distribution of that property.

The 12-table law has a number of provisions on civil proceedings, but these provisions are cumbersome, cause difficulties and troubles in the process of adjudication and do not create favorable conditions for commodity economy. develope.

2. Late Roman republican law

The last period of the republic started from the 3rd century BC until the destruction of the republic (1st century BC). That was the peak period of the Roman empire. The territory covered from the West to the East, the commodity economy was thrived, the agriculture of a large estate was strong. All of them are the basis for the development of the law and vice versa, the economy and social relations themselves also need a comprehensive legal system to serve that infrastructure itself.

In the late republic, the sources of Roman law included:

– The decisions of the consuls. The consular documents were later codified by the famous jurists in the East Roman imperial advisory council and submitted to the emperors for application.

– Decisions of a powerful agency like the Senate.

– The court decisions: sometimes the judgment is just using customary law and it becomes the source of law.

– The decisions of the governor of the provinces.

– Legal practices: Ethnic customs in localities are raised into legal norm by the state.

– The works and works of Roman jurists while summarizing, summarizing and codifying the law.

+ About ownership: Roman law introduces the concept of ownership. It is the absolute right of use and disposition over that property. But the owner is still restricted by law, or by coercion by the state. For example the state wants to let a canal carry water through the land of the owner, who is forced to accept, etc.

The person entitled to possession may use the benefits brought about by the land and must pay the land rent to the owner. More specifically, possession means the right to rent the property of others for use (renting land, renting shops, etc.).
