4 astronauts returning aboard Space X’s Crew Dragon spacecraft from the International Space Station crashed safely in the Gulf of Mexico, near Panama City at 2:56 a.m. on May 2 (US time). ABCNews reported that the ship left the space station at 20:35 on May 1 after bad weather at the place fell, causing the crew to delay their return twice. But upon landing on target, the spacecraft marked the first night-time fall of an American crew flight in 53 years. The last time was the Moon mission aboard NASA’s Apollo 8 on December 27, 1968. “Dragon, on behalf of NASA and SpaceX, we welcome you back to Earth. For those of you who study in our regular pilot program, you’ve earned 68 million miles (about 109 million kilometers).” on this trip, “a SpaceX crew operations and resource engineer told the Crew-1 astronauts after the spacecraft crashed. “It’s good to be back on Earth,” replied NASA astronaut Mike Hopkins, Crew-1 mission commander. Crew Dragon ship was launched from November 2020. Photo: NASA. Crew-1 marks SpaceX’s second crew flight to the space station and the first to last in six months. The ship was launched into orbit on November 15, 2020. Before that, in May 2020, a test flight of Crew Dragon was also made and lasted for 2 months, bringing 2 astronauts to the international space station. Although SpaceX’s third crew mission has already kicked off, today’s return marks the second crew’s success for the show. That third flight, known as Crew-2, won’t land until later this year. According to information from ABCNews, the Crew Dragon spacecraft has been nicknamed Resilience by astronauts. In addition to captain Mike Hopkins, the ship also carries other NASA astronauts Victor Glover and Shannon Walker and astronaut Soichi Noguchi of the Japan Aviation Exploration Agency (JAXA). Steve Stitch, NASA’s Commercial Crew Program Manager said in live commentary: “Certified vehicles land during the day or at night, so there is no problem with the vehicle itself. And we practiced with recovery groups to land during the day or at night. Steve Stitch added that the process went smoother compared to the recovery of the Demo-2 crew back in August 2020, when NASA astronauts Doug Hurley and Bob Behnken met a small private fleet. . This time, SpaceX and the Coast Guard have tweaked safety procedures to ensure no civilians get too close to the compartment, in case it leaks fuel. “All four crew members are doing very well. You rarely wake up on the space station and go to bed in Houston … Orbital mechanics and weather don’t always work well, but today.” now they have done so, “NASA Flight Manager Holly Ridings said at a press conference after the Crew Dragon landed safely. NASA’s director of human exploration, Kathy Lueder, recounted the radio station’s moment of silence as the Crew Dragon plunged through Earth’s atmosphere: “Astronauts are only anxious when experiencing a blackout – And it’s nice to hear Mike’s voice “… Four astronauts escaped from the hold with the help of medical staff, before returning to shore to catch a NASA plane back to the agency’s headquarters in Houston, Texas. 4 astronauts (from left to right): Shannon Walker, Victor Glover, Mike Hopkins and Soichi Noguchib inside the Crew Dragon. Photo: NASA According to CNN’s information, since leaving Florida in November last year, four astronauts Mike Hopkins, Victor Glover, Shannon Walker and Soichi Noguchi have had 167 days on the International Space Station – laboratory. The scientific experiment orbits the Earth 250 miles above Earth, which has been home to international crews of astronauts for more than two decades. The return of the four astronauts was originally scheduled for April 28, but was delayed due to strong winds in the area. Crew Dragon, also known as Resilience, is SpaceX’s second spaceship. The ship’s resilience broke the record for the longest serving US spacecraft ever docked on the International Space Station and surpassed the 84-day record of the Skylab 4 crew in 1974. Crew Dragon’s first landing took place in August 2020 on a Demo-2 mission, bringing NASA astronauts Bob Behnken and Doug Hurley back from space after a two-month test mission. Before the landing, the second crew of NASA astronauts Shane Kimbrough and Megan McArthur, astronaut JAXA Akihiko Hoshide and astronaut Thomas Pesquet of the European Space Agency were also launched to the Space Station. international post. That means crew 1 has a period of 1 week overlapping in orbit with crew 2. The second quartet of Shane Kimbrough, Megan McArthur, Akihiko Hoshide and Thomas Pesquet will remain in orbit until fall, when the 3rd crew enters space to take their place. Support crews were immediately present around the Crew Dragon vessel area that landed in the Gulf of Mexico early May 2 morning. Photo: NASA The first commercial spaceship SpaceX is one of two commercial companies contracted with NASA to fly astronauts in space. Space X’s Crew Dragon spacecraft can carry up to 7 astronauts and Cargo Dragon; was designed to be launched from the top of the Falcon 9 Block 5 rocket and returned to Earth via a crash into the sea. Unlike its predecessors, this spacecraft can be attached to the International Space Station instead of being anchored. Crew Dragon is equipped with an integrated launch escape system (LES) capable of accelerating a spacecraft from an emergency launch missile with an acceleration of 11.8 m / s2 (39 ft / s2), made using a set of four side-mounted thrusters with two SuperDraco engines on each side. The spacecraft has redesigned solar panels and revised outer mold lines compared to the original Dragon, and also has new aircraft computers and avionics systems. As of March 2020, four Crew Dragon spacecraft have been produced. Crew Dragon serves as one of two spacecraft slated to transport crews to and from the International Space Station under NASA’s Commercial Crew Program, the other being the Boeing CST-100 Starliner. . It is also expected to be used in US space travel company Space Adventures flights and transporting tourists to and from Axiom Space’s planned space station. Crew Dragon’s first drone test flight took place in March 2019, and the first crewed flight with astronauts Robert Behnken and Douglas Hurley took place in May 2020. The two astronauts Victor Glover, Mike Hopkins in the Crew Dragon. Photo: NASA This test flight marks the first time that a private company has launched a crewed orbital spacecraft. Cargo Dragon is expected to deliver cargo to the International Space Station under a Commercial Supply-2 Service contract with NASA, along with Northrop Grumman Innovation Systems’ Cygnus spacecraft and Sierra Nevada Corporation’s Dream Chaser spacecraft. . Cargo Dragon’s first flight is launched in December 2020. On November 10, 2020, the Crew Dragon, comprising the Falcon 9 missile and related ground systems, was fully certified by NASA as the first commercial spacecraft system in history to be capable of maneuvering. transfer people to and from the International Space Station. Initially, the company intended to let Crew Dragon land on land using the LES engine, with parachutes and ocean falls as options available in case of the incident, a Space X representative told reporters. Launch is canceled. Precise landing on water with a parachute has been proposed to NASA as Crew Dragon’s “method of returning to the atmosphere and fundamentally restoring the first few flights”. The forced landing was subsequently canceled, making parachuting the only option. By 2011, Paragon Space Development Corporation had been supporting the development of the Crew Dragon life support system. In 2012, SpaceX was in talks with Orbital Outfitters about developing space suits to wear during launch and return to the atmosphere. Each crew member wears their own custom fitted space suit. The suit is primarily designed for use inside the Dragon, and in the case of the fast depressurization cabin, this suit may protect crew members. The suit can also cool astronauts during normal flight. At a NASA press conference on May 18, 2012, SpaceX confirmed their target launch price for the Crew flights to be $ 160 million, equivalent to about $ 23 million per seat capacity. Crew up to 7 people on board and NASA orders at least 4 Dragon Crew flights per year. This contrasts with the 2014 Soyuz launch price of $ 76 million per seat for NASA astronauts. The design of the Crew Dragon spacecraft was officially announced on May 29, 2014, during a press event at SpaceX headquarters in Hawthorne, California. In October 2014, NASA selected the Crew Dragon spacecraft as one of the candidates to bring American astronauts to the International Space Station, according to NASA’s Commercial Crew program.

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.

Illustration. (Source: space.com) According to the Vietnam News Agency reporter in Tokyo, Japan in 2030 will launch a rocket with propulsion recycled from engines used in previous missions, in order to reduce costs rocket launch . Kyodo news agency citing unnamed sources said that a panel of experts from the Ministry of Education, Culture, Sports, Science and Technology of Japan (MEXT) is expected to put the goal of building the missile. be equipped with recycled propulsion in an interim report drafted on May 12. The current, rocket launch costs Japan’s H2A is very expensive because the rocket propulsion will be disposed of after the missile is launched. Even the H3 – the country’s next-generation missile and expected to be launched by the end of March 2022 – is disposable. Meanwhile, the Falcon 9 missile developed by the American Space Exploration Corporation, can reuse parts that have been used in previous missions to bring astronauts, including Japanese astronaut Akihiko Hoshide, boarded the International Space Station (ISS) last month. Since the propulsion of the Falcon 9 rocket is about 10 times reusable, the cost of launching the missile is only about 6 billion yen ($ 55 million), half of the launch cost. H2A rockets Japanese. So the Japan Aerospace Research and Development Agency (JAXA) is conducting research on how to launch a small test missile to a height of about 100 meters and then land vertically in an attempt. missile reuse force. In addition, JAXA also plans to test reusable missiles on a large scale, possibly with France and Germany in 2022./.

Japanese rice balls for astronauts to the International Space Station Onigiri rice ball in Japan is one of the dishes with bold unique culinary culture of Japanese people. Even when Japanese astronauts on a mission on the ISS International Space Station, in zero gravity, they bring this dish with them but with a more special preparation. Japanese rice balls created by the Japan Aerospace Exploration Agency JAXA and Onishi Foods to prepare nutritious, easy-to-carry meals for astronauts in extraterrestrial environments. Since these astronaut rice balls are available in the Japanese market, there is an opportunity for everyone to know about food for astronauts on the ISS International Space Station in zero gravity. force. There are instructions for use on the back of the rice ball package Desiccant bag inside the rice ball package The product is called Space Onigiri, which makes special rice ball product without cooking it. The steps to do include tearing open the package, taking out the moisture-proof bag, filling the bag with water to the dotted line and shaking about 20 times, then waiting. Basically rice is hydrated, you can use cold water or boiling water. Rice ball can be eaten after 60 minutes. The resulting product is the plump rice with a bit of salmon. For the convenience of handling and enjoying the food, the user will cut the dotted line to create a triangle. Smart design from the product helps users to always be clean, have a beautiful shape as well as easy to eat. Ingredients rice ball has more salmon with enough nutrients Space Onigiri can be stored for one year, without refrigeration. Each meal costs about 378 yen, equivalent to about 80,000 VND. Currently, Japanese astronaut Hoshide Akihiko is the only person working on the ISS International Space Station. Recently, Hoshide Akihiko was selected as the commander of the space station and will assume the position for about six months. Astronaut Hoshide Akihiko is the second Japanese to command the ISS station, before that, Mr. Wakata Koichi held the position in 2014.

Again, Russia intends to withdraw from the ISS project after 2025. By then, Moscow plans to build its own orbital station for the purposes of scientific research. Previously, Deputy Prime Minister of the Russian Federation – Mr. Yuri Borisov said that the situation related to the “aging” of the ISS structure could lead to dire consequences. So Russia should create an alternative to the current project as soon as possible and not leave the astronauts at risk. In addition, Borisov added that the national orbital station in the future could become “high orbit” (located above the ISS), not only used for scientific research but also acting as a “transit base” in the mission to conquer the Moon. Russia will use the ISS international space station’s energy supply module for its future space facility As for the Science and Energy module, work on creating it started in 2012. As planned, by 2015 the device is expected to ensure energy independence for the Russian subdivision on the ISS. . However at that time only the draft design of the device was ready. NEM’s ground tests only really begin in 2018. While its launch is being delayed, Russian scientists will have to be more active in the near future as time is on. increasingly hurry. It should be noted that in addition to the NEM that will become the main module, according to Dmitry Rogozin, two permanent working modules named “Nauca” and “Prichal” could become part of the space station in the future, both modules will sent to the ISS this year.

Photojournalists installed remote cameras to be ready to record the missile launch image on April 22. SpaceX’s Crew Dragon space shuttle, set to take off atop a SpaceX Falcon 9 rocket from NASA’s Kennedy Space Center in Cape Canaveral, Florida. It will take almost 24 hours to reach the space station, whose orbit is about 250 miles (400 km) from Earth. It was originally scheduled to launch on April 22 but had to be delayed for a day due to unfavorable weather forecast. This rocket launch marks NASA’s second return to service after nine years of stopping the shuttle from space in the United States. It is also the third crew flight to be launched into orbit under a public-private partnership between NASA and SpaceX, the rocket company founded and owned by billionaire high-tech entrepreneur Elon Musk. The crew this time has 4 members including two NASA astronauts, commander Shane Kimbrough (53 years old) and pilot Megan McArthur (49 years old), along with Japanese astronaut Akihiko Hoshide (52 years old) and specialist Thomas Pesquet (43 years old), a French engineer with the European Space Agency. 6 months of space experiment Crew 2 is expected to spend about six months conducting scientific experiments and maintenance before returning to Earth in the fall. The four members of Crew 1, sent to the space station in November, are scheduled to return to Earth on April 28. Crew 2’s mission is also special in that the Falcon 9 launch vehicle using the same early stage booster has put Crew 1 in orbit. This is the first time that a proven booster device has been used again during a crew launch. Reusable booster vehicles, designed to fly back to Earth on their own and land safely after they separate from the missile’s remains a few minutes after launch. SpaceX’s reusable rocket strategy has pioneered more economical space travel. SpaceX has so far recorded more than 45 successful Falcon 9 landings, and the company has refurbished and reused the majority of them for multiple flights. However, all previous flights only carried cargo, not people, into space. The pilot of Crew 2, McArthur, will make history as the first female Pilot of the Crew and the second in her family to ride a shuttle. She is married to NASA astronaut Bob Behnken, who took a SpaceX demonstration flight last year. If all goes according to plan, they will arrive at the space station on Saturday. McArthur and her three friends and crew will be greeted by four astronauts of Crew 1 (three from NASA and one from Japan JAXA Aerospace Exploration Agency) and two crew members. Russian family and an American astronaut were on a Soyuz flight to the space station.

Billionaire Dennis Tito on the ISS. Photo: CNN CNN channel (USA) said billionaire Tito, then 60 years old, had a strong hand only 20 million dollars to realize his dream from a young age. In 1961, before the information that Soviet astronaut Yuri Gagarin was the first person to enter space, young Tito had set the goal of life. The US Aeronautics and Space Administration (NASA) does not support sending civilians into space. In 1991, not long after the dissolution of the Soviet Union, Tito started negotiations with Moscow to go to space by “spending the money”. Mr. Tito recalls: “In the late 90s of last century, the Russians really wanted more funding for the space program. So I found that I could find them ”. On April 28, 2001, the Soyuz spacecraft was launched into the air in Kazakhstan with three members on board including billionaire Tito and two Russian astronauts. Billionaire Tito then spent 8 days living on the ISS. Two decades later, billionaire Tito still remembers: “The pencils are floating and I can observe both the dark space of the universe as well as the curve of the Earth. I feel so good. It was the greatest moment in my life, reaching my life goals … I hope that others also experience the great things I have. ” Billionaire Dennis Tito returned to Earth in May 2001. Photo: CNN Since billionaire Tito’s space travel year, only a few other tourists have had the same experience. However, some American companies like SpaceX, Blue Origin and Virgin Galactic are betting on space travel with the goal of making it not too far-fetched. These people all choose the space travel program of the company Space Adventures, which uses the Russian Soyuz to bring passengers to the ISS. Since 2009, Space Adventures’ space travel program has ceased to exist because the US Space Shuttle program “retires” and only Russian Soyuz is the vehicle to bring astronauts to and from the ISS. However, a representative of Space Adventures said that once there is competition in the space travel market, there will be price competition and in the future there will be many units participating in this field. Space Adventures is still working with the Russian space agency and is working on the possibility of launching the Soyuz to the ISS by 2023 with a program to give visitors a chance to walk in space. In addition, Space Adventures is also planning a space travel in late 2021 via SpaceX’s Crew Dragon spacecraft. NASA contributed funding to the development of the Crew Dragon and Boeing’s Starliner space. However, both of these companies are privately owned and therefore have the right to sell their spaceship seats to anyone who can afford it. NASA has also changed its view of space travel since billionaire Tito’s historic trip. In 2019, NASA announced plans to open the ISS for visitors. SpaceX’s Crew Dragon. Photo: CNN Former NASA astronaut Jeffrey A. Hoffman, who currently works in the Department of Aeronautics and Astronautics at Massachusetts Institute of Technology, said billionaire Tito’s trip in 2001 marked the “beginning of a new era.” of space travel ”. Jeffrey A. Hoffman hopes that space travel costs will decrease as demand increases. The main obstacle to space travel, he said, is safety concerns. In 2014, a pilot was killed during a test flight of the Virgin Galactic company SpaceShipTwo spacecraft. In addition, there have been records of SpaceX boosters and Blue Origin – a company owned by Jeff Bezos, exploding during testing, thankfully no people were injured. According to the former astronaut, there is always a risk of an accident with air travel, but “a consistent safety record” will help this form of travel grow. May 2020 marks the first private spacecraft to bring NASA astronauts into space. That is the Crew Dragon of SpaceX. The company is expected by the end of 2021 to use the Crew Dragon for a program exclusively for ordinary people at a cost of $ 50 million per seat. SpaceX also has hopes in a spacecraft called Starship to bring Japanese billionaire Yusaku Maeza and a group of artists to the Moon in 2023. In 2019, an American company called Gateway Foundation announced plans for hotels operating in the lower layers of the Earth’s atmosphere.

The astronaut’s chair “Vostok” (East). Photo: Aleksandr Mokletsov / Sputnik. In addition, on board there is also a tape recorder used to transmit back to Earth recordings of recipes and choral songs. This particular act is intended to confuse Americans who are watching the flight and are trying in vain to decipher the encrypted information. 2. The words “СССР” on the astronaut’s hat The words “СССР” (short for “Union of the Soviet Socialist Republic”) were inscribed on astronaut Yury Gagarin’s helmet exactly 20 minutes before flying. Yury Gagarin said goodbye to his friends before flying into space. Photo: Sputnik. In the last moment, it was decided to do it so that upon landing on Earth, astronauts would not be confused with foreign spies. Because exactly a year earlier, in the airspace of the Soviet Union people had shot down an American spy plane named Francis Gary Powers. This person also wears a similar helmet. 3. Simple phrase but famous worldwide When the spaceship was launched, Yury Gagarin should have said a formal sentence saying “Crew, let’s go!”. However, he said a simple phrase that would later become famous worldwide was “Poyekhali!” (Go!). Yury Gagarin before setting off on the “Vostok-1”. Photo: Sputnik. When taking off on a regular plane, Yury Gagarin’s instructor Mark Gallay often said that, but he really did not understand what it was for when the crew had only one person. 4. The spaceship is controlled automatically Yury Gagarin’s “Vostok-1” spacecraft is controlled by automatic mode. Because, no one can predict how people in such extreme conditions will behave. Spaceship “Vostok-1” with the world’s first astronaut Yury Gagarin at departure. Photo: Sputnik. In case of a mishap, Yury Gagarin was given an envelope with a manual drive activation code. Activation codes can be obtained by solving a simple, but complex, arithmetic problem in a panic state. 5. Farewell letter Before flying, Yury Gagarin wrote a farewell letter to his wife Valentina in case he was unable to return to Earth. This letter was not received until seven years later, when Yury Gagarin died during a training flight on March 27, 1968. Valentina Gagarina and her daughter Lena read a letter to the “Little Flame” magazine after Yury Gagarin’s death. Photo: A. Golikov / Sputnik. 6. “I’m on fire, farewell, comrades!” It was not clear at the time, what a spacecraft would look like when flying through dense layers of the atmosphere. Seeing the sparks of fire on the doorway of the ship, Gagarin said that his ship was in distress and spread the news about the Earth: “I am on fire, farewell comrades!” For good reasons, people decided to forget these words. Scientists tracked Yury Gagarin’s state in space from the Flight Control Center. Photo: Sputnik. 7. Characteristics of promotion to Major Yury Gagarin flew into space with the rank of Lieutenant, and when he flew back to Earth, he took the rank of Major. There is a theory that, First Secretary of the Communist Party of the Soviet Union Nikita Khrushchev ordered Defense Minister Rodion Malinovsky to give a special promotion to Yury Gagarin, ignore the rank of Captain and go straight to Major.

Carry guns into space While the ship “Vostok-1” made a flight, for the first time in history humans brought guns into space. Yury Gagarin is given a Makarov pistol. The astronaut is expected to land in a remote area where he must protect himself from wild beasts. This happened to the crew of the train “Voskhod-2” (Dawn) in 1965, when they had to return fire to drive away swarms of wolves and bears in the snow-covered forest south of the Ural Mountains. The spacecraft device “Vostok-1” and Yury Gagarin landed on Earth. Photo: Sputnik. 9. Nearly died when he returned to Earth It was technically impossible for the astronaut to land on Earth at that time, so Yury Gagarin threw himself out and landed with a parachute. In his tight armor, he did not immediately open the valve to supply oxygen, so he was suffocated for a while. After completing the heavy duty, the first person to fly into space almost died when he returned to Earth. Yury Gagarin after returning to Earth. Photo: Sputnik. 10. “Don’t talk about this with anyone!” Two days after the historic flight, at a reception held inside the Kremlin, Soviet Communist Party First Secretary Nikita Shrushchev pulled Yury Gagarin aside and asked the astronaut if he could see God and get Gagarin. The joke is yes. The world’s first astronaut Yury Gagarin. Photo: Sputnik. The leader of the Soviet Union immediately said: “Please do not talk about this with anyone!”. After a while, BishopAlexy I came up to ask the same question. Yury Gagarin at that time joked awkwardly to the head of the Russian Orthodox Church and replied: “No, Father, unfortunately I can’t see it.” “Yury, please don’t bring this to anyone!”, The priest said.

Currently, there are 15 members participating in the ISS project, of which 5 main members are: Russia, the US, Canada, Japan and the European Space Agency. Construction of the station began in 1998, the first permanent expedition commenced operations in 2000. It was previously announced that, during a meeting with President Putin on Astronaut Day (April 12), Russia decided to withdraw from the ISS project from 2025 and start building its own Orbit Station. The first module for it will be the SEM, which was originally designed for the ISS. Roscosmos notes that the ISS modules have reached the end of their useful life. Usually IS structures are used for only 15 years, but most ISS modules, not only Russian ones, are more than two decades old. Ong Vladimir Soloviev, the leader of the flight division, spoke of the need to create the new station due to technical problems on the Russian segment on the ISS, namely detecting cracks that allow the air to escape. Although the cracks have been sealed, there are still small leaks. Russia decided to leave the ISS and build its own Space Station Mr. Soloviev predicts, after 2025 there will be mass technical problems with the parts of the station. Carrying out repairs and maintenance is extremely costly and downright dangerous. In October, Mr. Soloviev revealed the appearance of a new Russian orbital service station. Under the plan, it will include at least five modules: Basic part, target production, logistics warehouse, platform (slide) for spacecraft assembly, launch, reception and servicing, as well as one The commercial module can accommodate four travelers. According to the documents, for the purpose of being used in the Russian Orbital Station component, this module needs to be adapted to accommodate the “Angara-A5M” boosters from Vostochny aerospace, instead of missile “Proton-M” from Baikonur airport. In addition, on the module will have to replace the assembly from active to passive, place two cabin compartments for astronauts and adjust the systems in charge of movement and navigation, telemetry, communication. and heat guarantee. According to published documents, the plan to build Russia’s Orbital Station will be divided into two phases. Energy Science (NEM) modular model on the Russian Space Station In the first phase between 2025 and 2030, NEM, node, base, and entrance modules are expected to launch. In the second phase, from 2030 to 2035, Roscosmos will produce the target modules as well as the foundation for the maintenance of space apparatus. The Russian orbit station will fly in a Sun synchronous orbit – at an angle of 97 degrees from the equator, on which its solar panels will always receive light. Such orbits also allow the crew to see the North Pole every hour and a half, and every two days they see any point on our planet. In this connection, it is planned to have the part of the Earth-facing Station within the range of the observation system in various spectral bands – from optical to radar, and on the opposite side a device. are intended for monitoring outside of open spaces. To board the New Station in the first phase will be the manned transport “Progress” and the “Soyuz” manned, while in the second stage the manned train “Oriol”.

In April alone, ISS has been busy with flights up and down. On April 9, the Russian Soyuz rocket sent 1 American astronaut and 2 Russian astronauts to the ISS laboratory 420km from the Earth’s surface. Eight days later, another Soyuz rocket carried another trio of American and Russian astronauts back to Earth. On April 23, the US spacecraft SpaceX brought two more Americans, one Japanese and one French to connect to the ISS. However, such bustling scene on ISS is about to come to an end. Last week, Russia announced it would withdraw from the ISS by 2025. Despite the growing tensions between Russia and the US over the past decade, the two countries ‘space agencies continue to work closely with each other, along with 13 countries’ space agencies. According to the US Aeronautics and Space Administration (NASA), since 2000, ISS has welcomed 243 people from 19 countries. According to the Financial Times, Professor Anu Ojha, director of the UK National Aerospace Institute and an advisor to the European Space Agency (ESA), said: “I only hear positive things about astronauts and astronauts as they work together “. In the early years of building and assembling modules of ISS, since 1998, Russia and Western partners cooperated closely. “NASA and ESA cannot build a space station without Russian experts,” said Ojha. The Russians are masters of building modular space stations ”. The ISS station once welcomed astronauts from many countries Western countries need Russian rockets to carry materials and people to and from the ISS. This reliance increased when NASA decommissioned the space shuttle fleet in 2011 and Soyuz became the only passenger vehicle that could put astronauts in orbit. Only in 2020, NASA will begin to use the SpaceX spacecraft system of billionaire Elon Musk. For the Russian Space Agency (Roscosmos), cooperation with the West through the ISS also adds to the financial resources. NASA spent $ 3.9 billion to hire Soyuz to transport astronauts to the ISS from 2011 to 2019. Although astronaut Mark Vande Hei’s trip to the ISS in April may not be the last of an American on Russian rockets, the majority of non-Russian astronauts will travel on SpaceX or on Boeing’s Starliner, expected to go into service from 2022. During the first 15 years, the ISS crew focused on assembly and engineering work, which meant that the zero gravity work environment was only just being established. Recently, NASA astronaut Kate Rubins, who just returned to Earth in mid-April, recounted her hundreds of hours on the ISS to do biological experiments, from decoding DNA on a space station to growing human heart tissue and vegetables. . ISS’s most important area of ​​research is its attempt to understand the long-term effects of space travel on human health, in preparation for planned attempts at the Moon or travel to Mars. Other direction of cooperation For Russia, the decision to end ISS participation is expected to lead to more spatial cooperation with China. It is also part of the Kremlin’s broader pivot to Beijing. Since Western sanctions were first imposed on Moscow in connection with Russia’s annexation of Crimea in 2014, Russia has doubled down on its efforts to strengthen ties with China. The two countries reached agreements on defense and space cooperation while bilateral trade nearly doubled compared to 2010, reaching $ 110 billion in 2019. In 2020, Roscosmos rejected an offer from the US to join NASA-led Artemis program, aimed at bringing people to stay longer on the Moon. In March, Russia and China agreed to jointly develop a base on the Moon to “promote the peaceful discovery and use of space for all mankind” (according to a memorandum of understanding between the two. country). Roscosmos last week also said it aims to set up its own Russian space station by 2030, using modules designed like the ISS. The Interfax news agency quoted Roscosmos Director, Dmitry Rogozin, as saying: “It is likely that by 2030, we can put a space station into orbit, that will be a huge breakthrough.” On Russian television, Deputy Prime Minister Yuri Borisov said that in the future, on the Russian space station, in addition to astronauts, there will be the participation of artificial intelligence and robotics. He stressed that Russia is ready to consider for foreign crews to visit, but definitely the Russian space station must be national. Interfax quoted an unnamed source as saying that Russia planned to spend up to $ 6 billion to put this project into operation. China will also soon introduce the module to build the China Space Station (CSS). The ship carrying this module is scheduled to take off at the end of April. This is the culmination of the project that the Chinese government launched in 1992. After this module goes into space, China plans to launch at least 10 more times. Another launcher carries the remaining modules and cargo to complete the CSS assembly by the end of 2022. The 100-ton, T-shaped CSS will consist of three main modules: the 18-meter core module, called Tianhe, and two 14.4-meter lab modules, called Wentian, that are permanently attached to the sides. of the core module. As the station’s control and control center, Tianhe can accommodate 3 astronauts with a stay of up to 6 months. CSS has volume less than 1/4 the volume of ISS. Instead, configure 3 modules based on China’s need in doing the necessary scientific experiments. The 440-ton ISS with a construction cost of $ 150 billion will end its lifespan and should be returned to Earth expected by 2025. The future of the ISS is still under negotiation after the current cooperation agreements expire. by the end of 2024. According to NASA, from a technical point of view, the ISS can operate until the end of 2028. Of course, the ISS will be upgraded if it wants to last longer, especially electrical and communication systems. .

“We cannot risk the lives (of the astronauts) … The structures and metals on the ISS (are) getting old, possibly leading to irreversible consequences,” Borisov said. Disaster is waiting to happen. Borisov announced that Russia would withdraw from the ISS by 2025. However, he later delayed the time because the country needed to check the technique, decide and inform partners of the plan to build a new space station. A module of a new space station is under development in Russia. Photo: Roscosmos. The Russian Space Agency (Roscosmos) also confirmed that it is developing a successor space station for Salyut and Mir, two space stations launched into low-Earth orbit by Russia in the 1970s and 1980s. know that agreements with international partners related to ISS will expire in 2024. Share on television, Borisov said that the new Russian space station will orbit the Earth at high latitudes, helping to see the polar regions better. He leaves open the possibility of inviting foreign countries to participate in the construction of the space station. In the video posted to the Internet, Dmitry Rogozin, the director of Roscosmos, said that the first module of the space station is under development, possibly in 2025. Interfax Modules assembled by Energia cost about US $ 5 billion. Still, the prospect of a complete Russian space station is far from over. Andrey Ionin, a member of the Russian Space Academy, said that the new space station would be “a step backwards”. “ISS’s greatest achievement is not technology, but international cooperation,” said Ionin. Before building the new space station, Roscosmos still has to bring the Nauka scientific module to the ISS at the end of the year. Rogozin said Russia will not withdraw from the ISS until the completion of the new space station. However, the announcement from Deputy Prime Minister Borisov will put great pressure on the US Aerospace Agency (NASA) and its partners. Russia believes the ISS is degrading. Photo: Roscosmos. Space stations over 20 years old have regularly recorded incidents in recent times. In March, Russian astronauts patched a gas leak on the ISS that has existed since 2020. This is not the first time Russia has complained about the ISS. Speaking at the Russian Academy of Sciences in October 2020, Vladimir Solovyov, who is in charge of Russian flights at the ISS, thinks the space station will deteriorate rapidly in the next five years, advising the country to prioritize building. new universe. “The ISS partners will have difficulty maintaining the space station without Russia,” said Vitaly Egorov, the space industry watcher. Science . The magazine says SpaceX’s astronaut transportation services can fill the void left by Russia. Two astronauts installed the support frame outside the ISS station Two NASA astronauts step outside of the International Space Station (ISS) to install supports for new solar panels.

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.

On this commemorative milestone, Mr. Boris Volynov, Soviet cosmonaut, twice Hero of the Soviet Union, the last living astronaut from the first astronaut team, who made two flights into space. , shared with Sputnik about the selection of astronauts at the time, about his relationship with Gagarin and about the cause of the death of astronaut No. 1. – How was he selected in the space pilot team? – Boris Volynov: In 1955 I graduated from the training school and became a pilot of the Moscow air defense force, serving in Yaroslavl. The work is very complicated and difficult. There is practically no day off. One day, I received an order to the command of the regiment. Before entering the office, I was invited to another room, where the KGB National Security Agency representative asked me to sign a nondisclosure agreement. Entering the office, there were no regimental commanders, but strangers instead. T I was asked to do the life-risky job of flying at higher speeds and higher altitudes than our fighters, although we are still proud of the fact that we fly at high speeds and contemporary highest altitude. I agreed to accept a new assignment, then after a short time I received an order to make a business trip to Moscow. We go through a selection of pressure chambers, on centrifuges, on special swings to test the vestibular apparatus. The total challenge time is 40 days and nights. Out of the five regimental pilots who were called to the Army Hospital, only I was the one who passed the test with a “Match” result. After a while, he received orders to return to Moscow. There are 12 people, the next day to add a 13th person. In the aviation profession, this is a number that people are very afraid of. Not a single aircraft in our air force unit has the tail number 13, no apartments in the military town are numbered 13. Such details remain bold in memory. Soviet Hero Yuri Gagarin. – Do you remember your acquaintance with Gagarin? – Boris Volynov: We get to know him better through skydiving. He thought I was good at dancing and came to consult. We arrange parachutes together. Yura had made no mistake. Right after the 17th dance, at the request of the team leader, I was assigned to be a guide and help you. We communicate not just about work. We also play volleyball together. – It was not immediately clear then that Yuri Gagarin would become the first astronaut. When do you know who will fly April 12? – Boris Volynov: Until the very last moment, we still don’t know who will fly, Yuri Gagarin or the German Titov. For example, in space travel, human weight is very important. Being overweight always wastes the fuel of the boosters. German is lighter than Yura. It is only at the meeting of the State Committee for the Universe that it is decided who flies first. We weren’t there, but only knew of this choice during flight, when we heard Gagarin’s “Kedr” (Snow Pine) signal during radio communications with Earth. On the other hand, it wasn’t long before German flew into space as well. If Gagarin did a spin around the Earth and couldn’t feel all the “pleasure” of weightlessness, then German would be the first person in the world to experience everything on his own in a day long flight. Your night. At that time, no one knew and no one could explain how weightlessness would affect the vestibular apparatus, where the head was filled with blood. Astronaut Gagarin in the compartment “Vostok-1”. – How and where did he welcome on April 12, 1961? – Boris Volynov: That day I was in Khabarovsk at the radio broadcasting station. It is my duty to make sure to get in touch with Yura. As he passed us, he began to report: “I am entering the shadow of the Earth”. We all wonder, “How is that?”. At that time no one knew about this. So what’s more, in 1961. Why is the darkness of the Earth? We did not understand until later. Yura landed, our job done, it was time to return to Moscow. In the city, we saw a jubilant scene. It was a weekday working day, but a lot of people were gleefully pouring out into the street so I can only compare this event with the Victory Day celebration. – Why do you think Gagarin himself was chosen? Due to his inherent human qualities? – Boris Volynov : Yura is always willing to help others. Even in difficult times, he knows how to unravel the situation. He went through many hardships, but I have never seen him offend anyone. Yura is always ready to support and share. He has the qualifications, skills, intelligence to find a common voice with everyone. Once we went with him to a repair workshop. He understood everything, spoke the same language as the craftsmen. And after the flight, he talked to the members of the Academy of Sciences. Yura is “me” everywhere and at all times. – Were you involved in the investigation of Gagarin’s death? – Boris Volynov: Have. – Alexei Leonov has his own hypothesis about what happened to the jet that passed by Gagarin’s plane. And what do you think about this? – Boris Volynov: His assumptions are unreasonable. Once central television invited me, Alexei Leonov, Viktor Gorbatko, the test pilot Stepan Mikoyan, who said that the whole assumption was bullshit. And Leonov said that he did not give the full name of the faulty test pilot, who was 90 years old at the time, to avoid ruining his life. And Mikoyan knew all about the test pilots. There was only one 90-year-old man who could not pass near Gagarin in supersonic mode, because he specialized in testing transport planes. Mikoyan even did the test: he took the MiG-15UTI, and then asked to arrange two test pilots, flying at the same altitude and at the same speed as the modern supersonic plane flies by side. next to them in different directions, below, above, at different angles. The MiG-15UTI swung up and down, but no emergency situation occurred. That is the perspective of a professional test pilot. Soviet space pilot Yuri Gagarin and aerospace pilot Alexei Leonov after flight aboard the MIG-15 fighter plane – In your opinion, is this a tragic accidental scene? – Boris Volynov: Hard to say. I do not understand anything. There are many theories, of which what is the truth cannot be known. One of the assumptions was that a soldier launched a meteorological balloon. This is a device weighing about 1 kg. If the plane collided with it in the light of its headlights at high speed, it wouldn’t be a small deal. At the same time, it was impossible to see the ball early while flying at high speed. – His active period coincided with a period of competition between the Soviet Union and the United States. Now people talk more about cooperation. In your view, should competition or cooperation be better? – Boris Volynov: Competition is not bad either. In 1969 we and the Americans attended the international convention in Delhi. Due to his outstanding achievements in space exploration, astronaut Neil Armstrong received the highest award from the International Space Federation for the world’s first landing on the lunar surface, while also commanding spacecraft Boris Volynov and astronaut researcher Evgeny Khrunov receive the award for the first time in the world to pair two spacecraft and go from ship to ship in open space. At this international conference, Neil Armstrong and I shook hands. I talked to him, he is a normal person and has learned a lot in my life. When he was a little boy, he wanted to fly in airplanes. They also have the same Flight Clubs we have in the Soviet Union, except the Americans have to pay and we are free. To earn money to pay for school, Neil Armstrong did the cleaning. As a result, we both flew into outer space. 108 minutes to change the world In the early 60s, Yuri Gagarin was fortunate to be among the first 20 astronauts in Soviet history, selected by the government from 3,000 of the best military students, thereby training them for missions without Any country in the world thinks: Fly into space! Regardless of the government’s expectations, Yuri Gagarin has made history after completing a 108-minute mission around the Earth on the Orient 1 spacecraft (Vostok 1). This event helped the Soviet Union become the first country in human history to get people out of the Earth’s gravity, spread their wings out into large space. At that time, Gagarin was only 27 years old. His trophies brought the Soviet Union to become the number 1 power in space conquest. On March 27, 1968, Yuri Gagarin returned to the flight route with the task of training a test pilot on the first generation MiG-15 jet fighter. Minutes after taking off from Chkalovsky airbase near Moscow, Gagarin suddenly notified ground control that they would return to the base. However, shortly thereafter, all communications with Gagarin’s plane were lost. After the plane disappeared from radar screens, authorities sent a search team consisting of hard-wing aircraft and helicopters. Four hours later, the body of the crashed plane was found near the city of Kirzhach, 133km from Moscow. Seven years after his historic mission, Yuri Gagarin farewell to the world in tears, when he was still too young at the age of 34.

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.

Photo: Getty The Russian Deputy Prime Minister’s office also said that “information on operational incidents is being recorded more frequently than in recent times” and that an examination of the ISS is required to avoid possible emergency situations out. Astronauts have had to find a way to fix the leak due to cracks in some modules. Mr. Vladimir Solovyev, Deputy Director of Energia in charge of ISS of Russia in November 2020, said that some components of the ISS station were damaged, could not be replaced and would stop working after 2025. Energia is currently researching. to build a space station named Russia Orbital to replace ISS. The ISS was commissioned in 1998. The life cycle of this space station has been extended to 2020 and then to 2024. Dmitry Rogozin, the head of Russia’s Roscosmos space agency, said after the ISS was shut down, the Progress cargo spacecraft would pull it out of orbit. Then, the ISS will fall into the ocean like the Russian Mir space station when decommissioned in 2001./.

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.

However, research by the US Aerospace Agency (NASA) shows that humans can travel on the Moon at a faster speed than the astronauts on the Apollo. Theoretically, the time it takes to walk around the Moon is shorter than previously estimated. During the Apollo mission, astronauts “jump” on the Moon at a speed of about 2.2 km / h. According to NASA, this speed is quite slow due to the bulky astronaut suit, containing the pressure. If wearing a more comfortable outfit, the movement will be easy and maximum speed can be reached. Humans can walk on the Moon at a faster speed than astronauts during the Apollo mission. Photo: Shutterstock. Maximum walking speed on the Moon A 2014 NASA study, posted above Journal of Experimental Biology ( Journal of Experimental Biology ) tested human walking and running speeds in a simulated environment for the Moon’s gravity. According to the Live Science The team invited 8 people (including 3 astronauts) to use the treadmill on the DC-9 jet. The aircraft is piloted in a special parabolic trajectory, simulating gravity on the Moon for up to 20 seconds. Test results show that participants can walk at up to 5 km / h before running. Not only double the speed of the Apollo astronaut, the figure is almost equal to the average maximum walking speed of humans on Earth (7.2 km / h). The above speed is achieved because participants can walk while swinging their arms. This movement creates a downward force, compensating for the lack of gravity. One of the reasons astronauts on the Moon move slowly is not being able to swing their arms due to the tight suit. The footprints of astronaut Neil Armstrong on the Moon. Photo: NASA. If you apply the top speed above (5 km / h), it will take approximately 91 days to walk around the 10,921 km circumference of the Moon. Meanwhile, it takes 334 days to go continuously all the circumference of the Earth (40,075 km). Of course, that can’t happen because the Earth has an ocean. The same applies on the Moon as well. 91 days is just a number under ideal conditions. In fact, it will take longer to walk around the moon. Determine the roadmap and influencing factors Aidan Cowley, scientific advisor to the European Space Agency, says walking around the Moon is a possible task, but “too weird to be helped.” According to him, one of the biggest challenges is supplies such as water, food and oxygen. “I don’t think you would put them in your backpack because the masses are so great, even in environments with a gravity of 1/6 (compared to the Earth),” said Cowley, we need a support vehicle, also. is a shelter. “Many agencies are looking at the idea of ​​a pressurized rover, which will assist astronauts on exploration missions. They look like mobile bases, to store supplies and sleep at night, ”says Cowley. Adventurers also need suits that are optimal for mobility. Astronaut clothing is not currently designed for vigorous activity, but some agencies are developing suits that fit better, allowing wearers to freely swing their arms while walking on the Moon. Scientist, astronaut Harrison H. Schmitt was traveling on the Moon, during the Apollo 17 mission in 1972. Photo: NASA. The rugged terrain on the Moon makes it difficult to find the right route, especially the craters many kilometers deep. Light and temperature are also two factors to note. “At the equator (of the Moon), during the day the temperature goes up about 100 degrees Celsius. By night, it drops to -180 degrees C,” Cowley said. The lunar cycle leaves some days with very little, or no sunlight. Therefore, at least half of the journey will take place in the dark. The temperature problem can be solved with rovers and clothing, but it also alters the regolith state – the fine gray soil that covers the lunar background – affects movement speed. Solar radiation is an important issue. Unlike the Earth, the Moon does not have a magnetic field that deflects radiation. “If the Sun emits a solar flare or releases aurora material (CME), your state will be very bad if your body is affected by the Sun’s high radiation,” said Cowley. The circumference of the Moon is 10,921 km. Photo: NASA. The final element of the quest is fitness. Participants need long-term exercise in conditions of low gravity, so that the heart and muscles adapt. Even when everything is ideal, one person can only walk at full speed for 3-4 hours / day. If you maintain a speed of 5 km / h for 4 hours / day, it will take you 547 days (nearly 1.5 years) to walk around the circumference of the Moon, in the condition of the road without a crater, no Affected by changes in temperature or solar radiation. Cowley thinks humans won’t have the technology or equipment for this task, at least until the 2030s or 2040s. “No agency will support such missions. But if some crazy billionaire wants to try, they’ll shake hands, ”Cowley said. Astronaut Alan Shepard plays golf on the Moon Live broadcast from the lunar surface on February 6, 1971, astronaut Alan Shepard said the golf ball was flying kilometers away.

Twelve astronauts have already set foot on the Moon. The answer depends on a multitude of factors, including how fast you go, how long will you walk each day, and which detours you need to take to avoid dangerous terrain. Such a trip around the moon might take more than a year, but in reality, there are many challenges to overcome. According to NASA, a total of 12 people have ever set foot on the lunar surface, all of which were part of the Apollo missions from 1969 to 1972. Screened Earth footage shows walking around in the low-gravity region of the Moon, equal to 1/6 of the Earth’s gravity. However, research from NASA shows that humans can travel on the moon much faster than the astronauts aboard the Apollo. Theoretically, walking the circumference of the moon could be done faster than previously predicted. During Apollo missions, astronauts circled the surface at a normal speed of 1.4 miles per hour (2.2 km / h). This slow pace is mainly due to their bulky, pressurized space suit not designed for mobility. If moon hikers wore nicer sportswear, they might find it a lot easier to move. In 2014, a NASA study published in the Journal of Experimental Biology tested the speed at which people can walk and run in simulated lunar gravity. To do this, the team invited eight participants (3 of which are astronauts) to use the treadmill on the DC-9, which travels in a special parabolic trajectory on Earth to model it. simulates gravity on the moon for up to 20 seconds. This experiment showed that participants were able to walk up to 3.1 miles / hour (5 km / h) before starting to run. According to the researchers, this figure is not only more than twice the walking speed that the Apollo astronauts have, but also quite close to the average maximum walking speed of 4.5 mph (7.2 km / h) on Earth. The participants slowed this down because they could swing their arms freely, similar to the way humans run on Earth. The pendulum’s movement creates a downward force, which partially compensates for the lack of gravity. One of the reasons the Apollo astronauts move so slowly on the surface of the Moon is because they cannot do this correctly due to their tight suits. At this new hypothetical top speed, it would take about 91 days to walk 6,786 miles (10,921 km) of the moon. Meanwhile, it would take approximately 334 days to walk non-stop (i.e., don’t stop to sleep or eat) around Earth’s 24,901 miles (40,075 km) circumference at this rate, though it is impossible to do so. . Obviously, 91 days of continuous walking is not possible, so the actual hike around the moon will take longer. Walking around the moon poses a number of different challenges. “I think logically, that can be done,” said Aidan Cowley, a scientific advisor at the European Space Agency. But it will be a very strange task to assist. ” One of the biggest challenges is carrying supplies, such as water, food, and oxygen. “I don’t think you’ll bring them in a backpack,” said Cowley. “Because that would be too much mass even if you were at 1/6 gravity. Therefore, you would need to have a support vehicle with you. This vehicle could also act as a shelter. hidden. ” “A lot of agencies are looking at the concept of having a pressurized aircraft, which can assist astronauts when they are on expeditionary missions, like portable mini bases,” Cowley said. You can use it to go at night and resupply, then go back during the day and go around. ” Moon explorers will also need a space suit with a design that allows for optimal mobility. The current space suits have yet to be created for the purpose of over-maneuvering, Cowley said, but some agencies are developing suits that fit properly to walk on the moon. “The moon’s harsh topography will also make finding a suitable path around it quite complicated, especially with a meteor crater that can be several miles deep,” Cowley added. You really want to go around craters. This is too dangerous. ” In addition, you will also have to take into account the lighting and temperatures when planning your route. Because, at the equator of the moon and during the day, the temperature is about 100 degrees Celsius. And then at night the temperature drops to minus 180 degrees Celsius.

A few weeks before astronaut Yury Gagarin made his legendary flight on April 12, 1961, a mannequin in the pilot’s outfit named “Ivan Ivanovich” with a dog ” Star”.

In addition, on board there is also a tape recorder used to transmit back to Earth recordings of recipes and choral songs. This particular act is intended to confuse Americans who are watching the flight and are trying in vain to decipher the encrypted information.

2. The words “СССР” on the astronaut’s hat

The words “СССР” (short for “Union of the Soviet Socialist Republic”) were inscribed on astronaut Yury Gagarin’s helmet exactly 20 minutes before flying.

In the last moment, it was decided to do it so that upon landing on Earth, astronauts would not be confused with foreign spies. Because exactly a year earlier, in the airspace of the Soviet Union people had shot down an American spy plane named Francis Gary Powers. This person also wears a similar helmet.

3. Simple phrase but famous worldwide

When the spacecraft was launched, Yury Gagarin should have said a formal sentence that says “Crew, let’s go!”. However, he said a simple phrase that would later become famous worldwide was “Poyekhali!” (Go!).

When taking off on a regular plane, Yury Gagarin’s guide Mark Gallay often said that, but he really did not understand what it was for when the crew had only one person.

4. The spaceship is controlled automatically

Yury Gagarin’s “Vostok-1” spacecraft is controlled by automatic mode. Because, no one can predict how people in such extreme conditions will behave.

In case of a mishap, Yury Gagarin was given an envelope with a manual drive activation code. Activation codes can be obtained by solving a simple, but complex, arithmetic problem in a panic state.

5. Farewell letter

Before flying, Yury Gagarin wrote a farewell letter to his wife Valentina in case he was unable to return to Earth. This letter was not received until seven years later, when Yury Gagarin died during a training flight on March 27, 1968.

6. “I’m on fire, farewell comrades!”

It was not clear at the time, what a spacecraft would look like when flying through the dense layers of the atmosphere. Seeing the sparks of fire on the doorway of the ship, Gagarin said that his ship was in distress and spread the news about the Earth: “I am on fire, farewell comrades!” For good reasons, people decided to forget these words.

7. Characteristics of promotion to Major

Yury Gagarin flew into space with the rank of Lieutenant, and when he flew back to Earth, he took the rank of Major. There is a theory that, First Secretary of the Communist Party of the Soviet Union Nikita Khrushchev ordered Defense Minister Rodion Malinovsky to give a special promotion to Yury Gagarin, ignore the rank of Captain and go straight to Major.

8. Carry guns into space

While the ship “Vostok-1” made a flight, for the first time in history humans brought guns into space. Yury Gagarin is given a Makarov pistol. The astronaut is expected to land in a remote area where he must protect himself from wild beasts. This happened to the crew of the train “Voskhod-2” (Dawn) in 1965, when they had to return fire to drive away swarms of wolves and bears in the snow-covered forest south of the Ural Mountains.

9. Nearly died when he returned to Earth

It was technically impossible for the astronaut to land on Earth at that time, so Yury Gagarin threw himself out and landed with a parachute. In his tight armor, he did not immediately open the valve to supply oxygen, so he was suffocated for a while. After completing the heavy duty, the first person to fly into space almost died when he returned to Earth.

10. “Don’t talk about this with anyone!”

Two days after the historic flight, at a reception held inside the Kremlin, Soviet Communist Party First Secretary Nikita Shrushchev pulled Yury Gagarin aside and asked the astronaut if he could see God and get Gagarin. The joke is yes.

The leader of the Soviet Union immediately said: “Please do not talk about this with anyone!”. After a while, Bishop Alexy I came up to ask the same question. Yury Gagarin at that time joked awkwardly with the head of the Russian Orthodox Church and replied: “No, Father, unfortunately I can’t see it.” “Yury, please don’t bring this to anyone!”, The priest said.

Not to be outdone, in 1958, the US also successfully put the Explorer 1 satellite into orbit. After this period, the two sides entered a fierce race to conquer space, aiming to become the first country able to bring people to space.

Finally, the Soviet Union was the country to finish earlier, with astronaut Yuri Gagarin’s orbit exactly 60 years ago, on April 12, 1961 – the flight is historic and is considered to have changed change the world.

According to RBTH, Yuri Gagarin was born on March 9, 1934 in an ordinary carpenter family in Smolensk. At the age of 16, he moved to Moscow and then entered an engineering school in Saratov. Gagarin has been dreaming of the sky since childhood. One of the first pictures of Gagarin that his family still has is a young man standing by the wing of an airplane, raising his hand in excitement.

While still a student in Saratov, Gagarin volunteered to join an aviation club. Thanks to his talent and relentless efforts, in 1955, at the age of 21, Gagarin was sent to the Chkalov First Air Force Pilot School in Orenburg and graduated with excellent results after 2 years.

In November 1957, he officially became a military pilot with the rank of lieutenant in the Soviet Air Force. At the same time, the Soviet Union launched an artificial satellite to bring the dog Laica into space. In the early 1960s, he enrolled in the secret program of selecting astronauts for a flight to space and became one of the group of 20 brightest candidates.

After nearly a year of hard training, Gagarin has proven the qualities that show he is the best person, passing all rigorous physical and mental tests – the most important factor for an astronaut. The universe.

On April 8, 1961, major pilot Gagarin was officially selected to be the first person to fly into space. His substitute was none other than astronaut Gherman Titov, who later flew into space aboard the Vostok 2 spacecraft on August 6, 1961.

The night before the flight, April 11, 1961, Gagarin and Titov spent the night in a small bungalow in Baikonur. “I’m leaving tomorrow and I can’t even believe it will be me,” Gagarin told his colleague. At 5:00 a.m. on April 12, 1961, two astronauts were awakened and taken to Baikonur airport.

After completing the final procedures, Gagarin boarded the Vostok 1 train, Titov remained for the next mission. At 9:07, the ship and Gagarin left the launch pad. After 10 minutes, the train enters orbit at a speed of 29,000 km / h, reaching a maximum altitude of 327 km. Gagarin became the first person to see the species’ common home from outer space.

“I see the Earth, it’s beautiful,” he said from space in his colleague’s rupture on the ground.

After completing a 108-minute round-the-Earth journey, Gagarin and his landing gear landed safely by parachuting into a field in the state of Saratov. Due to his landing a few kilometers from the proposed site, the first two people to see him were an old farmer woman and a baby girl. Gagarin once spent several minutes explaining to them he was … not a Western spy, according to WION.

When a colleague appeared, he was greeted with glee. He rested for a few days and was brought back to Moscow on April 14, 1961 on a jet. Hundreds of thousands of Soviet citizens filled the streets of Moscow at that time to celebrate the country’s hero.

According to Russian media, because of the dangerous and secret nature of the flight mission, after being selected as the first astronaut, Yuri Gagarin even wrote a suicide note. If the worst happens, the letter will be sent to your family.

Also, since no one had ever been to space before Gagarin, Soviet scientists could not predict every situation that happened to astronauts. Therefore, the Vostok is controlled from the ground and Yuri Gagarin can only intervene in case of emergency.

Talking about the moment in space, Gagari said seeing the soft blue Earth, next to the dark sky, but with many bright stars. Gagarin could not see the Moon but the Sun was very bright, many times brighter than from Earth.

After the legendary flight, Gagarin participated in Soviet space training and research activities. He also spends a lot of time traveling around the world to inspire his travels and met many famous people.

In 1967, after witnessing his best friend, astronaut Vladimir Komarov, died when a mission to connect two spacecraft in orbit failed, he collapsed.

On March 27, 1968, more than a year after the death of his best friend, Yuri Gagarin returned to the flight route with the task of training a test pilot on the first generation MiG-15 jet fighter. However, the MiG-15 crashed shortly after takeoff, killing him.

At that time, the Soviet Union decided not to publish specific information about the cause of Gagarin’s death, creating many speculations. In 2011, 50 years after Gagarin’s space flight, the Russian government published more than 700 pages of documents about Gagarin, which revealed that the weather on March 27, 1968 was very complicated and the dive moves. Gagarin, or its co-pilot, put the plane in danger.

On April 12, 1961, the Vostok spacecraft carrying astronaut Gagarin was launched from Baikonour Space Airport in Kazakhstan, then part of the Soviet Union. The flight lasted just 108 minutes when the ship completed one orbit of the Earth and returned. Since then astronaut Gagarin also became a legend, and the day he took his flight became Russia’s Astronaut Day.

The historian Alexander Zheleznyakov called this a moment that gave humanity a firm conviction that discovering another world outside of the vast universe was entirely within reach. The event has made such a deep impression that the 27-year-old astronaut’s “Poekhali” has become a symbolic catchphrase for the Russian people throughout the years to come.

After 60 years, astronaut Yuri Gagarin, still mentioned as a hero of the nation. Every year, many Russian people still come to place flowers at his memorial sites across the country on April 12. Historian Vyacheslav Klimentov calls Gagarin’s miracle an inspiration to unite all Russians.

Not only loved by courage and ingenuity, Yuri Gagarin is also a shining example, a symbol of success rising from difficulties. Gagarin grew up in a working family, whose parents were carpenters and peasants. He initially studied steelmaking before being recruited to pilot the Soviet army and, at the age of 27, became the first person to fly into space.

While Gagarin was honored, the Vostok spacecraft was also put on display at the Space Travel Foundation in Moscow. Here, on April 13, there will also be an exhibition about Gagarin’s life and career, with many artifacts such as Gagarin’s documents, photos and personal belongings, from when he was a child or when he was still sitting. school chair.

Up to now, Gagarin’s flight has always been referred to as national pride for each Russian, a symbol of the Soviet Union’s power in the aerospace field. Four years before Gagarin’s flight, on October 4, 1957, the Soviet Union was also the first country in the world to put a satellite in orbit on Earth – the Sputnik satellite. Until now, the world still considered the first two “beep-beep” signals Sputnik sent to Earth triggered a race between the Soviet Union and the United States in the space field. .

In the years that followed, Russia always took the lead when Gagarin successfully flew his flight, or the fact that the astronaut Alexei Leonov became the first person to step into space and the fact that Russia was the first country to launch. the lunar probe was launched in 1966. However, three years later, the United States became the first country to send a man to the Moon.

Over the past 60 years, Russia has maintained its leading position in space exploration, steadily sending astronauts to the International Space Station (ISS). However, observers assess that Russia is competing with strong competitors such as the US and China in the race to develop space technology. In 2020, Russia loses its monopoly on human launchers on the ISS when US tech billionaire Elon Musk’s Space X Company develops and successfully put into use reusable missile systems, put astronauts the US Aerospace Agency (NASA) successfully landed on the ISS. Although the director of the Russian Aerospace Agency (Roscosmos) Dmitry Rogozin insists the agency is pursuing ambitious projects such as a mission to Venus, Mars or setting up a space station on the Moon, the Industry insiders still see this as a difficult time for Russia as competitors emerge increasingly strong.

However, the Russian people still believe in future success when looking at the historical fact that this country always appears at memorable times in human history. Not only has an influence in the aerospace field, Russia has made its mark on the historic arena with great inventions such as the AK-47 rifle, the hypersonic weapons or most recently, the COVID vaccine. -19 world’s first Sputnik-V.

These documents and images are selected from the archival and cultural institutions of the two countries: The National Russian Academy of Archives of Political and Social History, the National Archives Center III, the Bureau of Clerical and Archives. State of Vietnam, Vietnam News Agency, Ho Chi Minh Museum. In particular, some documents and documents provided by astronaut Pham Tuan …

In the book, there are a number of documents that have just been declassified, published for the first time, introduced to readers, providing valuable information and documents not only for researchers on scientific and technical achievements. the above meaning, in terms of the history of international relations, is for all those who are interested in the history of relations between the two countries Vietnam – the Russian Federation.

The book “Historical Astronaut” contains many classified documents

The book’s content is arranged into 3 parts.

Part 1 “Collaborative space research. The pre-flight preparation and training process in 1980 ”introduces documents and photos about the preparation process of the two countries Vietnam – Soviet Union / Russian Federation and the selection of pilots for the flight, as well as the process of exercising effort.

Part 2 “Departure and Activities” introduces some documents and photos of astronauts in the outer-Earth’s cabin.

Part 3 “Return to Earth”, contains pictures of the astronauts’ activities after the end of the flight, thereby highlighting the value and meaning of flight. It opens a new era, belief, hope, pride and determination in human life, production, study, as well as conquering nature and the universe.

Mr. Dang Thanh Tung, Director of the State Records and Archives Department emphasized: “The book is also a testament to the effective cooperation of the archival agencies and cultural agencies of the two countries to contribute to the At the same time, this is also an opportunity for the two Archives agencies of Vietnam and the Russian Federation to share and promote the value of archives currently preserved in the archive of the two countries “.

On July 23, 1980, pilot Pham Tuan with Soviet astronaut Gorbatko was launched into space from Baikonur space airport aboard Soyuz-37. During 8 days in space, hero Pham Tuan performed 142 orbits around the earth, conducted many scientific experiments, and photographed Vietnam from earth orbit.

In a time sharing with the students of Ho Chi Minh City University of Technology, hero Pham Tuan said that it only took him one year and three months to prepare, including studying engineering and physical training, for the flight. This time is shortened compared to pilots from other countries, because before that he was a pilot of a military fighter plane.

When the ship was just launched, people lost the attraction of the earth so the blood did not circulate normally, but put more head on the head. At that time, his face was swollen from the blood rushing to his head. Three days later, the face was pressed down so a layer of skin was removed. He lost sleep for several days, his mind was always in a state of tension.

Moving and working on a spaceship is very difficult. Eating and drinking is also miserable when they only have dry food prepared like toothpaste to eat and drink two liters of water a day.

Talking about the feeling of seeing the earth from outer space, hero Pham Tuan said it was a rare and unforgettable feeling.

“At that time, it was not Vietnam, the Soviet Union or any other country, but the earth was the home of the pilots. The happiest of pilots was that after working hours, there was a few minutes of rest and thinking. about the earth, family, relatives, “he said.

Russian President Vladimir Putin has signed a plan to start building manned orbital satellites to replace the International Space Station (ISS), which appears to be nearing its end of life.

In recent years, the ISS has started to degrade, astronauts are now regularly detecting cracks, according to RT. Last week, it was revealed that Russian astronauts are still working to seal the leak that was first discovered in 2019. The ongoing problems with the International Space Station have prompted Russia began creating an alternative device.

Called ROSS, the Russian orbital satellite will consist of three to seven modules and can carry up to four people. Although only approved by President Putin on April 12, on the 60th anniversary of the landmark first flight into space by Soviet cosmonaut Yuri Gagarin, the project has been underway for some time.

Last November, the first deputy design general of space contractor RSC Energia expressed confidence that Russia needs to start building a new station, saying that the ISS has collapsed.

“Until 2025, Russia has an obligation to participate in the ISS program” – Mr. Vladimir Solovyov told the Russian Academy of Sciences. “There were some parts that were severely damaged and no longer working. Many parts are irreplaceable. After 2025, we predict a series of failures on the ISS ”.

Russia has a long history of building its own satellites, with Sputnik 1 being the first satellite launched into low earth orbit in 1957. In 1986, the Soviet Union launched a manufactured space station. in the country called Mir – was the largest artificial satellite in orbit at the time.

Last May, the Russian Space Agency Roscomos revealed, ROSS could be ready for deployment after 2024.

Despite Russia’s willingness to do it alone, Roscosmos has reaffirmed its commitment to international cooperation in recent months. Earlier this month, Russia signed a plan to continue cooperation with the US in space and the two countries would use each other’s rockets to enter space.

Roscosmos also signed a moon exploration agreement with China in March, and agreed to share a moon station with Beijing.

While space is often a place for international competition, both Washington and Moscow often help each other when needed. For example, earlier this year, American astronauts donated food to their Russian partners when supplies from the earth were delayed.

The International Space Station is the only laboratory in the world that allows researchers to perform long-term experiments in microgravity. The ISS has been in the presence of humans continuously since November 2000. The ISS is 109 meters long, 75 meters wide – the equivalent of a football field – and weighs 420 tons. The ISS flies at an altitude of about 400km above earth. The ISS moves at a speed of about 8km / sec, or around the earth about 90 minutes / round. The travel from the launch site in Baikonur, Kazakhstan to ISS by Russian Soyuz can take anywhere from 6 to 48 hours, depending on the launch procedure and the station’s position in orbit.

Russian astronaut Sergei Kud-Sverchkov, who is currently working on the International Space Station (ISS), said in a video clip released by the Russian Federal Space Agency (Roscosmos) on April 12 – in celebration 60 years of human astronaut Yuri Gagarin becomes the first person to fly into space.

60 years ago, on April 12, 1961, the Vostok spacecraft carrying astronaut Gagarin was launched from Baikonour Space Airport in Kazakhstan, then part of the Soviet Union. The flight lasted just 108 minutes when the ship completed one orbit of the Earth and returned.

Since then, astronaut Gagarin has also become a legend. The historian Alexander Zheleznyakov called this a moment that gave humanity a firm conviction that discovering another world outside of the vast universe was entirely within reach.

The event has made such a deep impression that the 27-year-old astronaut’s “Poekhali” has become a symbolic catchphrase for the Russian people throughout the years to come.

After 60 years, astronaut Yuri Gagarin is still mentioned as a national hero. Every year, many Russian people still come to place flowers at his memorial sites across the country on April 12.

While Gagarin was honored, the Vostok spacecraft was also put on display at the Space Travel Foundation in Moscow. Up to now, Gagarin’s flight has always been referred to as national pride for each Russian, a symbol of the power of the Soviet Union in the field of aerospace.

Every year, Russia celebrates the first flight of astronaut Gagarin into space and April 12 becomes Russia’s Astronaut Day.

In 2011, the United Nations General Assembly declared April 12 to become the International Day of Flight to put people into space.

On this occasion, Russian President Vladimir Putin went to Engels, a city on the banks of the Volga River in the south of the country, the landing point of the spacecraft carrying the Gagarin astronaut on a historic flight.

Four years before Gagarin’s flight, on October 4, 1957, the Soviet Union was also the first country in the world to put a satellite in orbit on Earth – the Sputnik satellite. Until now, the world still considered the first two “beep-beep” signals Sputnik sent to Earth triggered a race between the Soviet Union and the United States in the space field. pillar.

Competition is fierce

Over the past 60 years, Russia has maintained a leading position in space exploration, steadily bringing astronauts to the ISS. However, observers assess that Russia is currently competing with strong competitors such as the US and China in the race to develop space technology.

In 2020, Russia loses its monopoly on human launchers on the ISS when US tech billionaire Elon Musk’s Space X Company develops and successfully put into use reusable missile systems, bring the NASA astronauts to the ISS successfully.

Although Roscosmos Director Dmitry Rogozin insists the agency is pursuing ambitious projects such as a mission to Venus, Mars or setting up a space station on the Moon, industry insiders still consider this time to be full. difficult for Russia as rivals emerge increasingly powerful.

However, the Russian people still believe in future success when looking at the historical fact that this country always appears at memorable times in human history.

While waiting for the Vostok-1 to be launched, the famous saying “Поехали!” Gagarin’s (“Let’s go!”) Shows his daring personality. This personality has also become a brief motto in the human travels later on.

Over the years, the space exploration community has made great strides, including the first crewed flight flight, the first female astronaut’s space walk, and a pairing experiment. to examine the impact of the environment in space on humans. Of the twin astronauts Scott and Mark Kelly, Mark will be on Earth and Scott will fly into space.

April 12 was officially recognized as the United Nations’ International Astronaut Day. Many space lovers take part in a global space party known as “Yuri’s Night” to mark a big occasion.

“Endless exploration is deeply entrenched in each of us, and space travel is a practical way to realize this extraordinary cosmic mission,” said Clément Fortin, Professor of Practice at the Center. Space under the Skolkovo Institute of Science and Technology (Skoltech) in Moscow, Russia, writes in an email.

According to him, the achievement of Yuri Gagarin opens up other great possibilities, though it is difficult to achieve in particular.

Yuri Gagarin and the first voyage into space

The first crewed trip was a milestone for all of humanity, but the day astronaut Yuri Gagarin first flew into space was a special resonance for Russians, who saw Gagarin as a taste. Valuable national hero. His name is given to many monuments, buildings and locations across the country.

“In Russia there are a lot of events being held on this day. We will participate in events that explain how space technology works and how the future of space exploration,” said Anton Ivanov. , Director of Skoltech’s Space Center, replied in an email.

The Vostok-1 is launching at the Baikonur Cosmodrome station, Kazakhstan.

Human space travel is an effort that has been successful in the past 60 years, but also leaves a lot of regret for many young people. Teenagers under the age of 20 have never experienced an undiscovered space, when there are no humans in orbit, as the space station (ISS) has been occupied since day 2. 11/2000.

Earlier, Russia’s Mir space station flew into Earth orbit from 1986-2001, pioneering multi-day crew trips. Russian astronauts Mir still holds the record for the 3rd longest in the history of mankind’s longest journeys.

Before the Gagarin flight 60 years ago, no one had set foot in space. The Soviet space program put many animals into space, such as the famous Laika, the first animal to fly around the Earth. Even so, Gagarin still faces a completely new challenge with great principles that will change the entire history of space travel, regardless of the mission.

“In the early 1960s, the missile technology was still incomplete, despite many tests, the missile was blown up,” Mr. Ivanov said.

According to him, before Gagarin’s ship was launched, there were several failed launches. Gagarin sat on the train as if riding a bomb. Since the astronauts knew the statistics well, they had the courage to board the Vostok-1 and carry out their mission.

Fortunately, Gagarin and his crew’s courage paid off. After hours inside the Vostok-1 on the launch pad, Gagarin was finally launched into the air at the Baikonur Cosmodrome launch station, Kazakhstan, at 6:07 Coordinated International (UTC).

Gagarin entered orbit a few minutes later, maintaining a calm and positive attitude throughout the 108-minute flight.

Lessons from the first flight

The cockpit of the Vostok-1 has a spherical shape made mainly of aluminum alloy and covered with abrasive material. Unlike today’s capsule cocktails, the ship carrying the Gagarin was not designed to reach the ground safely.

The small metal ball was equipped with only one escape option that Gagarin had to manipulate in order to be dropped from a great distance from the ground, so that he could parachute into a safe place while the Vostok-1 landed separately. .

After completing a round-trip around the Earth, the Vostok-1 is sent back into space. At that time, Gagarin successfully escaped an open door and fell into the countryside in Kazakhstan.

The ship carrying Gagarin was not designed to land safely, so he had to parachute to escape the ship while it landed somewhere else.

Even though the mission was a success, this was still a hair-raising risk on the back of the neck. In an email, Ms. Anastasia Ilina, founder of the Russian space diffusion community Space Flight and project coordinator of the Skoltech Space Center, described the Vostok-1 as “flight into space, one the flight has no guarantees “.

“During Yuri Gagarin’s flight, we had difficulty closing the spacecraft lid, and after launching, the ship moved in orbit faster than planned,” she said.

When she returned, she said, the push-and-brake system produced unsafe braking impulses, making the ship twisted and landed with difficulty.

“But even though there were technical difficulties, we all got over it,” added Ms. Ilina.

According to her, it was important that the first flight taught the crew (astronauts, guides, engineers) a lesson on how to coordinate work and manage space equipment.

In fact, Yuri Gagarin proved that one can step inside a metal sphere and change the trajectory of human discovery forever. Within a decade of his first flight, many astronauts in the Apollo program had landed on the Moon.

This is an American achievement born of the Cold War due to the successes of the Soviet Union that sparked the space race.

While possibly strong interstate geopolitical tensions over space travel still exist, mankind’s travels have evolved into a collaborative endeavor.

Astronauts from 18 different countries and new international collaborations such as the Artemis program led by NASA aim to bring people back to the Moon.

The advent of commercial crews also reshaped human spacecraft, heralding a new era of space travel that is imminent in the near future.
