Stairs location The stairs are the place to start the air, spreading from the bottom up or from the top down to the floors. Therefore, if the position of the stairs is in a good supply, the upper floors are good and vice versa. If the location of the stairs is in a good bow, the upper floors are all good and vice versa The starting point of the stairs in the house should be designed in a ventilated way, so it should be placed in auspicious signs such as: Yin Quy Nhan, Duong Quy Nhan, Thien Ma, Thien Loc, Dao Hoa to bring prosperity and avoid bad luck. The palace has Thien Shape, Dai Sat. Stairs area must be fully lit to absorb air circulation throughout the floors. Stairs should not be placed in the middle of the house because the central energy, the heart of the house will be drained, directly affecting the energy of people living or working in that space. Stairs should also not be in line with the door because it radiates rushing, unstable and unstable energy. Stair steps The staircase should not be designed too long or too short because it affects the beauty and fortune of the homeowner. It should be noted to design the number of stairs so that from the first step to the end, they must fall into the “birth” in the cycle of “birth – old age – illness – death”. Usually the number of steps of the stairs often falls on odd numbers such as 17, 19, 21, … The number of stairs falling into the “birth” sign is very good The number of stairs is calculated from the first step to the end, including the landing and the corridor. If there is a landing, it will be calculated as a normal staircase with the formula 4 * n + 1 = number of steps. Stair steps must be connected and sealed together to ensure that money and fortune will not be lost. Stair shape The best shape of the stairs is straight or softly curved. Although the spiral staircase is very beautiful and unique, it takes up little space but is not good in terms of feng shui because it creates a twist of air, which is not good for the members of the house. The best shape of the stairs is straight or softly curved The spiral staircase will adversely affect the members depending on the position it is placed in. For example, a spiral staircase placed in the Qian azimuth is not good for the father, in the Chan azimuth it is not good for the eldest son, in the Kun azimuth it is not good for the mother, in the Doi azimuth it is not good for the youngest child… Stair material Stairs that can be made of wood, metal or concrete are symbolic of the three solid elements. Wooden stairs are suitable for South, East and Southeast directions. Metal stairs are best placed in the Northeast, Southwest, West and Northwest directions. Stair colors The color of the stairs basically needs to be in harmony with the interior style, architecture and colors of other functional areas in the house. Regarding feng shui, homeowners can choose the color of the stairs according to their destiny as follows: – For the owner of the Kim par: You can choose the same colors for the destiny, which are colors with the five elements of Earth such as brown, earthy brown, dark yellow… In addition, colors with the five elements belonging to Kim are also a good option. like silver, white, gray. – For the homeowner of the Moc par: You should choose a color that has the five elements belonging to Water such as sky blue, navy blue, etc. or colors belonging to Moc such as green, marble. Stairs that can be made of wood are a symbol of solidity and solidity – For the owner of the Thuy family: The colors associated with this destiny are the colors with the five elements belonging to Metal such as white, silver, gray … or the colors belonging to the element of Water such as blue, blue. – For the owner of the Fire par: Colors with the five elements belonging to Wood or Fire are the options to choose such as green, moss green, red, orange… Do not choose colors with the five elements belonging to Water such as navy blue, blue skin. God. – For the owner of the Tho par: The mutual colors of this destiny are the colors with the five elements of Fire such as red, pink, purple … or you can choose the color of the Earth such as brown, light yellow … Choosing the color of the stairs according to par is only a reference plan, when deciding which color to choose, homeowners need to ensure balance and harmony with the overall overall, avoid using too many hot colors such as red, orange, purple … or dark colors like black.

Soviet Arctic explorer at station NP-8. Photo: Sputnik Searching for a Soviet research station The research station NP-8 was only used by Soviet Arctic explorers until the time the ice sheet began to split. At that time, the scientists could have been urgently evacuated and this abandoned research station continued to float in the ocean until it was destroyed. In the early 1960s, the CIA and the Office of Naval Research under the US Department of the Navy conducted a “hunt” for abandoned Soviet research stations. It is said that the Soviet Union installed American submarine sound detectors there. Initially, the target was station NP-9, detected by a reconnaissance aircraft in May 1961. However, the operation was delayed and the research station was located too far in the waters of the Arctic Ocean. Station NP-9. Photo: Sputnik In the spring of 1962, about 970km from the Canadian Air Force base at Resolute Bay, another abandoned and floating research station – station NP-8 – was accidentally discovered. This is an opportunity America cannot afford to miss. Plan “Skyhook” Considering the fact that an icebreaker can’t make it through the dense ice in the area, a helicopter won’t be able to reach NP-8’s location and the plane’s landing on icebergs Floating is also too dangerous. So the US decided to drop the agents there by parachute. But the question then is how to bring those people back [máy bay]. In the end, the US decided to use the evacuation system that the CIA used in hostile lands, also known as the “Skyhook” – developed in the late 1950s. The plan required a balloon. Helium-inflated small, a 150-meter lift and a low-flying aircraft. When the balloon rises to the required height, agents “tethered” to the balloon by lifting ropes will wait on the ground. The approaching aircraft will use a special scraper or “horn” to pull the rope while releasing the balloon. The lifting rope is then automatically wound into the winch, lifting the agent onto the plane. What happened on the iceberg? Major James Smith, an experienced paratrooper and fluent Russian, and his colleague Captain Leonard A. LeSchack, an expert in submarine surveillance systems, had three days to review everything at the research station. . A few boxes of essential equipment were dropped onto the iceberg with the agents. American B-17 bomber. Photo: Uli Elch (CC BY-SA 4.0) As the US predicted, the Soviet scientists left NP-8 station in a hurry without having time to bring all the equipment. Agents discovered more than 80 documents, collected debris from equipment left behind by the Soviet Union, took about 100 photos. By the time the plane returned to pick them up, the weather in the research station area had turned severely bad. Visibility is reduced and wind is very strong. “I was immediately in a situation that one would imagine was flying into space,” recalls Connie W. Seigrist, the pilot of the plane that arrived to pick up the agents. The “trophies” collected by the agents were easily loaded onto the plane using the Skyhook without any problems, but getting the agents on board was a difficult task. The wind caused LeSchack to be dragged nearly 100 meters until the agent tried to cling to a block of ice. Even after the plane picked up the lifting rope, LeSchack still spent up to 10 minutes “hanging” in the air in cold weather before boarding. After seeing what happened to his colleague, Smith released his balloon and held on to a Soviet tractor left beside the research station for as long as possible. In the end, Smith was lifted without any particular difficulty. “Enjoy your time. This is the first time I’ve been able to relax in about a week,” Smith joked to the pilots after being loaded onto the plane. As a result of Operation Coldfeet, the Americans discovered that the Soviet Union had made significant advances in the field of polar meteorology and polar oceanography. In addition, the US also obtained evidence that the Soviet Union used sonar equipment of US submarines in the Arctic. “Overall, the Soviet Union’s remarkable achievements in drifting stations show that they have a long experience in this field and that these research stations themselves are also very important to the Soviet government.” , the commander of the operation, Colonel John Cadwalader said.

Why are airplane windows oval? In the early 1950s, the world’s first commercial jet was developed and manufactured by De Havilland. This is considered the miracle of the aviation industry. However, after a year of use, the plane fell to pieces right in the sky and within a few months, two more suffered the same fate. Engineers scrutinized the plane’s screws and discovered that the main cause was the square window. With this design, the pressure is higher at the door corners and increases significantly in flight. So the engineers decided to replace it with round or oval windows. Why do airplanes have curved wing tips? During a flight, the pressure on top of the wing is lower than the pressure under the wing. Air tends to shift from high pressure below the wing to low pressure above and around the wing tips. In the past, the wing tips were designed to be straight, causing the airflow to cause serious turbulence. Therefore, the scientists decided to bend the wing tip upwards to reduce turbulence, prolong the durability of the wing and save a lot of fuel during travel. Thanks to this feature, everyone will feel more comfortable during the flight. Why do airplane noses have different shapes? The nose of a military aircraft is pointed, the sharper the nose, the faster it flies. However, if the nose is too long, the pilot cannot see the runway correctly, which is why civil aircraft have round noses. Russian engineers solved this problem in the 1960s. The fastest passenger jet could tilt its nose. During takeoff and landing, the aircraft tilts its nose down and during flight the nose will be brought back to its original position. This strange design is intended to help pilots see the runway better. Why are airplanes painted white? Airplanes are almost always painted white. There are several reasons to explain this problem: Heat Reflection: A plane painted white will accumulate less heat. This is better for passengers and economically beneficial for airlines.
White paint is cheaper than other paints.
Prevent bird collisions: Birds can see reflections from white surfaces better, reducing the risk of collisions with aircraft.
White paint helps reveal small cracks and dents: The paint makes cracks easier to see, identifies problems early, avoids accidents, and makes damage easier to see. Why is the exit on the left? Not all but most aircraft have the main entrance on the left side. There is an explanation: The right side is for luggage (the cargo hatch is also on the right) so it is not safe for passengers.
Some say it’s an old tradition: The train ramp is always on the left.
The aircraft door is installed on the left side, which allows them to park the plane in the passenger area better and move more easily. Why are some planes oddly shaped? You must have heard of stealth aircraft. It has an odd shape to avoid detection by radar, sonar, infrared and other detection means, and to be able to carry more luggage with less fuel consumption. The shape of the plane is inspired by birds. Birds of prey use that shape to increase their range and be less visible. However, these aircraft are often too expensive to be used in civil aviation. How do airplanes look spacious? The designers use a number of tricks to make the plane look taller and more spacious than it actually is. For example, the walls have certain shapes to reflect light correctly. The illumination between the ceiling and the overhead bin makes the ceiling visually taller. Thanks to these tips, people with plane phobia will feel more comfortable. Why don’t pilots have beards? Some airlines ban pilots from growing beards. This is explained that, the beard can cause the oxygen mask to not fit tightly to the pilot’s face and work properly in an emergency situation. In particular, in that case, the pilots must always be alert to save the lives of passengers on the plane.

On the evening of June 10, Archer company from California, USA, unveiled its new electric vertical take-off and landing (eVTOL) prototype at an event held in the city. Los Angeles. The innovative vehicle is called the electric Archer Maker, and to demonstrate what it can do, event participants were invited to participate in a flight simulator. As the problem of congestion becomes more and more difficult to solve, more and more companies are launching products and ideas that are created to take people to the sky and bypass the heavy traffic roads below. That is also what the Archer flying taxi is trying to achieve. The company’s new aircraft, the Maker, is a two-passenger eVTOL vehicle designed to serve as a test machine for new technologies. It has a distributed electric propulsion system that allows 12 electric motors to draw power from 6 individual battery packs. This design makes it possible for the Maker to maintain flight even if one or two of its motors fail. One of the main focus of the company is the noise generated by the propellers. No one wants a city filled with eVTOL vehicles hovering in the air and making louder noises than the cars below. To overcome that problem, Archer specially equips Maker with 12 sets of small propellers, which can rotate more slowly than conventional helicopter propellers. The new Archer Maker 2022 will be able to soar to about 610 meters above the ground, and according to the company, it will be 100 times quieter than a helicopter. In other words, Maker only makes as much noise as a home refrigerator. In terms of speed, the Maker will be able to reach a maximum speed of 240 km / h, and will use only 30% of the battery capacity for trips of 32-64 km. This will allow the battery to quickly charge before the next flight. The plane will be ready to take off after about 10 minutes of charging and has the potential to make 40 flights per day. In addition, it is also worth noting that the Maker has a very light weight of only about 1.5 tons, 300 kg lighter than a Tesla Model 3. Archer is expected to complete the first test flights of Maker. in the fourth quarter of 2021, and plans to start production in 2022. In an effort to reduce its carbon footprint, United Airlines has announced plans to purchase $1 billion worth of eVTOLs, and if all goes as planned, they are expected to begin flights trade from Los Angeles and Miami by 2024. The California-based company also plans to build a complete network of take-off and landing points for the eVTOLs. However, they won’t really create new spots because there really isn’t much extra space in megacities. Instead, Archer will use the roofs of the parking garages.

The pandemic “tsunami” of the past months hit and nearly collapsed India’s public health system on a large scale, in the period from mid-April to early June. In this context, thanks to careful preparation and sound resource investment strategy, southern Indian states like Tamil Nadu suffered less severe damage than other regions, according to the report. Financial Times . Prepare early for the bad scenario Jacob John, a doctor at a medical school in the city of Vellore, said the number of patients treated at the hospital where he worked at one time reached “uncontrollable thresholds”. At that time, the hospital’s 900 beds were filled, causing the facility to refuse to accept more patients and nearly drain its reserve of breathing air for treatment. But when a catastrophic second wave of disease hit Tamil Nadu and other southern states, places like Vellore were able to withstand the worst Covid-19 tragedy. The ability of these states to fight the epidemic is largely due to the planned and effective investment in the public health care system in the southern states. A woman has her blood pressure checked before getting a Covid-19 vaccine in Tamil Nadu, India. Photo: PTI. Experts say that in many other parts of India, the lack of investment and reconstruction for the public health system was exposed when the Covid-19 tsunami swept through. Tamil Nadu is recording about 22,000 coronavirus cases and nearly 500 deaths every day. Under that pressure, Tamil Nadu officials still managed to push back the wave of the epidemic. “The current situation is very difficult. We do not have enough intensive care beds and are forced to refuse to accept many patients,” said Dr. John. “I’m not saying we’re perfect, but when the wave is over, I’m sure the investments in the public health system will save lives.” Before the second Covid-19 storm made landfall, healthcare systems in many other parts of the country, including the capital New Delhi and Uttar Pradesh, India’s most populous state, were nearly completely collapsed. whole. Many patients die from lack of oxygen while the crematorium is overloaded, causing some families to choose to let their bodies float in the river. New Delhi fell before the pandemic, the number of deaths increased sharply, overloading the crematoriums. Photo: Reuters. Although the southern states of India have also “tasteed” the Covid-19 tragedy, experts say that these localities are resilient to cope with the recent outbreak of the disease. “Thanks to a well-developed healthcare infrastructure, the situation in the southern states is not as shocking as in many other places,” said Ratan Jalan, founder of Medium Healthcare Consulting. India’s southern states account for about 250 million of the country’s nearly 1.4 billion population. Kerala and Tamil Nadu are leaders in healthcare, with indicators such as infant mortality rates consistently low. Except for the state of Karnataka, other parts of South India have abundant medical supplies and many medical colleges. The Sustainable Development Report released by the United Nations and government think tanks in early June also ranks the southern states as having the best public health care systems in India. Authorities in these states also issued a blockade order in May. The strategy helped reduce the number of new Covid-19 cases, temporarily controlling the spread of the pathogen. However, Bangalore, the capital of Karnataka and India’s tech hub, still has a higher number of SARS-CoV-2 infections than other major cities. According to Ravi Mehta, an emergency worker at Apollo Hospital in Bangalore, when the hospital set up a new treatment ward at the end of April, all 30 beds were empty in just 90 minutes. When the treatment area was replenished with 70 beds, it was completely empty in less than 3 hours. Although the pressure has now eased, the hospital’s intensive care unit is still full, and is now used to treat patients with serious complications. Resource disparity States like Maharashtra in western India are also highly rated for their ability to respond to the Covid-19 “tsunami”. However, no state in the west really fights the epidemic as effectively as in the south, according to Financial Times . Kerala, where India’s first Covid-19 case was detected in 2020, is a rare state in the west with many bright spots in disease response. During the first wave of the Covid-19 epidemic, Kerala health officials controlled the spread of the disease and brought the number of corona virus infections to zero in a few days in May 2020. The number of Covid-19 cases in Kerala increased to more than 40,000 cases per day in May, but quickly dropped to the threshold of 20,000 cases per day, according to the report. Financial Times . Experts say the authorities of Kerala and Tamil Nadu have tackled the crisis by building networks of healthcare workers to help sick people find treatment. They have also created strategic systems to distribute resources such as oxygen and oxygen tanks, preventing severe shortages. The high number of infections in the southern states of India and at the same time reflect widespread testing, provide a full picture of the epidemic situation. Medical staff in Kerala, India take samples to test for Covid-19. Photo: Indian Express. On the other hand, the fact that the southern states better control the epidemic also exposes the inequality between rich and poor in the world’s No. 2 epidemic center. In May, at least 20 patients at a hospital in rural Karnataka died from lack of oxygen. In Goa, the southern tourist hub, many patients died from inadequate breathing air. PV Ramesh, a doctor and former senior civil servant in Andhra Pradesh, a state in southeastern India, said the Covid-19 crisis will force the whole country to acknowledge the failure of the medical system. public economy of this country. “This outbreak is still seen as an oxygen supply crisis rather than a management crisis (by health officials), Mr. Ramesh said. “As the wave of disease subsides, people will return to normalcy,” Ramesh said. went back to business as usual and didn’t learn any lessons.” Bringing the ashes of unclaimed Covid-19 victims to the Ganges River Indian volunteers collect ashes from crematoriums to organize funerals for Covid-19 victims in Haridwar city.

Na Hang Tua Chu bamboo forest in Pung Luong Commune, about 20km from Mu Cang Chai town, has an area of ​​over 1ha and is more than 60 years old. Opened to welcome guests from July 2020, the bamboo forest attracts visitors by its pristine beauty and has become a “check-in” point for backpackers as well as tourists from all over the world arriving in Mu Cang Chai. To get to this point we have to go on very small roads with steep, winding slopes. But the deeper we go into the forest, the more we feel the freshness of the air, the green of hundreds of thousands of bamboo trees reaching up to mingle with the clouds. With the beauty of the bamboo forest seemingly only encountered in the scenes of the swordplay movies, it has brought visitors very beautiful photography angles. That is why tourists have come in large numbers to see the scenery of Pung Luong bamboo forest. Along with the bamboo forest in Pung Luong, visitors can also explore and admire another bamboo forest that is older than that of the bamboo forest in Hang Sung village, Mo De commune. This bamboo forest is equally beautiful with the straight bamboo groves, which are arranged alternately with chairs, mats, swings… made from the main material of the trunk of the bamboo tree, creating a poetic image for the people Who loves the fresh space of nature. This bamboo forest is known to tourists because of the beautiful photos posted on social networking sites. The owner of the bamboo forest is a native and a Hmong ethnic, to have a vast green bamboo forest, it is impossible not to mention the care and protection of the people here. Mu Cang Chai bamboo forest is not only as beautiful as the scene in the movie but even more beautiful thanks to the fresh air of the Northwest highlands. Although the journey to the bamboo forest is quite arduous and difficult, you may lose your way, even feel tired because of the winding slopes, but one thing is certain that the scenery here will not disappoint you. .

Romantic scene from Korean movie Popular TV series Crash Landing on You (Landing where you) owns many expensive scenes at famous landmarks in Switzerland. The poetic scenery in the clock country helps the scenes become more poetic and romantic. The familiar scenes are Lake Brienz, Sigriswil Bridge, the village of Grindelwald, Iseltwald, Lungern, Lauterbrunnen… After the success of the film, Switzerland has become a favorite destination of tourists around the world as well as electric fans. Korean photo. The attraction of tourism in Switzerland Located in Central Europe, bordering many countries such as France, Germany, Austria, Italy, Switzerland, tourists are fascinated by the snow-capped mountains under the blue sky, clear lakes or small towns that keep the beauty of the times. Medieval. Each season here has its own beauty. Spring and summer nature stands out with clear, green colors. In autumn, Switzerland makes visitors fascinated by the carpet of dreamy yellow leaves. Winter here with snow-covered villages is equally unique. The tourism potential of this country is undeniable. However, resorting and dining in Switzerland is a rather luxurious option for many traveling believers.

Especially, in the first quarter of this year, Vietnam’s mango exports earned 125.2 million USD, up 30.6% over the same period in 2020. However, these days, the price of mangoes at the market has dropped sharply. For example: An Giang low-seeded mangoes are reduced to 9,000-15,000 VND/kg depending on the type, many places sell for 15,000 VND/kg, Vip Taiwanese mangoes are only 7,000 VND/kg, Australian mangoes are advertised. As for export goods, the price has also decreased to 15,000 VND/kg,… Not only that, mangoes are also landing in the markets in extremely large quantities. So, on the “online market” instead of selling by weight as before, mangoes are now sold in sets of several pounds or sold in boxes. Mangoes are being sold on the “web market” for as cheap as vegetables Wholesalers said that currently Vietnamese mangoes are as cheap as vegetables, retail by weight, shipping is more expensive than mangoes. So, they switched to selling in sets of a few pounds or in boxes for convenience. Ordering a whole box of 15kg Taiwanese mangoes for only 95,000 VND, Ms. Doan Thi Thanh Hai from Nguyen Cong Hoan (Ba Dinh, Hanoi), said: “A box for only 95,000 VND, the price is only about 6,700 VND/ kg”. According to Ms. Hai, in the past, she often had to buy Taiwanese mangoes with flat seeds at the price of 35,000-45,000 VND/kg depending on the time. 4 days ago, she also ordered Australian mango with large fruit, red skin, ripe yellow inside, sweet and delicious, priced at only 15,000 VND/kg. “In previous years, Vietnamese mangoes were usually more expensive,. And now the opposite. At the market, Chinese mini mangoes cost up to 25,000-30,000 VND/kg, while Vietnamese mangoes are as cheap as vegetables,” she commented. Therefore, on this occasion, Ms. Hai did not buy foreign fruits anymore, but switched to buying Vietnamese mangoes to support farmers to consume products. The retail price of mangoes at the market mostly fell to less than 10,000 VND/kg (photo: BH) On the “online market”, Vietnamese mangoes are also crowded with customers because the price is so cheap. Most women choose to buy in boxes of 9-15 kg/barrel because the price is cheaper than buying in sets, 3-5 kg/set, depending on the type. Talk to PV. VietNamNet, Ms. Nguyen Thi Thu Thuy – a large online fruit seller in Cau Giay (Hanoi) admitted that on this occasion most mango prices have dropped sharply. Some are halved, some are now only 1/3 of what they used to be. Ms. Thuy said that on this occasion, she sells many kinds of mangoes such as: acacia mango, Australian mango, Taiwanese mango, flat-seeded mango, etc. However, each time she imports a different type of mango for customers to choose from. . Mangoes do not retail 1-2kg as before, but are divided into 5kg bags or sold in boxes of 9-15kg. “Because of the unprecedented low price, on this occasion, the number of customers buying mangoes has increased dramatically,” she said and revealed that it is normal for her to consume about 1-2 tons of mangoes a day. One day, she sold out more than 3 tons, because most of the customers bought by the box. Like last week, she sold out about 10 tons of mangoes of all kinds. On this occasion, the harvest season was in full swing with the Covid-19 epidemic, so the price of mangoes at the growers plummeted (photo: BH) Ms. Bui Thi Tram from Hoang Van Thai (Thanh Xuan, Hanoi), also said that in the past half month, she has consumed around 1 ton of low-seeded mangoes every day. “A lot of people will not believe it. But low-seeded mangoes are very cheap. Big and beautiful fruit is only 15,000 VND/kg I sell in sets of 5kg, customers buy less than 1 set, buy 2 sets more, so the amount of mangoes sold every day is very large,” she shared. Last April, many growers in An Giang and Long An said that mangoes were in the harvest season but faced difficulties in exporting due to the impact of the Covid-19 epidemic, so the price plummeted. Ms. An, a mango farmer in Chau Doc (An Giang), lamented that if Hoa Loc mango was purchased for 40,000 VND/kg, now it only sells for 20,000 VND/kg, Thai mangoes are still sold. 15,000 VND/kg, Taiwanese mango varieties are sold at the garden for only 3,000 VND/kg. Traders buying mangoes in Long An also said that because mangoes in the southern provinces were in the midst of a busy harvest and encountered an epidemic, the price dropped. Accordingly, acacia mangoes reduced to 4,000-5,000 VND/kg, Cat Chu mango 9,000-10,000 VND/kg, Hoa Loc sand mango 15,000-17,000 VND/kg.

According to Business Insider, a video clip recently released by Gravity Industries (UK) shows soldiers of the Royal Marines wearing a Jet Suit personal jet produced by this company. disembarking from the speedboat, ascending, and rapidly landing on the deck of the Royal Navy’s offshore patrol vessel HMS Tamar. In the video, British soldiers fly easily over the sea like the superhero character Iron Man (Iron Man) in the famous Hollywood movie of the same name. The Jet Suit personal jet suit helps the wearer move easily through the air. Photo: CNN The exercise was conducted to explore how to land on ships as an alternative to the traditional method. In a statement, the Royal Navy said the Royal Marines used the Jet Suit to practice the “visit, board, search and capture” (VBSS) operation. VBSS is considered one of the most complex and dangerous sea missions. Traditionally, soldiers would use speedboats to approach warships and use rope ladders to climb or conduct landings from helicopters with the support of snipers and drones. Both of these methods require a lot of time to prepare the means. Meanwhile, with a personal jet suit, a soldier can fly up from a speedboat, land on a ship and then release a rope ladder for teammates to climb onto the ship. The images in the video clip show the Jet Suit’s ability to support soldiers on landing missions on board ships. “The Jet Suit provides extremely rapid access to any area of ​​the target ship, making it convenient for soldiers to carry weapons and easily move or retreat,” said Gravity Industries. . This is a tactical revolution for many special forces and can be applied more widely than just landing on ships.” With an operation time of 8 minutes, the Jet Suit personal jet made by Gravity Industries is equipped with 5 mini jet engines, including 4 engines attached to the arms and one on the back. Thanks to this design, the user can easily adjust the flight direction as desired. After wearing the Jet Suit, the user can fly at speeds up to 88km/h. This technology is a big step forward in making scenes from sci-fi movies come to life. British inventor Richard Browning, founder of Gravity Industries and a former member of the British Royal Marines, has worn Jet Suits to show the world many times and has been dubbed “Real-life Iron Man real”. Commenting on the Moskovsky Komsomolets newspaper, Russian military expert Vladimir Gundarov said that, like the supporting skeleton or invisibility cloak, personal jet suits will not be widely used in military units. . “All special equipment will be provided to the special forces and can be used in an emergency,” said Vladimir Gundarov. Besides the obvious advantages, Boris Gundarov said that personal jet suits also have disadvantages such as the lack of stealth, jet engines emitting a lot of noise and emitting a lot of heat. A person flying in the air with a personal jet suit is an easy target for any weapon, the expert notes. It is not clear how effective the Jet Suit will be if used on the battlefield, but it is clear that this personal jet suit will need to be improved to overcome some disadvantages that can endanger soldiers. as well as extending the operation time to match combat operations.

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

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

Here are some suggestions for some open space design ideas for you today: Architect Bui The Long, CTA | Creative Architects, said: to create open space for villas is relatively easy, but for townhouses and apartments, open space is something that requires a lot of thought. Because in an open space, safety and privacy are things to keep in mind. For long townhouses, separating the spaces and then intermingling with green areas, the open space has the most area exposed to natural light. Here is a solution with many variations to liven up your living space. The interweaving of open spaces according to the area from the top down is often combined with skylights and vertical traffic is a staircase that contributes to expanding the space, bringing as much space as possible. Common living space, living room, dining table or playground are often arranged in the above area. The bedrooms will be surrounded to increase family connection. T-house project with open space combining stairs, atrium and living room. In addition, architect Bui The Long said that the open space along the length of the house is also a good idea. The open space with green trees will connect the used spaces into a continuous strip, ensuring that every area of ​​the house is in contact with nature and the garden. However, this idea needs the width of the house to be wide enough to design. Another idea about open spaces along the length of the house is that these spaces will be staggered. Between the openings between the function rooms will be the garden, trees. These small gardens will be scattered throughout the house, also bringing nature to all living spaces. In addition, the open space can be reduced but still need spaces such as the arrangement along the traffic corridor, the stair landing area is large enough. The bedrooms at the end of the house can design a bathroom that opens to a green garden, connecting with the bedroom without a wall, which will help expand the space, increase utility but still be private and safe.

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

According to The Verge, China is planning to land a pair of robots on the surface of Mars, making a daring attempt to become the second country to successfully land and operate a rover on Mars. Red Planet. China launched the unmanned Tianwen-1 spacecraft from the southern island of Hainan in July 2020, with the goal of sending a rover to the surface of Mars to collect data about the source groundwater and look for possible signs of ancient life there. So far, only the US has successfully implemented the technique to bring the rover to Mars and operate it. After a journey of nearly 7 months, the Tianwen 1 spacecraft successfully moved into Mars’ orbit on February 10 and then sent back to Earth many high-definition pictures of the Red planet’s surface. Image of the surface of Mars taken by the Tianwen 1 spacecraft from a distance of 330 to 350 km. Photo: AFP. “The main mission of Tianwen 1 is to conduct a global and extensive survey of all of Mars using orbiters and to bring the probes to surface locations of scientific interest to conduct detailed investigations with precision and high resolution,” the Tianwen 1 mission’s leading scientists wrote in the journal Nature Astronomy last year.

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

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

Japan has outlined a plan to conduct tests on the new missile by 2026 and is expected to have the first full launch by 2030. H-2A boosters at Tanegashima Space Center It is known that the country intends to use the same technology as the technology that SpaceX applies to the Falcon 9 rocket. That is the first landing technology of the rocket on the floating floor. Since the early 2000s, Japan has used H-2A boosters. The cost per launch is about 91 million USD, much more expensive than other similar devices in the world. The Japan Aerospace Research and Development Agency (JAXA) plans to make the first launch of the new H-III missile before the spring of 2022. However, according to calculations, the operation of the new equipment will only cost about half the cost of the H-2A boosters. At the same time, Japan will continue to reduce operating costs in order to compete in the market, emphasized Yomiuri newspaper. The newspaper also said that, in addition to first floor reuse technology, Japan is expected to apply the achievements of private manufacturers to produce the next generation of missiles with the aim of further lowering prices. device.

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.

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

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

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

Bamboo Airway aircraft Along with this event, Bamboo Airway also announced to operate flights from Quy Nhon city to Thanh Hoa city (Thanh Hoa province) and vice versa, the route from Quy Nhon to Da Lat city (Lam Dong province). and vice versa. The operating frequency of these routes is as follows: Quy Nhon – Can Tho 5 flights / week; Quy Nhon – Da Lat 4 times / week and Quy Nhon – Thanh Hoa 3 times / week. With the opening of these 3 new routes, Phu Cat Airport is exploiting 7 routes with 60 departure and arrival flights per day. Vice Chairman of Binh Dinh People’s Committee Mr. Lam Hai Giang said that the inauguration of the flight route from Quy Nhon to Can Tho, Thanh Hoa and Da Lat marked a new development step in the field of passenger transport by air. and the tourism sector of Binh Dinh province. This contributes to the successful implementation of the Twentieth Provincial Party Committee Resolution of Binh Dinh Province with the goal of welcoming 4 million passengers by air in 2021 and 8 million passengers by 2025. Currently, Quy Nhon and Binh Dinh tourism are developing rapidly, the exploitation of the above routes will connect the tourist cities; travelers with access to faster-growing tourism hubs. Quy Nhon city currently welcomes more than 5 million tourists each year. Particularly on the occasion of April 30 and May 1, most hotels in Quy Nhon have been fully booked./.

Artwork: Teslarati.com According to NASA’s announcement, the contract to bring astronauts to the Moon as early as 2024 was signed with a value of nearly $ 3 billion. The contract will use the prototype spacecraft Starship, designed for a large crew with the necessary equipment for space exploration missions. Starship ships can land vertically on the surface of the Earth as well as other planets in the universe. So far, test flights have not been successful, but the group is working to build new test vehicles. NASA expert Lisa Watdon-Morgan said: “We have selected a partner and are preparing to implement the next phase. “We have to make sure to run the tests because we won’t send people to the Moon until the trials are successful.” Unlike the Apollo lunar landings between 1969 and 1972, NASA is currently preparing for a permanent presence on the Moon, a stepping stone to an even more ambitious plan, that is. is to send astronauts to Mars. This decision by NASA makes the race to conquer the Moon and other planets in the universe between the US and other powers becomes hotter. In the latest move, China’s aerospace science community on April 24 affirmed that this country is a cosmic power, capable of exploring space, exploring deeper areas in the universe by unmanned vehicles. . Scientists in this country also did not hide their ambition to bring people to the Moon soon. Chinese Academy of Sciences scholar Ye Peijian, Ye Peijian, said: “We are planning to conduct asteroid probes. We will accomplish this mission in 10 years. We also hope that China will soon be able to send people to the Moon in the near future. In early December 2020, China announced that the Hang Nga 5 probe had landed successfully and placed a flag on the surface of the Moon. This is the third successful Chinese landing in the past 7 years. Once a weak country in the space race, China has continuously developed aerospace programs in recent years with the ambition to conquer new territories. In early March 2021, the Russian Space Agency Roscosmos said that the country and China signed a memorandum of understanding to build a lunar space station together. The space station will be designed as a complex of experimental research facilities that operate on the surface or orbit of the Moon. Russian officials also announced that they will try new boosters to continue their lunar exploration program this year. Besides the US, Russia, China, some other countries such as Japan, European Union, India, Korea, Israel, South Africa … also announced ambitious Moon exploration programs in the coming time. Besides the Moon, conquering Mars is also becoming a target of fierce competition among countries. Just in February, the American Perseverance self-propelled vehicle, China’s Tianan-1 spacecraft, Hope of the United Arab Emirates (UAE) visited Mars one after another. According to space experts, the polls have different objectives but all show the interest of space powers to the Red planet. Not only is it intended for military and civilian purposes, the future space race is also related to economic benefits estimated to be worth trillions of dollars./.

A day earlier, eight similar aircraft departed from New Delhi and landed in London just hours before the UK officially put India on the “red list”. India is facing the second wave of epidemics, such as a “tsunami” with tremendous devastation. In the past 5 consecutive days, the number of new Covid-19 infections is over 300,000 cases / day. India broke down in the midst of the Covid-19 “tsunami”. Photo: QZ. The number of sick and fatalities is so great that hospitals, morgue and cremation grounds are overloaded. Severe medical oxygen scarcity has caused many patients to share a ventilator, some of whom do not survive right in front of the hospital. According to the Fortune India The epidemic has become so serious that the super-rich – those who have never been affected by poverty or natural disasters – are no longer safe. Running abroad on expensive private flights is considered the most likely option. And if they get stuck because flights have been halted and the borders closed, many people have come to realize that in the midst of this dire Covid-19 crisis, money is not going to help them buy the same perks as before. When money can’t buy oxygen Talking about the fleeing of the super-rich in recent days, journalist and historian Hindol Sengupta relates to deeper problems in Indian society: rich and poor disparities and rich people are only worried about it. live by yourself. “The long-standing bad habit in India is just to keep your house clean, you can dump trash right in front of the door. The moment the junk was out there, it was someone else’s problem. Who cares about the poor having to deal with its consequences when the well-off can still hide in their homes? ”Mr. Sengupta said. Over the years, the rich are getting richer, but their social progress and development have declined. Instead of campaigning to improve public services that serve all, the Indian elite and the middle class have found an easier way: spending money to buy private services. The Covid-19 wave left hospitals in India exhausted and depleted of oxygen. Photo: AFP. “Regardless of what happens to the rest of the country, they are comfortable with their own perks.” No matter what a crisis is, electricity, water, roads or air pollution, rich people just need to splash money. If the pollution is severe, they buy air filters at home and in the office. The city is insecure, they can hire a 24/7 private security guard. The health system is poor, they seek private doctors or quickly go abroad for treatment … “The Indian rich do not understand that not privatizing everything, a stable society, which ensures the most basic things such as health and education for everyone, is the foundation for development. sustainable, ”said Mr. Sengupta. Time of salvation The ongoing “Tsunami” of Covid-19 is said to be a landmark. Now, even the most expensive and exclusive hospitals run out of something as basic as oxygen. The elite gradually realized they could no longer spend money to get out of this crisis and had nowhere to fly to because most countries such as Canada, UAE, Thailand, Maldives, UK are in turn. processing tourists from India. The Indian super-rich flee abroad on private planes. Photo: Shutterstock. The scholar Abhinav Prakash argues that this is a time when Indians become more deeply aware of inequality in society and towards specific solutions. “Health insurance cannot help in a health crisis without infrastructure. No matter how expensive your health insurance is, it doesn’t make any sense if the hospital runs out of bed, lacks equipment, runs out of oxygen, “Prakash said. India, and most importantly, a growing rich middle class need to realize that public services are the backbone of a united society. “You can throw trash outside, but the stench of trash still gets into your closed doors and windows. It will make you suffocate. Big change comes from times like now. If the rich and relatively wealthy in India realize that their future is tied to a better public service system, it may be the time to save the country, ”wrote journalist Sengupta.

Many countries around the world are silently deploying plans to exploit Helium-3 from the Moon. Photo: Johnson Search Group Why does America want to return to the Moon after almost half a century? Why does China’s Hang Nga ship collect land on the Moon? Why Russia shook hands with China to build a Moon research station? And why has the Moon become the indispensable spot of great powers? Some say that it is to satisfy human curiosity, there are also opinions that it is to demonstrate the power of space science and technology of a nation. All is speculation, but the most important reason can be said that the Moon itself is an invaluable natural mine. As humanity is facing an energy crisis, governments around the world are looking for alternative sources of energy. High-tech companies have been exploiting non-fossil energy sources from the wind, the sun and the waves full of rivers. But that is not enough. Many countries have begun to look for new sources of energy outside the Earth. During resource exploration on the Moon, Chinese experts have discovered that there are more than 100 types of mineral resources on the Moon, not only have dozens of essential energy sources for the Earth, but also one The perfect energy source – Helium-3. Rare gas resources on the Moon. Photo: Sohu Scientists have found radioactive substances such as helium in soil on the Moon. After further analysis and determination, they found a large amount of Helium-3. Helium-3 is a valuable fuel source, because it can generate extremely high heat through fusion fusion without emitting almost no harmful radioactive neutrons. As such, fourth generation nuclear weapons using pure Helium-3 will generate little or no radioactive dust. Why does the Moon have so much Helium-3? During internal nuclear fusion, the Sun will generate a large amount of Helium-3, and Helium-3 will fall on surrounding planets after being blown by the solar wind. Because the Earth’s surface is covered by a thick atmosphere, the solar wind cannot reach the Earth’s surface, so the natural reserve of Helium-3 on Earth is very low. The Moon has almost no atmosphere, so the solar wind can directly reach the surface of the Moon, and a large amount of Helium-3 will be deposited on the surface of the Moon. The amount of Helium-3 on Earth is very small and Chinese scientists estimate that the reserve on Earth is only about 500 kg, difficult to meet the needs of mankind. The soil on the lunar surface contains at least 1 million tons of Helium-3, 2 million times more than the Earth. Experts calculated that 100 tons of Helium-3 could meet the world’s electricity generation needs in one year, and 1 million tons would be enough for 10,000 years! If Helium-3 in lunar soil could be developed and used, the construction of a nuclear power plant on the Moon could be done on the spot. But it’s not easy to separate Helium-3 from the Moon. First, it is necessary to heat the lunar soil to more than 700 degrees C to separate Helium-3. However, there is no oxygen on the Moon and is very difficult to burn. Moreover, to extract Helium-3, it must be based on the Moon, so far no country can do it. Since Helium-3 has significant energy and reserves advantages, the future Moon is more likely to become the “Persian Gulf” energy that major powers compete in the new century. In December 2020, the Chinese ship Hang Nga 5 returned safely after a mission to explore the Moon, bringing about 2kg of rock and soil from this planet to Earth. Under former President Trump, the 2020 NASA budget allocation plan shows that Washington wants to send people to the moon again before 2028. Former US Vice President Mike Pence also declared the United States to be the first power. first put a man on the moon in the 21st century. From unmanned exploration to manned landing on the Moon, and setting up lunar bases, China and the Western nations have consumed countless manpower and materials to not only satisfy scientific achievement. Behind that is endless resource ambition.

Departing on April 29 and coming back on May 2, passengers will have to pay about 7-8.4 million VND including tax fees. Specifically, if you choose the cheapest flight, you will travel on the departure flight at 13:05 and arrive at Con Dao at 15:25, with a round-trip ticket price of 7 million VND including tax and fee. During the peak of April 30 – May 1, the fare for a direct flight from Hanoi to Con Dao reached more than VND8.4 million per round-trip ticket, higher than the peak ticket price of Tet 2020 before translating Covid- 19 outbreaks. Photo: BAV. In addition to many flight options priced at about VND 8 million round trip, this flight also recorded a pair of round-trip flights with a total ticket price of up to VND 8.4 million / passenger. The departure of this flight with the price of 8.4 million dong is the flight departing at 12:30 from Noi Bai airport and arriving at Con Dao airport at 14:55 on April 29. The return leg of the journey will depart at 9:25 am on May 2 and land at Noi Bai airport at 11:50 am. Ticket price for the first leg of the itinerary is VND 4,245,000 including tax and return fare is 4,205,000 VND, making the total ticket price up to 8,450,000 VND. These non-stop flights are operated by Bamboo Airways with the 195 regional Embraer jets. In addition to the option to fly directly with Bamboo Airways, passengers can save money by transiting in Ho Chi Minh City with other airlines. flights of Vietnam Airlines Group. The cheapest round-trip fare that Vietnam Airlines and Vasco offer on the same flight sector is 4.5 million VND including tax and fee. Passengers will move to Ho Chi Minh City and transfer to Vasco’s ATR 72 to continue their journey to Con Dao. This kind of flight is half as cheap as a direct flight. However, passengers’ journey will last from 4 hours 30 minutes to more than 6 hours due to plane transfer. Meanwhile, the direct flight option only takes 2 hours and 20 minutes. In addition, the Embraer 195 experience is also more appreciated than the ATR 72 propeller airplane experience. According to the Aviation Administration, in the first quarter alone, Con Dao airport welcomed nearly 221,000 passengers, an increase of 2 times over the same period last year. Having direct flights from Hanoi and other northern provinces has made Con Dao tourism more accessible to passengers. Rising passenger demand and low Con Dao flight supply capacity, each flight can carry only 68 passengers (ATR 72) or 100 passengers (Embraer 195), making Con Dao fares always in the highest group in the market. inland.

Korean Air and Asiana Airlines aircraft at Incheon International Airport, South Korea. Photo: Yonhap / TTXVN The “Non-Landing International Tourism” service started trial operation in December 2020 and was initially only conducted at Incheon International Airport. However, starting next May, the project is approved to expand operations at other international airports such as Gimpo, Daegu and Gimhae. This is also considered as a plan to help domestic airlines expand supply in the context of increased demand because visitors participating in this travel package can make duty-free shopping similar to foreign tourists. often. It is expected that in next May, 7 Korean domestic airlines will declare another 23 flights at Incheon International Airport, 18 flights at Gimpo International Airport, 13 flights at Gimhae International Airport and 2 flights. at Daegu International Airport. MOLIT data also shows that as of March, domestic airlines have deployed a total of 75 flights, receiving more than 8,000 passengers. The number of “International Non-Landing Travel” flights was cut in January due to a recurring outbreak of COVID-19 but has recently been reopened. The proportion of passengers attending this type in December 2020 reached 49%, then exceeded expectations at 73.5% in the following months. Revenue (from ticket sales only) is estimated to range from 20 million won (17,905 USD) to 98.2 million won (87,930 USD) / trip. According to MOLIT, when using this service, passengers do not need to go through the immigration / immigration process. The plane will fly over the airspace of another country without landing in that country and back to South Korea. Passengers traveling on the plane will be eligible for tax-free purchases like regular tourists, which means each person can buy duty-free goods under $ 600 (maximum 1 liter of wine, 200 cigarettes, 1 bottle of perfume). However, passengers will have to book a ticket in advance, when getting on and off the plane must go through a private path and only use the provided transport vehicle. Passengers are required to wear a mask during the journey and do not have to quarantine themselves after returning to Korea.

(Source: design-paprika.com) According to the Vietnam News Agency correspondent in Seoul, the Korean Ministry of Land, Infrastructure and Transport (MOLIT) on April 22, said that it began to be put into test operation from December 2020, until now the flying product ” International travel without landing “of” land of Kimchi “has shown high efficiency. Therefore, the 7 domestic Korean airlines will increase the number of flights of this type from 19 flights in April to a total of 56 flights from next May, an increase of 194%. According to MOLIT, the “Non-Landing International Tourism” flight product was initially only made at Incheon International Airport. However, starting next May, the project is approved to expand operations at other international airports such as Gimpo, Daegu and Gimhae. This is also considered as a way to help domestic airlines expand supply in the context of increased demand as visitors participating in this travel package can make duty-free shopping similar to tourists foreign common sense. It is expected that in next May, 7 Korean domestic airlines will declare another 23 flights at Incheon International Airport, 18 flights at Gimpo International Airport, 13 flights at Gimhae International Airport and 2 flights. at Daegu International Airport. MOLIT data also shows that as of March, domestic airlines have deployed a total of 75 flights, welcoming more than 8,000 passengers. The number of “International Non-Landing Travel” flights was cut in January due to a recurring outbreak of COVID-19 but has recently been reopened. The proportion of passengers attending this type in December 2020 reached 49%, then exceeded expectations at 73.5% in the following months. Revenue (from ticket sales only) is estimated to range from 20 million won (17,905 USD) to 98.2 million won (87,930 USD) / trip. According to MOLIT, when using this service, passengers do not have to go through the immigration / immigration process, will have to sit on the aircraft for a certain period of time and the aircraft will fly over the airspace of another country without landing. that country and back to Korea. Passengers traveling on the plane will be eligible for tax-free purchases like regular travelers, meaning each person can buy duty free goods under 600 USD (maximum 1 liter of wine, 200 cigarettes, 1 bottle of perfume). However, passengers will have to book a ticket in advance, when getting on or off the plane must go through a private path and only use the provided transport vehicle. Required passenger wear the mask during the journey and do not have to quarantine yourself after returning to Korea./.

Nhat chi mai, snow mai, bar willow, … are very popular types on this Lunar New Year. Customers like the most because this is an elegant hobby, but the price does not “burn hands” like every year. The most valuable species of apricot tree is classified into the group of four quarters representing the four seasons of “conifer-bamboo-chrysanthemum-mai”. This year, the people of Ha Thanh had a movement to play the most chi mai – the hobby of playing ornamental plants on Tet holiday has existed since ancient times. Through the cold winter days, apricot still grows steadfastly and blossoms radiantly when spring comes like a gentleman who always keeps himself high, thus being regarded by the ancients as a “prince tree”. Although Nhat Chi Mai has the straightforward and resilient character of a gentleman, she also has a slender and graceful look like a young woman. The price of apricot blossom this year is cheaper than last year, the price is only 200-300 thousand VND / pot. This New Year, the snow blossoms emerge as a bright star and are bought by many women. (Photo: KT) Each apricot snow branch is about 1 – 1.5m long and there are many flowers and buds on the body. (Photo: KT) Each flower is very small, but because a branch of apricot blossom has many flowers, it creates a very attractive whole. (Photo: KT) The price of apricot snow ranges from 20 to 50 thousand VND per branch. (Photo: KT) Willow bar has a strong vitality and high durability, so many people choose to buy it for Tet this year. (Photo: KT) Willow bar price is only about 150-200 VND / small bundle. (Photo: KT) Willow flowers are sold at many stores, on the streets of Hanoi on the occasion of Tet. (Photo: KT) Willow bar has many vibrant colors, easy to plug, play for a long time with little care, so many women like it./. (Photo: KT)

NASA shared a set of pictures showing what the upcoming Lunar Gateway space station (Lunar Gateway) looks like when it launches to the moon in 2024.

NASA said the orbiting laboratory will provide astronauts with a “distant home” during their lunar trips and serve as a lunar replenishment station. This orbital laboratory can accommodate 4 people, and NASA will cooperate with existing partners of the International Space Station in Europe, Japan and Canada.

Most of the space station will be built by commercial partners and will provide a docking port for the SpaceX starship lunar lander, which will transport astronauts between the orbital base and the lunar surface.

NASA also confirmed that the platform will help solve one of the biggest problems of space travel outside the Earth’s orbit by measuring radiation levels. The radiation detection research instrument kit is planned to be launched in the first module of the multi-purpose international outpost, which will orbit in an elliptical 7-day orbit around the moon.

The “Lunar Gateway Space Station” is the core part of the “Artemis” mission. By 2024, NASA will send the first woman and a man to the moon, but this may be delayed. Most of them will be launched to the moon using NASA’s new Space Launch System rocket.

The development of the rocket is almost complete, and the first test flight will be carried out later this year or early next year, which will allow the Orion spacecraft to fly around the moon without a crew.

However, NASA announced in February that they would use SpaceX’s Falcon Heavy launch vehicle to begin construction of the “Gateway” space station. SpaceX will launch the basic modules of the Moon’s Orbital Gate, including Power and Propulsion Elements (PPE) and Residence and Logistics Outpost (HALO). They are expected to be launched to the moon in May 2024 at the earliest, but may also be October 2024 at the latest.

According to the Artemis plan for manned return to the moon, NASA hopes to use the Space Launch System rocket to send four astronauts into the Orion capsule, and then dock with the “Gateway” lunar space station.

The first manned mission will be called “Artemis 3”, and up to 4 astronauts will enter the lunar orbit in the “Orion” space capsule. If ready, they will be there and “Gateway”. “Butt.

The starship will be ready, waiting to dock with the portal to welcome the two astronauts on the last part of their journey on the surface of the moon. The idea is to make the “Portal” an intermediary, but in the initial mission, “Orion” may directly dock with the starship-if the “Portal” is not ready yet.

Astronauts will stay on the moon for a week, then board the starship to return to lunar orbit, and then take Orion back to Earth. When it starts in 2024, the “gateway” can accommodate up to 4 people, but over time, it is expected that facilities will increase and new modules will be added.

This is similar to the growth of the International Space Station, which currently has 7 personnel. Since its launch in the late 1990s, it has gradually increased from 3 to 6 people.

In the future, with the launch of the new module of the Lunar Gateway Space Station, it may become a science and exploration center far away from the Earth’s near orbit.

There will be four core modules at launch, the power and propulsion element (PPE), which was originally part of the asteroid redirection mission, but was later cancelled by the NASA Jet Propulsion Laboratory team.

It will serve as the “gateway” command and communication center and provide power to a wider range of sites. It was built by Maxar Technologies, which won a $375 million contract from NASA.

The second major module, which will be launched by SpaceX in 2024, is the Residential and Logistics Outpost (HALO), built by Northrop Grumman and headquartered in the United States. “Cygnus Cargo” (Cygnus Cargo) supply module. It will be equipped with a pair of interfaces, batteries, communication antennas and a fully pressurized cabin for command, control and data processing capabilities.

The third module, built by the European Space Agency, is called the European System Fuel Support, Infrastructure and Telecommunications (ESPRIT) module, and will also be launched in 2024. It will provide additional power, communications, airlocks and scientific capabilities for the other two core modules, built by Airbus and Thales Alenia Aerospace.

Before a series of cult couples dress super simply when dating, netizens think this is a way for them to avoid attracting attention and not being recognized by the audience. Because when dating secretly, why Koreans always want to disguise as discreetly as possible, so they can’t dress too well.

The aircraft carrying the Cessna Grand Caravan 208B trademark made its first self-driving flight. However, self-driving flights can only serve distances under 500 miles and are of considerable commercial importance. Xwing believes that they can gain a foothold in the context of increasing freight demand. “Over the past year, our team has made significant progress in expanding and refining its AutoFlight,” said Marc Piette, CEO and founder of Xwing. for seamless integration of operations from runway to takeoff, landing and flight operations, all overseen from our operations center via data link routes. In addition, our tested commercial freight operations have provided essential supplies including Covid-19 vaccine to remote communities as of December 2020 ”. The recently conducted flight is a Cessna Grand Caravan 208B-branded aircraft that has left the runway, took off, landed and returned to the fully automatic starting point. The flight is monitored remotely and all air traffic control interactions are performed from the ground. After the recent crashes related to the self-driving system failure on Boeing 737MAX aircraft, many people believe that passenger confidence has been significantly eroded. However, a recent ANSYS study found that was not the case. In fact, 70% of passengers say they’re ready to fly on self-driving flights. Xwing’s entry into the self-driving airline market is seen as the right moment. Recent reports show that by 2025, there will be a global shortage of about 34,000 pilots. The logistics services (logistics) are also under tension with the increasing demand for fast delivery. With the increase in e-commerce sales amounting to $ 4.2 trillion, the success of e-commerce inherently depends on the efficiency of the air transport industry. Xwing plans to leverage its technology for e-commerce logistics, allowing more access to small airports and more efficient freight transportation. Phan Van Hoa (according to ZDnet)

Fortunately, the second half of the 2,600-ton submarine, 73 meters long, displaced the water, remained undamaged after the fire. And in the difficult emergence of wisdom, French naval officials had the idea of ​​pairing the rest with its “sister” – the Saphir submarine. Perle nuclear submarine intact. Photo: Reddit Although decommissioned in 2019, and waiting to be dismantled, the Saphir front section remains relatively stable in construction. Therefore, French authorities determined that the ship could still be combined with the back of Perle to form a new attack submarine. Perle was subsequently relocated from Toulon to Cherbourg in December of last year. The workers cut it in half and the Saphir. According to French naval contractor Naval Group, earlier this month, the second half of the Perle and the front half of the Saphir were put on “conveyor” at the shipyard in Cherbourg, so that they can be carefully calibrated and welded. together. Perle submarines after being burned by fire nearly half. Photo: Marine Nationale A Naval Group spokesperson said assembly will continue to be completed in the coming months. The complete submarine, still named Perle, will be about 1.5 meters longer than its “predecessors” thanks to an additional “intersection zone”. The intersection zone on the new version of the Perle submarine will add a bit of living space for about 70 sailors operating inside the ship. Digital model According to Naval Group, all assemblies are simulated using 3D digital methods before being applied to a real ship. This is the effort spent more than 100,000 hours of technical research and 250,000 hours of manual work by more than 300 technicians and shipbuilders. Two pieces of the Perle submarine after being cut in half at the Cherbourg Shipyard, France. Photo: AP Franck Ferrer, Director of Naval Group Services, said in January the new version is expected to return to Toulon by the end of this year, for further engineering and upgrade of the combat system. . The ship will rejoin the French Navy fleet in early 2023. “The implementation of the project for these cases, namely the repairing and joining of parts of two sister ships together, was the first thing Naval Group did in modern history,” said Ferrer. said. Rare luck The Perle was not the first instance of two parts of two different ships being assembled together. According to Thomas Shugart, a retired commander of the American attack submarine, the US Navy did the same thing by replacing the damaged bow of the USS San Francisco with the bow of the soon-to-be retired USS Honolulu. The process of assembling two-part Perle submarines with Saphir. Video: Le Télégramme However, the Perle submarine can “revive” is still considered a rare luck compared to similar cases in the past. In 2012, a disgruntled worker caused a serious fire on the USS Miami submarine, while the ship was undergoing repairs at the port of Portsmouth, Maine (USA). The ship then became a waste product due to the high cost of restoration. By 2020, the amphibious assault ship USS Bonhomme Richard is also damaged by fire while being upgraded in San Diego port (USA). After determining it would take up to $ 3.2 billion and seven years to repair, the USS Bonhomme Richard was finally removed from service with the US Navy.

In the spring of 2021, the Gigabit Optical Network (F5G) “fires.”

The two sessions this year, the “14th Five-Year Plan” and the 2035 long-term goal outline have clearly put forward the “promotion and upgrading of gigabit optical fiber networks.” The “Gigabit Optical Network” was written into the government work report for the first time, and the Ministry of Industry and Information Technology also issued a specific construction action plan. For a time, the industry’s attention to the gigabit optical network reached a new height.

Recently, Huawei’s “2021 Global Analyst Conference” was held in Shenzhen. At the sub-forum “Intelligent All-Optical Network: Accelerating Gigabit Optical Network Construction”, Guangxi Telecom General Manager Ye Songhua said, “The construction of a Gigabit optical network can only be done by waiting. Cars, cars can’t wait for the road”. In his view, Gigabit optical network is the “bearing base” of communication infrastructures such as 5G, data centers, and the Internet of Things, and needs to be deployed in advance.

In addition to the “construction landing” of the gigabit optical network, exploring “application scenarios” is also a big problem. In this regard, Jin Yuzhi, president of Huawei’s transmission and access product line, revealed that Huawei plans to implement at least 100 Gigabit optical network application projects in the next five years, focusing on five areas of education, environment, health, development, and production.

Why accelerate the construction of gigabit optical network?

When it comes to 5G, everyone is no stranger; when it comes to F5G, few people know. 5G is a mobile communication network technology that focuses on wireless and mainly serves the access of mobile terminals such as mobile phones. And F5G is a fixed communication network technology, the focus is on wired, also known as “Gigabit Optical Network”, the main business is fixed network optical fiber broadband access.

Compared with the application scenarios, 5G is suitable for mobility and multi-connection scenarios, such as drones, car networking, etc.; F5G is suitable for fixedness, large bandwidth, low latency and high security scenarios, such as industrial Internet, data center Interconnection and enterprise parks, etc.

Like the fifth-generation mobile network technology represented by 5G, F5G has undergone more than 40 years of evolution, namely the F1G, F2G, F3G, and F4G eras. The corresponding era is the voice era, network era, video era, and 4K era. . In this “history of evolution”, different application scenarios have appeared in each era, and the work and life of each era have undergone tremendous changes.

Under the “Broadband China” strategy in the past, my country implemented the first “optical reform” characterized by “optical advancement in copper retreat”. In this cycle, our FTTH (Fiber to the Home Capability) penetration rate has reached 93%. Today, the “second optical reform” kicks off, and the past 100M optical network is being upgraded to a gigabit optical network.

Why upgrade to a gigabit optical network? According to iiMedia Consulting’s data, the number of online education users in China will exceed 300 million in 2020, and the symmetrical upstream and downstream bandwidth requirements for online courses are not less than 100Mbps, which needs to match the operator’s 500Mbps broadband package; remote office in China The scale of enterprises currently exceeds 18 million, and the smooth HD conference experience requires that the network packet loss rate is at least less than 1%.

With the explosion of the cloud economy and thousands of industries shouting for digital transformation, it is imminent to upgrade the existing fixed network with a large bandwidth, low latency, high reliability, and simple deployment of all-optical networks.

In the “Dual Gigabit Network Coordinated Development Action Plan (2021-2023)” issued by the Ministry of Industry and Information Technology a few days ago, it was proposed that by the end of 2023, the Gigabit optical fiber network will have the capacity to cover 400 million households. Broadband users exceeded 30 million, and 100 gigabit cities were built.

The government work report was written for the first time, and the Ministry of Industry and Information Technology issued a specific construction action plan. The “Gigabit Optical Network” has now entered the fast lane of development. Zhang Haiyi, deputy director of the Institute of Technology and Standards of the China Academy of Information and Communications Technology, said at the forum that my country’s gigabit optical network construction is in a “climbing period” and the principle of “moderate advancement” needs to be considered, and 10G PON, OTN and other digital bases should be accelerated. Network capacity building.

In this context, Guangxi, Shandong, Shenzhen and other places have begun to increase the construction of gigabit optical networks, and some of them have put forward clear construction goals. Ye Songhua said that in the next three years, Guangxi Telecom plans to build 14 cities into “Gigabit Cities” to strengthen the coordinated development of Gigabit optical networks and 5G; Li Zhuangzhi, technical director of Shandong Unicom’s Network Department, also revealed that Shandong Unicom will be Fully open the integration of cloud and light to explore, and combine the needs and characteristics of government affairs, finance, medical, manufacturing and other industries to provide industry solutions.

Construction and landing require the efforts of all parties

In fact, it is not simple to promote the construction of gigabit optical networks in an all-round way.

Jin Yuzhi said that the “secondary reform” put forward two new requirements. First, it is necessary to realize Gigabit home access on the home side, including further upgrading from FTTH to FTTR (Fiber into the room), home Wi-Fi speed to realize Gigabit and so on. Second, on the industry application side, Gigabit optical networks should be used to collaborate with 5G to promote the digital transformation of thousands of industries.

The first is FTTR, which connects optical fibers to every room. Huang Zhiyong, vice president of Huawei’s transmission and access product line, told reporters that neither the twisted pair technology nor the power line technology can carry gigabit bandwidth. “The carrier of the power line is hundreds of megabytes and the bandwidth is limited, so fiber optics must be deployed. In the future, gigabit, two gigabit or more bandwidths may be needed. The advantage of fiber optics is that the bandwidth is unlimited and it has a life span of 30 years after deployment. ”

However, Huang Zhiyong mentioned that in the past, the Ministry of Housing and Urban-Rural Development did not have a clear standard for putting optical fiber into the room. Therefore, Huawei is now cooperating with the Ministry of Housing and Urban-Rural Development, hoping to bury optical fibers directly in the rooms in commercial office buildings and residential communities. “The FTTR road requires not only policy support, but also the cooperation of upstream and downstream companies including home improvement companies, operators, Huawei, and real estate developers.”

According to the data, from the perspective of the development of gigabit broadband access services, as of 2020, 70 provincial telecom operators in China have launched gigabit broadband commercial packages; the number of gigabit subscribers in my country has reached 6.43 million, which is higher than that. At the end of the year, there was a net increase of 5.53 million households.

However, “speeding up and reducing fees” is also the focus that the government has always mentioned. Last year’s government work report clearly put forward the requirement of “a 15% reduction in average rates for broadband and dedicated lines”, and this year’s government work report also clearly required that SMEs’ average broadband and dedicated line tariffs be reduced by another 10%.

Under the trend of “speed up and cost reduction”, how can operators and equipment manufacturers make profits? Huang Zhiyong told reporters, “Huawei’s idea is to reduce the transmission cost per bit through a large number of technological innovations on the one hand. On the other hand, to make network construction more efficient through a large number of scenario-based and architectural innovations. One point of view is to’improve quality and speed’, and ultimately transform the previously mentioned demographic dividend into an experience dividend by satisfying the differentiated experience of customers.”

While major operators are investing heavily in the construction of 5G, they must also promote the upgrade of gigabit optical networks. Therefore, in addition to the implementation of gigabit optical network construction and tariff issues, the investment cost of F5G construction is also the focus of attention from the outside world.

Huang Zhiyong said that the investment in the F5G era from F4G, GPON to 10GPON did not increase much, because the most difficult money to spend in the “optical in and copper retreat 1.0” was to unplug the copper wires and deploy optical fibers in the GPON era. The 100M F4G era 80% of the cost has been invested. Therefore, when upgrading from 100M to Gigabit, 80% of the investment does not need to be moved. Only the OLT board and Gigabit optical modem of the central office are upgraded. The F5G Gigabit access investment may be 1/10 or even less than that of 5G.

Exploring “application scenarios” is the key

The wave of 5G is rolling forward, and the current 5G-oriented application exploration for the B-side is also a hot spot. Industry convergence applications are accelerating, while the application exploration of Gigabit optical networks is relatively small compared to 5G. In the development of gigabit optical network, the foundation is under construction and the key is in use. How to promote the innovative application of gigabit optical network is the focus of attention of all parties at present.

Wei Leping, executive deputy director of the Communication Science and Technology Committee of the Ministry of Industry and Information Technology, once said that Gigabit optical network access is not only a supplement to Gigabit 5G access, but even better than 5G in many performance parameters. 5G applicable business scenarios include outdoor mobile scenarios and scenarios where optical fiber is difficult to deploy. The advantages of optical fiber are the coverage of fixed scenarios such as homes, offices, workshops, medical care, and video surveillance, as well as scenarios with high-bandwidth and high-quality networks.

However, the current level of my country’s optical fiber network and 5G network has led the world, and it has entered a “no man’s land” in terms of “dual gigabit” network applications, and is in the stage of concentrated exploration and research.

Jin Yuzhi said that scenarios such as education informatization, medical digitization, and industrial Internet are all application scenarios for Gigabit optical networks: in universities, teaching and life scenarios are responsible, and the number of users is huge; hospitals also face problems such as large amounts of data and high transmission pressure, and In telemedicine, low latency and so on are required.

At the forum, Zhu Suishong, director of the Network Technology Department of Shenzhen Nanshan People’s Hospital, shared the innovative application of “all-optical network” in smart medical care. Zhu Suisong said that after the hospital adopted the “All Optical Park” solution, the network was stable and reliable, and the access time of the medical imaging system was increased from nearly 20 seconds to less than 1 second. At the same time, based on this network, the medical record sharing referral of 89 social health clinics and 5 general hospitals of Xiehe Shenzhen Hospital has been realized.

According to him, an ordinary CT light film is very difficult to understand for most patients, but a complete set of three-dimensional medical images can effectively make patients aware of their condition, but such three-dimensional images require three hundred Only one CT light film can be composed. The blessing of the gigabit optical network has greatly increased the speed of the hospital’s access to the medical imaging system, making it possible to construct more three-dimensional medical images.

In fact, Huawei has been exploring the application scenarios of gigabit optical networks. Huang Zhiyong told reporters, “In to B scenarios, such as mines, in fact, F5G is particularly needed. Because there are many tree-shaped roadways in the mines, it is very difficult to transmit wireless signals in the roadways, and there are flammable and explosive scenes under the coal mine. F5G has a large bandwidth and time The extension is low, and technology based on industrial PON or optical is not possible, which can greatly reduce the number of explosion-proof boxes.”

Huang Zhiyong also mentioned that in some strong electric manufacturing scenes, such as automobile processing and some welding igniting scenes, the charged ones are not as good as the anti-interference effect of optical fiber, which is also suitable for F5G scenes. It is understood that in order to explore more application scenarios, Huawei will launch the “Light Chaser 100” action plan, focusing on education, environment, health, development, production and other 5 areas in the next 5 years, and implement at least 100 gigabit optical networks. Application project.

Ye Songhua said that in the next three years, Guangxi Telecom plans to build 14 cities into “Gigabit Cities” to strengthen the coordinated development of Gigabit optical networks and 5G; Li Zhuangzhi, technical director of Shandong Unicom’s Network Department, also revealed that Shandong Unicom will be Fully open the integration of cloud and light to explore, and combine the needs and characteristics of government affairs, finance, medical, manufacturing and other industries to provide industry solutions.

Construction and landing require the efforts of all parties

In fact, it is not simple to promote the construction of gigabit optical networks in an all-round way.

Jin Yuzhi said that the “secondary reform” put forward two new requirements. First, it is necessary to realize Gigabit home access on the home side, including further upgrading from FTTH to FTTR (Fiber into the room), home Wi-Fi speed to realize Gigabit and so on. Second, on the industry application side, Gigabit optical networks should be used to collaborate with 5G to promote the digital transformation of thousands of industries.

The first is FTTR, which connects optical fibers to every room. Huang Zhiyong, vice president of Huawei’s transmission and access product line, told reporters that neither the twisted pair technology nor the power line technology can carry gigabit bandwidth. “The carrier of the power line is hundreds of megabytes and the bandwidth is limited, so fiber optics must be deployed. In the future, gigabit, two gigabit or more bandwidths may be needed. The advantage of fiber optics is that the bandwidth is unlimited and it has a life span of 30 years after deployment. ”

However, Huang Zhiyong mentioned that in the past, the Ministry of Housing and Urban-Rural Development did not have a clear standard for putting optical fiber into the room. Therefore, Huawei is now cooperating with the Ministry of Housing and Urban-Rural Development, hoping to bury optical fibers directly in the rooms in commercial office buildings and residential communities. “The FTTR road requires not only policy support, but also the cooperation of upstream and downstream companies including home improvement companies, operators, Huawei, and real estate developers.”

According to the data, from the perspective of the development of gigabit broadband access services, as of 2020, 70 provincial telecom operators in China have launched gigabit broadband commercial packages; the number of gigabit subscribers in my country has reached 6.43 million, which is higher than that. At the end of the year, there was a net increase of 5.53 million households.

However, “speeding up and reducing fees” is also the focus that the government has always mentioned. Last year’s government work report clearly put forward the requirement of “a 15% reduction in average rates for broadband and dedicated lines”, and this year’s government work report also clearly required that SMEs’ average broadband and dedicated line tariffs be reduced by another 10%.

Under the trend of “speed up and cost reduction”, how can operators and equipment manufacturers make profits? Huang Zhiyong told reporters, “Huawei’s idea is to reduce the transmission cost per bit through a large number of technological innovations on the one hand. On the other hand, to make network construction more efficient through a large number of scenario-based and architectural innovations. One point of view is to’improve quality and speed’, and ultimately transform the previously mentioned demographic dividend into an experience dividend by satisfying the differentiated experience of customers.”

While major operators are investing heavily in the construction of 5G, they must also promote the upgrade of gigabit optical networks. Therefore, in addition to the implementation of gigabit optical network construction and tariff issues, the investment cost of F5G construction is also the focus of attention from the outside world.

Huang Zhiyong said that the investment in the F5G era from F4G, GPON to 10GPON did not increase much, because the most difficult money to spend in the “optical in and copper retreat 1.0” was to unplug the copper wires and deploy optical fibers in the GPON era. The 100M F4G era 80% of the cost has been invested. Therefore, when upgrading from 100M to Gigabit, 80% of the investment does not need to be moved. Only the OLT board and Gigabit optical modem of the central office are upgraded. The F5G Gigabit access investment may be 1/10 or even less than that of 5G.

Exploring “application scenarios” is the key

The wave of 5G is rolling forward, and the current 5G-oriented application exploration for the B-side is also a hot spot. Industry convergence applications are accelerating, while the application exploration of Gigabit optical networks is relatively small compared to 5G. In the development of gigabit optical network, the foundation is under construction and the key is in use. How to promote the innovative application of gigabit optical network is the focus of attention of all parties at present.

Wei Leping, executive deputy director of the Communication Science and Technology Committee of the Ministry of Industry and Information Technology, once said that Gigabit optical network access is not only a supplement to Gigabit 5G access, but even better than 5G in many performance parameters. 5G applicable business scenarios include outdoor mobile scenarios and scenarios where optical fiber is difficult to deploy. The advantages of optical fiber are the coverage of fixed scenarios such as homes, offices, workshops, medical care, and video surveillance, as well as scenarios with high-bandwidth and high-quality networks.

However, the current level of my country’s optical fiber network and 5G network has led the world, and it has entered a “no man’s land” in terms of “dual gigabit” network applications, and is in the stage of concentrated exploration and research.

Jin Yuzhi said that scenarios such as education informatization, medical digitization, and industrial Internet are all application scenarios for Gigabit optical networks: in universities, teaching and life scenarios are responsible, and the number of users is huge; hospitals also face problems such as large amounts of data and high transmission pressure, and In telemedicine, low latency and so on are required.

At the forum, Zhu Suishong, director of the Network Technology Department of Shenzhen Nanshan People’s Hospital, shared the innovative application of “all-optical network” in smart medical care. Zhu Suisong said that after the hospital adopted the “All Optical Park” solution, the network was stable and reliable, and the access time of the medical imaging system was increased from nearly 20 seconds to less than 1 second. At the same time, based on this network, the medical record sharing referral of 89 social health clinics and 5 general hospitals of Xiehe Shenzhen Hospital has been realized.

According to him, an ordinary CT light film is very difficult to understand for most patients, but a complete set of three-dimensional medical images can effectively make patients aware of their condition, but such three-dimensional images require three hundred Only one CT light film can be composed. The blessing of the gigabit optical network has greatly increased the speed of the hospital’s access to the medical imaging system, making it possible to construct more three-dimensional medical images.

In fact, Huawei has been exploring the application scenarios of gigabit optical networks. Huang Zhiyong told reporters, “In to B scenarios, such as mines, in fact, F5G is particularly needed. Because there are many tree-shaped roadways in the mines, it is very difficult to transmit wireless signals in the roadways, and there are flammable and explosive scenes under the coal mine. F5G has a large bandwidth and time The extension is low, and technology based on industrial PON or optical is not possible, which can greatly reduce the number of explosion-proof boxes.”

Huang Zhiyong also mentioned that in some strong electric manufacturing scenes, such as automobile processing and some welding igniting scenes, the charged ones are not as good as the anti-interference effect of optical fiber, which is also suitable for F5G scenes. It is understood that in order to explore more application scenarios, Huawei will launch the “Light Chaser 100” action plan, focusing on education, environment, health, development, production and other 5 areas in the next 5 years, and implement at least 100 gigabit optical networks. Application project.
