Us “space shuttle” officially set sail! SpaceX manned “dragon” SpaceX launched successfully

Beijing, November 16 (Xinhua) at 19:27 local time on the 15th, in the night of Florida, the United States, accompanied by a huge roar, four astronauts carried a manned “dragon” spacecraft developed by the US space exploration technology company, and launched from the Kennedy Space Center. This is the second manned launch of the “dragon” spacecraft and the first commercial manned space mission of this type of spacecraft after it has been certified by NASA, which means that the “space shuttle” of American astronauts is expected to be on the right track. The commercial space age of the United States is about to open. Compared with the historic manned trial in May, this mission means that the U.S. manned space launch is moving toward “routine”. This space journey can be roughly divided into four steps. < / P > < p > launch – at 19:27 U.S. Eastern time on November 15, at Kennedy Space Center, the “dragon” spacecraft was launched on a “Falcon 9” rocket developed by SpaceX. < / P > < p > separation – about 3 minutes after liftoff, the “dragon” spacecraft completed the separation of the first stage rocket, and the recoverable rocket landed on the recovery ship in the Atlantic Ocean; about 12 minutes later, the spacecraft separated from the second stage rocket and entered the predetermined orbit. < / P > < p > docking – the spacecraft will dock with the international space station at about 23:00 on the 16th. The four astronauts on board will become members of the expedition 64 scientific research and experimental task force, and will start a six-month space exploration tour. < / P > < p > return journey – it is expected that in May 2021, the “dragon” spacecraft will take astronauts away from the international space station and return to earth in the form of “parachute splash down”. Data map: on August 2, 2020 local time, the “dragon” spacecraft splashed down in the Gulf of Mexico near Florida in the southeast of the United States, completing the first manned flight test mission. According to reports, the most important feature of the manned “dragon” spacecraft is the use of the first new launch escape system. In order to ensure the safety of astronauts, the designer has equipped 8 “super dragon” engines for the spacecraft. If the spacecraft is in danger during the launch, the eight engines will immediately start to push the spacecraft away from the Falcon 9 rocket and send it to a safe place to land. The manned “dragon” spacecraft is 8.1 meters high and about 4 meters in diameter. Its uplink payload is 6000 kg and its downlink payload is 3000 kg. It can accommodate up to seven astronauts at the same time. The payload is much higher than that of traditional spacecraft. < p > < p > according to the design index, a manned “dragon” spacecraft can be reused for about 10 times, and can carry out low-cost, operational manned space missions in low earth orbit. In addition to sending astronauts to the space station, the modified “dragon” spacecraft can also carry out the mission of landing on the moon. < / P > < p > compared with the cargo version of the “dragon” spaceship, the manned version of the “dragon” spacecraft has added seats, windows, touch screen console, environmental control and life support system, which is more convenient for astronauts to operate. In addition, the overall design style of the spacecraft is minimalist and aesthetic, which is “a bit like a science fiction blockbuster”. It is reported that the manned “dragon” spacecraft is the 9th manned spacecraft in the world and the 5th manned spacecraft in the United States, and it is also the first manned spacecraft independently developed by a private company in the world. Its success not only means that SpaceX has been far ahead in the competition with Boeing and virgin, but also means that the global manned space activities are entering the era of commercialization. The success of the Dragon spacecraft has also given NASA a sigh of relief. In 2011, NASA had to rely on the Russian Soyuz for manned space activities after the decommissioning of the space shuttle developed by the United States. Over the years, NASA has paid Russia a total of $4 billion in “rent” to use its seats on the Soyuz. “We are using American rockets and spacecraft to return to the U.S. for routine manned space launch activities,” NASA director brydenstein said in an effort to certify the safety of the Dragon spacecraft According to the official websites of NASA and SpaceX, the astronauts named the “dragon” spacecraft “tenacity” in view of a series of challenges facing people in 2020, that is, they perform well or can overcome adversity in the face of pressure. This is a necessary quality for aerospace workers. You know, the exploration of the universe has never been smooth sailing. The “dragon” spacecraft from the beginning of research and development to the successful flight test, also experienced a long and tortuous process. < / P > < p > Image: on August 1, 2020, SpaceX’s first manned test flight begins the final phase of the mission – return to earth. The picture shows the separation of the Dragon spacecraft from the international space station. < p > < p > in 2014, NASA commissioned Boeing company and space exploration technology company to build “starplane” and manned “dragon” spacecraft respectively. However, the first flight time of the two spaceships has been postponed many times from the original plan of 2017. It was not until March 2019 that SpaceX completed its first unmanned test flight of the Dragon spacecraft. According to the plan, SpaceX should have sent US astronauts to the international space station in July of that year. However, on April 20, the spacecraft was almost completely destroyed in a static fire. The manned space program has been postponed again. On the afternoon of May 27, 2020, just 10 minutes before the scheduled launch time of the first manned trial voyage, the launch of the “dragon” spacecraft was cancelled due to weather reasons. It was not until May 30, 2020, that the launch of the “dragon” spacecraft was finally successfully launched. < / P > < p > the astronauts carrying out the manned space mission took a group photo in front of the Dragon spacecraft.

Image source: SpaceX official website < / P > < p > in this mission, four astronauts will be sent to the international space station, including NASA astronauts Michael Hopkins, Victor Glover, Shannon Walker and Japanese astronaut tsuichi Noguchi. As the commander of the mission, Hopkins spent 166 days in space and completed many spacewalks. Glover was the pilot and deputy commander of the mission. Walker is a female astronaut who has worked in space for nearly 4000 hours. Japanese astronaut tsuichi Noguchi is also very experienced, this is his third time in a spacecraft into space. < / P > < p > it is worth mentioning that in this mission, the astronauts’ clothes are also very “cool” – the spacesuit is a set of compact lines, the helmet is also 3D printed, gloves and touch screen function. The BBC said it was thanks to Fernandez, a famous Hollywood fashion designer. He has been involved in the design of Batman, X-Men and Raytheon films. However, with the continuous development of space technology, ordinary people’s “space dream” is no longer far away. In the future, SpaceX can sell tickets to almost everyone who wants to go to space. According to reports, Japanese billionaire youzuo Maezawa will become SpaceX’s first tourist to fly around the moon. At the end of July this year, Virgin Galactic also disclosed the cabin design of its commercial spaceship, spaceship2. It is estimated that after the spacecraft is put into service, it can carry six trained passengers into space each time, with a flight range of about 90 minutes and a flight price of about 250000 US dollars. It is reported that about 700 people have already reserved the space travel, and many of them have paid full deposit. Video Number assistant internal test online!
