On September 12, according to foreign media reports, American space exploration technology company SpaceX is about to use its manned dragon spacecraft and Falcon 9 rocket to send the first group of purely ordinary people into space for a three-day space trip around the earth. In order to enter space, the four crew members received up to five months of high-intensity training, including climbing snow mountains, conducting 30 hours of simulation flight in the manned dragon spacecraft, and taking a plane to experience zero gravity flight < p > < / P > < p > figure: the four members of SpaceX's first pure commercial manned mission are Chris sambroski, Haley asino, Jared Isaacman and Sean Proctor from left to right < / P > < p > the flight is called inspiration4, and the crew includes the billionaire Jared Isaacman who paid for the mission Hayley Arceneaux, assistant doctor, Chris sembroski, engineer, and Sian Proctor, earth scientist. They will fly around the earth for three days, enjoy the scenery and collect data for scientific research, then land vertically in the atmosphere and safely with the help of parachutes < p > in the past five months, the crew has been training, learning various operation manuals, pushing their bodies to the limit and preparing for the worst. This week, they finally completed the training program developed by NASA. Although Isaacman has thousands of hours of experience flying jets and former military aircraft, he admits that astronaut training is "more intense" than he expected < p > when Amazon founder Jeff Bezos and British billionaire Richard Branson took rockets to the edge of space (not into orbit) Neither of them disclosed the details of their training. However, the crew of inspiration 4 always openly shared their preparations, so that people could have a glimpse of what amateurs need to do for space flight. < / P > < p > the following is what they revealed: < / P > < p > ● & nbsp; when the crew of inspiration 4 mission was screened, the first thing they did together was Is to watch SpaceX launch the third batch of commercial astronauts to the international space station. < / P > < p > ● & nbsp; feel the centrifuge during training. The centrifuge rotates very fast and can generate centrifugal force to push things outward. When the pull of gravity on the body reaches three times the normal force, this force will feel the launch. < / P > < p > < / P > < p > ● & nbsp; the four climbed together in early May Mount Rainier, an active volcano with a height of about 4400 meters. < / P > < p > ● & nbsp; after climbing Mount Rainier, the crew flew to SpaceX headquarters in Hawthorne, Ga., and began to seriously receive 12 hours of training every day. They must have a good understanding of the components of Falcon 9 rocket and manned dragon spacecraft, how they work, and what problems may occur. < / P > < p > ● & nbsp; in a simulated carrier In the Dragon spaceship model, the crew of inspiration4 practiced the launching and landing procedures. When they got used to how things should work when everything went well, the trainers began to add problems and spacecraft faults to the simulation. < / P > < p > ● & nbsp; experience weightlessness in parabolic flight. In parabolic flight, the aircraft will fly up and down in an arc and in an arc The peak of the shape produces weightlessness for up to 30 seconds. < / P > < p > ● & nbsp; because scientists want more information about how space flight affects the body, the inspiration4 crew volunteered to collect biological data for NASA. In addition to collecting each other's blood and skin samples, the crew will also monitor their sleep status, conduct daily cognitive tests on iPads, and use ultrasound The equipment scans their organs. < / P > < p > ● & nbsp; during the training, the inspiration4 crew made public appearances, accepted media interviews and visited the space camp. < / P > < p > ● & nbsp; after the training, Isaacman, Proctor and asino sambroski flew to the Kennedy Space Center in Florida last Thursday to complete the final preparations before the launch.
