On August 23, according to foreign media reports, the first pure commercial manned space mission inspiration4 of American space exploration technology company SpaceX will be launched on September 15. Before that, the four members participating in the mission were receiving high-intensity training, including snow trekking, weightlessness test and survival in water < p > < / P > < p > even for healthy people, it is quite difficult to complete these trainings, not to mention Hayley Arceneaux, a 29 year old bone cancer survivor. As the youngest crew member of the mission, alceno will make a new history and become the first person to carry a prosthetic into space < p > alceno, from Baton Rouge, Louisiana, is now a doctor assistant at St. Jude's children's Hospital, where she was treated for bone cancer. In a recent interview, she talked about her training. He explained that the preparation process began a few months ago, shortly after the names of the four crew members were announced < p > the training began in Pennsylvania, where alceno and her companions experienced the great pressure that the body will experience in space flight < p > alceno said: "once the identities of the four crew members were announced, we went directly to Pennsylvania for centrifuge training to adapt our bodies to the gravity we would feel during launch and re-entry into the atmosphere." She added that the intensity of training has really increased in recent weeks < p > in centrifuge training, the crew is designed to ride a device that looks like a roller coaster. It rotates very fast. The purpose is to train the crew's body to get used to the acceleration and gravity they will experience when they leave the earth's surface < p > alceno said that since then, we have studied a lot, spent a lot of time on the simulator, and done a lot of cool things < p > the first thing the crew did together was to climb Mount Rainier in Washington on foot to "break the deadlock and establish a chemical reaction". Alceno recalled their commander's words, saying it was to "let us adapt to uncomfortable feelings" < p > alceno said: "we camped on this mountain for three days. On the first day, we went straight up the mountain and climbed for 10 hours on foot. We know a lot about ourselves and each other, which makes us more confident in completing the task. We get along very well. " < p > she said in an interview: "we also conducted a zero gravity flight and experienced the feeling of weightlessness for the first time." She described being in a spaceship without gravity as "the strangest feeling of not being attached to anything", adding that flying in weightlessness was harder than expected < p > then, the crew participated in altitude training to prevent emergencies, such as the decline of oxygen level caused by cabin pressure failure. "We also conducted some survival training in water and hypoxia training, all of which are typical astronaut training," she said. These experiences are unforgettable and feel great! " < p > the four members of inspiration 4, from left to right, are Chris samboski, a 41 year old veteran of the Iraq war, Sean Proctor, a 51 year old professor of Earth Sciences, Jared Isaacman, a billionaire, and alceno < / P > < p > alceno said: "there are too many moments that make me feel unreal, but when I put on my spacesuit two weeks ago, I can say, 'yes, I'm an astronaut. I'm going to space! " The crew even conducted a 30 hour simulation to understand what the several-day trip would look like, including how to eat space food and wear space suits < p > alceno also said: "then I really saw the Falcon 9 rocket. It's so exciting. We have to sign the soot because it has been launched several times. The beauty of SpaceX is that they are developing this reusable technology, so this rocket has been to space. It has soot on its surface. We must sign on the soot. " < p > alceno showed her instagram fans what she had prepared for space, including her late father's favorite tie, a alma mater T-shirt, parents' wedding ring and other special souvenirs. "I brought photos of friends who died of cancer over the years because they are an important part of our mission (and raising money for the hospital)," she said < p > alceno is a doctor's assistant at St. Jude's children's research hospital, where she was treated for bone cancer at the age of 10. The Hospital replaced part of her right femur with a metal rod. In 19 years, the prosthesis will make her the first person to orbit the earth with an artificial body part < p > alceno recalled that she first wanted to be an astronaut a few months before she was diagnosed with bone cancer. At that time, her family took her to visit NASA in Houston. After joining the inspiration 4 unit with billionaire Jared Isaacman, she is now less than a month away from realizing this dream. Isaacman paid for the space flight in February < p > alceno wants her young patients and other cancer survivors to know that "the sky is no longer even the limit". She looked forward to the life changing moments experienced by astronauts looking back on earth in space, but she said that calling patients at St. Jude Children's Hospital from space was the most exciting thing for her < p > she said: "children's ideas are very intuitive, which will actually show them what their future will be like. I really just want to send this message: if I can do it, you can do it. I hope there will be better days. Your hair will grow out, you will feel better, you will grow up and realize your dreams.
