On February 15, according to foreign media reports, American billionaire Jared Isaacman entered space on SpaceX's manned dragon spacecraft last year, and he plans to complete the same feat again. On Monday, local time, Isaacman announced that he had purchased three other flight opportunities from SpaceX. This series of manned missions called "Polaris project" will help him enter more distant space < p > < / P > < p > Isaacman made a fortune by founding the payment processing company shift4 payments, and funded the SpaceX manned mission called inspiration 4 last September. In addition to himself, the other three lucky people entering space are ordinary people, including a cancer survivor, an engineer and a university professor. While raising funds for the St. Jude Children's research hospital, the four received basic training, finally went into orbit and completed a three-day space trip < p > now, Isaacman seems to plan to reproduce his "inspiration" mission on an increasingly large scale. The three flights he purchased include two missions performed by SpaceX manned dragon spacecraft, which will fly to ultra-high orbit around the earth. These missions will eventually help SpaceX's new starship realize its first manned flight. "The Polaris program is an important step forward in human space exploration and helps solve problems through the use of innovative technologies on earth," Isaacman said in a statement < p > in the first manned dragon spacecraft flight called "Polaris dawn", Isaacman himself plans to participate in the flight again. The other three are two employees of SpaceX, Sarah Gillis and Anna Menon, as well as Scott "Kidd" Poteet, a former Air Force pilot and former Mission Director of inspiration IV. The flight will also be another fundraising event for St. Jude Children's research hospital < p > if the plan goes well, SpaceX's manned dragon spacecraft will fly to its highest altitude ever. Isaacman said in an interview that the Polaris dawn program would be "farther into space than we have been since we last landed on the moon". So far, the manned dragon spacecraft has only flown back and forth between low earth orbits. Its main purpose is to pick up astronauts for NASA and deliver supplies to the international space station. SpaceX launched NASA's first astronauts in May 2020, followed by several launches. However, the company has begun to expand its business, completed the first pure commercial manned mission in history, inspiration 4, and plans to help axiom complete multiple shuttle missions to and from the international space station The flight of the manned dragon spacecraft is to test the prelude mission of SpaceX deep space human travel while trying some new functions. Polaris dawn will include a spacewalk, the first commercial spacewalk ever conducted by a non professional astronaut. The mission executor will wear a new spacesuit specially designed for spacewalk. At present, SpaceX is developing the pressure suit worn by the astronauts on the manned dragon spacecraft < p > in addition, the flight will also test the "space laser communication" capability of SpaceX satellite chain network, which is building a huge Satellite Internet to provide global broadband coverage services. The mission will also investigate how the crew respond to the environment of more distant space, as the flight will take four crew members across the "Van Allen belts", a region of radioactive particles trapped in the earth's magnetic field and extending deep into space. The crew will take the opportunity to collect data on the impact of exposure to space radiation on human health < p > the crew of "Polaris dawn" gave more details at the press conference announcing the above news, but they did not provide the specific altitude of the flight, but said they wanted to go to the highest earth orbit ever flown by humans. "If you understand Gemini's mission, you will have a concept of goals," Isaacman said The main task of Gemini program is to research and develop manned lunar landing technology, and train astronauts' ability to fly for a long time and extravehicular activities < p > the record is currently 1373 kilometers, set by Gemini 11 astronauts Charles "Pete" Conrad and Richard "Dick" Gordon in 1966. Although Apollo astronauts, including Conrad and Gordon, later flew farther away from the earth on lunar missions, the Gemini 11 record is still considered to be the highest earth orbit reached by astronauts today < p > when asked about the development progress of spacesuits for spacewalk, the crew did not disclose the specific situation. "It's really exciting to have a team of talented engineers working on space suits and work together as their design unfolds. We'll share more details with you when the time comes," Menon said < p > although the spacewalk candidate for this mission has not been finalized, the team said that in order for the spacewalker to leave the manned dragon spacecraft, he or she must leave through the open hatch, which will expose other astronauts to the vacuum of space. "There's no airlock, so our whole team of four will be in a vacuum. We'll make sure it's safe enough," Menon said < p > although the crew did not explain how to ensure "safety", it is speculated that when the cabin door is opened, the remaining three crew members will also wear some SpaceX developed spacesuits. So far, SpaceX has an iconic black-and-white pressure suit that astronauts will wear during the launch and re-entry of the manned dragon spacecraft in order to ensure the safety of astronauts in the event of a sudden decompression event. These spacesuits shouldn't have been worn during a spacewalk, but they can still keep astronauts alive in a vacuum for some time < p > as for the budget, Isaacman did not disclose how much he would spend on this mission, but said that the "Polaris" project was a joint investment between him and SpaceX. "We know the cost of going to space is very high. But then the cost will fall, just as they use any other breakthrough technology," Isaacman said < p > so far, the goal of the Polaris dawn mission is to launch in the fourth quarter of 2022, and more details of other missions will be released one after another. The second Polaris mission will be based on what the crew and SpaceX learned on the first mission. In the end, thisThese flights will peak with the first manned launch of a starship. Starship is a giant spacecraft that SpaceX has been developing over the past few years. It aims to send a large number of crew to the moon and eventually bring it to Mars. Isaacman said he might also be involved in two subsequent tasks. "If we achieve our goal in Polaris dawn and will not disappoint, I will have the opportunity to participate in future follow-up missions," he said < p > Isaacman may still be waiting to participate in the manned mission of the interstellar spacecraft, but the spacecraft is still under development and has not even entered space. In 2020 and 2021, SpaceX conducted several high-altitude flight tests on the starship, sent the aircraft to an altitude of nearly 10000 meters, and then tried to land it safely on the ground. In these tests, the Starship landed successfully only once and did not explode < p > SpaceX is trying to get the Starship into orbit sometime this year, but its test flight depends in part on whether the Federal Aviation Administration (FAA) approves SpaceX to launch the Starship from the company's launch facility in southern Texas. The FAA was expected to make a decision by the end of this month, but the agency said on Monday that it would extend the deadline to the end of March < p > even if SpaceX does send a starship into space this year, the company still has a lot to do before sending a manned spacecraft into deep space. SpaceX must develop life support systems, figure out how to replenish propellant for aircraft in space, and show how it can return humans from deep space to earth. The company may take years to develop < p > with the development of StarCraft, SpaceX continues to attract customers for the spacecraft. Last year, NASA awarded SpaceX a $2.9 billion contract to help develop a starship version of the lunar manned lander to send its astronauts to the lunar surface < p > another billionaire and Japanese entrepreneur youzuo Maezawa also purchased the SpaceX starship for a manned space mission called "Dear moon". He will fly around the moon with eight other artists on this aircraft. Just a few days ago, SpaceX CEO Elon Musk updated the latest news on starship development in boccachica, Texas. "There will be many announcements in the future that I think people will be very excited about. But anyway, it will be a very exciting future."
