On April 9, SpaceX successfully sent four private astronauts into space using the Falcon 9 rocket and the manned dragon spacecraft. It is expected that the spacecraft will arrive at the international space station on Saturday morning local time < p > the mission, called axiom-1 (AX-1), was carried out by SpaceX in cooperation with commercial aerospace company axiom space. It is the world's first private astronaut mission to the international space station, and SpaceX's second private manned space mission after inspiration 4 < p > it is reported that the Falcon 9 rocket carrying out this mission has previously carried out four space missions, and the Dragon spacecraft carrying astronauts has also carried out two launches. The rocket was successfully launched from Cape Canaveral, Florida, and then the first and second stages were successfully separated. The first stage booster successfully landed on the unmanned recovery ship in the Atlantic Ocean. The manned dragon spacecraft is currently on its way to the international space station and is expected to dock with the international space station at 7:45 a.m. EST on Saturday < p > four astronauts plan to stay on the international space station for about 8 days and conduct a total of 25 scientific experiments totaling 100 hours < p > axiom 1 mission is the first of four space missions planned by axiom space and SpaceX. Axiom space's long-term goal is to build a series of commercial space stations starting from Axiom station. The company plans to dock the first module of axiom space station with the international space station as early as 2024, and finally leave the international space station to establish a free flying independent space station < p > the flight commander of axiom 1 mission is Michael Lopez Alegr í a, a former NASA astronaut and chief astronaut of axiom space. The crew members include Larry Connor, founder of Connor group, a US real estate investment company, mark patty, CEO of mavrik, a Canadian investment and finance company, and former Israeli Air Force pilots Eytan Stibbe, founder of vital capital, an investment fund. Axiom space announced the crew list in January 2021. According to Connor, the crew trained 750 to 1000 hours before and after the mission < p > "congratulations on the launch of Falcon 9," William Gerstenmaier, SpaceX's vice president for manufacturing and flight reliability, told the astronauts after they entered orbit. "Enjoy your space trip. Do some great research for us. We'll see you again on the ground." < p > Lopez Allegria thanked the SpaceX team for putting astronauts into orbit safely. "This is a hell of a journey and we look forward to the next 10 days," he concluded < p > axiom space was silent about the financial situation of the space trip. When the company first released the crew list, it was reported that astronauts spent $55 million on it. Axiom space also paid NASA a fee for the crew to use NASA's various facilities on the international space station. In 2019, NASA announced that the US module of the international space station will open more commercial activities. The cost of NASA's toilet support system was $11250 per person per day The crew of < p > axiom 1 mission mainly work and activities in the US module of the international space station, but they will also visit the Russian module at the invitation of the three astronauts of the international space station. Four private astronauts plan to rest in different parts of the international space station, including two sleeping in the Columbus module, one sleeping in the manned dragon spacecraft docked with the international space station and one sleeping in the airlock < p > although the crew of axiom 1 did not receive the high-intensity training of NASA astronauts before going to the international space station, they mainly learned the basic skills needed to visit the international space station, such as how to eat and how to go to the toilet in the microgravity environment. Dana Weigel, deputy manager of NASA's international space station program, said: "in order to make them comfortable and know how to operate independently on the international space station, we have conducted a lot of daily life training." Members of axiom 1 also received emergency training to prevent a major disaster on the international space station. However, these people are still regarded as guests of the international space station. If they happen to break the toilet while using the toilet, they don't have to repair it < p > after the mission, the crew of axiom 1 will board the manned dragon spacecraft again, leave the international space station and splash into the ocean near the coast of Florida. Subsequently, SpaceX will send three NASA astronauts and one European Space Agency astronaut to the international space station on April 21, and bring the crew-3 astronauts back to earth.
