The main purpose of constellation plan

Constellation is an American space program and the latest name of NASA's return to the moon program. Four years ago, President Bush asked Americans to return to the moon and fly to Mars. Therefore, NASA has spent hundreds of millions of dollars to design, build and test spacecraft that can make this plan possible. However, this effort did not attract public interest like the Apollo program in the 1960s. In early 2009, NASA asked an advertising company in new york to "officially name" the project, calling it "Constellation Project". The plan undertakes the task of building and launching spacecraft. It is also the ground support system of this period. Without it, the United States will not be able to realize its plan to build a lunar outpost. The plan will adopt a new generation of spacecraft, such as a new manned spacecraft, a new launch vehicle and a landing module, including the construction of Ares 1 rocket and Orion spacecraft.

At a recent press conference, NASA officials in charge of the Constellation Project denied the above accusations of the Aviation Safety Advisory Group, saying that there was no safety design problem in NASA, and they would not disclose whether the astronauts were anxious. According to the plan, Orion spacecraft will replace the space shuttle which is expected to retire in 20 10. The first launch time of the spacecraft is about 20 15. According to the constellation plan, Orion spacecraft will send astronauts and cargo to the space station, rendezvous with the lunar module and the earth departure station in low-earth orbit, and send astronauts to the moon; It will also play a role in the exploration of Mars. At the same time, it is also an aircraft that returns to Earth from the moon and Mars, and will become the main carrier for NASA to transport astronauts to the International Space Station and the moon in the future. In the report, NASA's aviation safety advisory group stressed that in the past, when NASA built a spacecraft, it would pay attention to building enough backup safety systems from the beginning of the plan, "to ensure that the spacecraft has sufficient safety and reliability." However, due to the weight problem in the design of Orion spacecraft, NASA adopted different methods and did not include all safety measures from the beginning.
