Since the suspension of the American Space shuttle STS in 2011, the manned of the Earth and the International Space Station (ISS) has to rely on the Russian manned spacecraft alliance Soyuz.Traveling on the earth and ISS to transport materials and equipment, but the manned space shuttle still cannot get rid of Russia's Soyuz old man, but it is helpless to the United States who holds space -sazate.

To this end, NASA, the US Space Agency NASA, has opened the Rumman Space shuttle outsourcing plan Commercial Crew Program, referred to as CCP, and has approved 14 U.S. companies to participate. In 2014, CCP packed $ 4.2 billion to the Boeing Star route Starlineer and 2.6 billionThe dollar developed Dragon Starship, a manned Dragon Star Ship to SpaceX.The purpose of CCP is to build a manned space shuttle of the ISS of the Earth and the International Space Station in the United States, and conduct a first flight test in 2020. It is also the corresponding preparation for the United States to carry on the moon in 2024.Essence

Unfortunately, the development of manned space shuttle in Boeing and SpaceX is not smooth. First, SpaceX occurred during the star boat frozen pressure test on November 20, and then Boeing manned space shuttle for the first time on December 20 (When unpopular) ISS of the International Space Station, failed to dock with ISS and returned without merit.Although Boeing claims to be a low -level error in execution, and landing on the earth's land landing is also a major success (NASA requires that the spacecraft needs to be reused multiple times, so it is difficult to recycle the water that the United States is good at), but in the eyes of public eyes,This high -profile first flight test has made NASA embarrassing. At a press conference for about 2 hours after the spacecraft returned to the press conference, the Director of General NASA spoke some face words, but the first flight test of Boeing was not available.Has made three calls with the US Vice President of the United States.

The failure of the aerospace is the mother of his success, but from a certain level, these two accidents are not coincidental, which seems to mean that the implementation of its big plan has declined.
