Postpone it again! SpaceX's second commercial manned spaceflight will be carried out as early as April 22

　　China News Service, March 9th. According to a Reuters report, NASA said that the second commercial manned space mission of SpaceX's Crew Dragon spacecraft was postponed again for two days. It will not take place earlier than April 22.

　　SpaceX is the private rocket company of billionaire entrepreneur Elon Musk.

The company previously planned to perform a second commercial manned space mission at the end of March to deliver a second space station team for NASA.

But NASA announced in January that the target date had been postponed to April 20.

　　A NASA spokesperson said on March 8 that based on orbital mechanics, NASA adjusted the schedule again based on the available flight time to the space station to minimize the sleep requirements of the astronauts.

　　This will be the second complete rotation of space station personnel performed by a private company.

The 4 astronauts on board the "Crew Dragon" include 2 NASA astronauts, 1 Japanese Space Agency astronaut and 1 European Space Agency astronaut.

They will stay on orbit for 6 months.
