Before that, Elon Musk, the founder of SpaceX, had said that the first manned mission would take place around the second quarter of this year, but there was no clear timetable. However, according to media reports, the time will be initially scheduled for May 7 this year.
According to Ars technica, the first SpaceX manned mission is expected to take place on May 7 this year, but there are still some variables, so the launch date may be advanced to the end of April or postponed.
Ars technica has written that NASA is not ready to implement a commercial spacecraft manned plan for the first half of 2020, which may affect SpaceXs manned flight plan. The report drew a direct retort from musk on twitter, saying SpaceX will officially fly in late 2019 or early 2020.
Therefore, the next step is the official manned mission to carry NASA astronauts to the international space station.
NASA has previously announced that two astronauts, Robert Behnken and Douglas Hurley, will participate in the test flight mission, and two other astronauts, Victor Glover and Michael Hopkins, will participate in the first flight mission.
The participation of commercial companies such as SpaceX in NASAs manned space mission is part of NASAs commercial astronaut program, under which SpaceX and Boeing are responsible for manufacturing and launching rockets and capsule carrying astronauts to and from the space station.
In the field of manned space flight, the U.S. has always adopted the way of space shuttle, but twice suffered setbacks: on the morning of January 28, 1986, the space shuttle Challenger exploded and disintegrated in 73 seconds, killing all seven crew members on board; the second was February 1, 2003, when Columbia entered the atmosphere over Texas and Louisiana, but exploded, All seven astronauts were killed.
Two serious explosions forced the United States to abandon the space shuttle mode. The last manned space mission and the last space shuttle mission sts-135 was launched from the Kennedy Space Center in 2011.
Since then, the United States has relied entirely on Russian spacecraft to transport astronauts to and from the international space station. In the future, NASA will use SpaceX and Boeing to re deliver astronauts from the United States to the international space station.
SpaceX, founded by musk in 2002, aims to reduce the cost of space exploration by reusing the first stage rockets and spacecraft. At the same time, musk also proposed the idea of colonizing Mars through SpaceX.
In 2011, NASA awarded SpaceX a commercial manned development contract to develop and test a manned spacexdragon to transport astronauts to and from the international space station. As of February 2019, SpaceX has conducted 16 international space station replenishment missions with NASA.
