This is the first manned space flight from the United States in nine years.
This will be the first manned space flight from the United States to the orbiting laboratory since 2011.
The tech entrepreneur-owned company will launch a Falcon 9 rocket that will carry astronauts Bob Behnken and Doug Hurley at a time when the space Agency is trying to cut costs.
“Currently, NASA and SpaceX assume that the launch will take place no earlier than mid-late May,” the aerospace Agency said in a statement.
In March last year, the Crew Dragon spacecraft lander with a dummy on Board made a flight to the orbital station, which is located 400 kilometers from Earth. After six days in space, it landed in the Atlantic Ocean.
