Four Nasa astronauts are to be shot from Earth in a SpaceX rocket.
The mission, named Crew-2, is the third time that Elon Musk’s rocket company has sent a Nasa crew into space in less than a year.
It will be the first time that the Falcon rocket and Dragon capsule that will carry them have been recycled. The capsule took the company’s first crew, in May, and the rocket carried the second one in November.
