SpaceX has completed the last test of a crew capsule before it launches NASA astronauts from the United States.
The US aerospace manufacturer mimicked a launch failure off the Florida coast.
It was testing whether the capsule could separate from a rocket and carry the crew home if something went wrong.
SpaceX founder Elon Musk says it was a picture-perfect mission.
