NASA gave its final go-ahead on Friday to billionaire entrepreneur Elon Musk’s SpaceX company to conduct its first unmanned test flight of a newly designed crew capsule to the International Space Station on March 2.

NASA has awarded SpaceX $2.6 billion and Boeing Co $4.2 billion to build rocket and capsule launch systems to return astronauts to the orbiting research laboratory from U.S. soil for the first time since America’s space shuttle program ended in 2011.
