NASA astronauts Douglas G. Hurley and Robert L. Behnken are the duo traveling in the rocket; they will launch from Kennedy Space Center in Florida.
NASA astronauts will try again to blast off to the International Space Station Saturday afternoon, after inclement weather scrubbed a launch Wednesday.
If successful, Saturday’s takeoff will mark the first crewed space mission since the shuttle program was retired in 2011.
The mission will be the first time that SpaceX will transport people, and not cargo, to outer space.
