NASA astronauts are slated to launch a rocket to the International Space Station Wednesday afternoon, marking the first manned space mission since the shuttle program was retired in 2011.
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.
In case of a postponement, NASA and SpaceX might try again on Saturday or Sunday afternoon.
The mission will be the first time that SpaceX will transport people, and not cargo, to outer space.
