Historic SpaceX astronaut launch postponed to Saturday

On Wednesday, NASA was preparing to send two of its astronauts to orbit aboard a spacecraft built by SpaceX, the rocket company founded by Elon Musk. And unlike for astronaut launches in the past, when NASA ran the show, this time SpaceX will be in charge of mission control.
