Crew Dragon Demo-1

These photos show the 215-foot-tall Falcon 9 rocket and Crew Dragon spacecraft at launch pad 39A, ready for liftoff from Florida’s Space Coast on a critical test flight to the International Space Station.

SpaceX rolled the first Crew Dragon spacecraft out to a Florida launch pad Thursday for final preparations ahead of a test flight to the International Space Station.

SpaceX’s first Crew Dragon spacecraft, fixed to the forward end of a Falcon 9 rocket, emerged Thursday from the company’s hangar at the Kennedy Space Center in Florida for the quarter-mile journey to its launch mount at pad 39A, where liftoff is scheduled early Saturday on a critical test flight before astronauts strap into the ship later this year.

The first official launch weather outlook issued Tuesday by U.S. Air Force meteorologists predicts an 80 percent chance of favorable conditions for the predawn liftoff Saturday of SpaceX’s Crew Dragon spacecraft on a test flight to the International Space Station.
