SpaceX successfully launched its Crew Dragon spacecraft over the weekend from the Kennedy Space Center in Florida.

The Crew Dragon is the first commercially built and operated American crew spacecraft to leave Earth. It arrived safely at the International Space Station, where it's expected to stay docked for five days before returning to our home planet. 

The flight is expected to bring NASA one step closer to sending humans back into space, which hasn鈥檛 been done in nearly a decade.
