Dragon is a free-flying spacecraft designed to deliver both cargo and people to orbiting destinations. It is the only spacecraft currently flying that is capable of returning significant amounts of cargo to Earth. Currently Dragon carries cargo to space, but it was designed from the beginning to carry humans. The first demonstration flight under NASA's Commercial Crew Program launched on March 2, 2019 at 2:49 a.m. ET. The Dragon spacecraft successfully docked with the space station ahead of schedule at 6:02 a.m. ET on March 3, 2019, becoming the first American spacecraft in history to autonomously dock with the International Space Station.
