Crew Dragon Demo-2 (officially Crew Demo-2, SpaceX Demo-2, or Demonstration Mission-2) was the first crewed test flight of the Crew Dragon spacecraft. The spacecraft, named Endeavour, launched on 30 May 2020 at 19:22:45 UTC (3:22:45 PM EDT) on top of Falcon 9 Booster B1058.1, and carried NASA astronauts Doug Hurley and Bob Behnken to the International Space Station in the first crewed orbital spaceflight launched from the United States since the final Space Shuttle mission, STS-135, in 2011, and the first ever operated by a commercial provider. Demo-2 was also the first two-person orbital spaceflight launched from the United States since STS-4 in 1982.
Demo-2 was intended to complete the validation of crewed spaceflight operations using SpaceX hardware and to receive human-rating certification for the spacecraft including astronaut testing of Crew Dragon capabilities on orbit. During their time aboard, Behnken conducted four spacewalks with fellow American astronaut Chris Cassidy to replace batteries brought up by a Japanese cargo vehicle.
Docking and undocking operations were autonomously controlled by the Crew Dragon, but monitored by the flight crew in case manual intervention became necessary. The spacecraft soft docked with the International Space Station at 14:16 UTC on 31 May 2020. Following soft capture, 12 hooks were closed to complete a hard capture 11 minutes later. Hurley and Behnken worked alongside the crew of Expedition 63 for 62 days. Endeavour autonomously undocked from the station at 23:35 UTC on 1 August 2020 and returned the astronauts to Earth on 2 August 2020 in the first water landing by astronauts since 1975.
