SpaceX Crew-1 (was also known as USCV-1 or simply Crew-1) was the first operational[b] crewed flight of a Crew Dragon spacecraft, and the maiden flight of the Crew Dragon Resilience spacecraft. It was also the second crewed orbital flight launch by the United States since that of STS-135 in July 2011. Resilience launched on 16 November 2020 at 00:27:17 UTC on a Falcon 9 from Kennedy Space Center Launch Complex 39A (LC-39A), carrying NASA astronauts Michael Hopkins, Victor Glover and Shannon Walker, along with JAXA astronaut Soichi Noguchi, all members of the Expedition 64 crew. The mission was the second overall crewed orbital flight of the Crew Dragon.

Crew-1 was the first operational mission to the International Space Station (ISS) in the Commercial Crew Program. Originally designated "USCV-1" by NASA in 2012, the launch date was delayed several times from the original date of November 2016. The mission was scheduled to depart the ISS on 28 April 2021, but due to weather returned to Earth on 2 May 2021. The capsule splashed down at 06:56:33 UTC, to be reused on Inspiration4. It was the first nighttime splashdown for NASA astronauts since Apollo 8 in 1968. On 7 February 2021, the Crew-1 broke the record for the longest spaceflight by a U.S. crewed vehicle, surpassing the 84-day mark set by an Apollo capsule on the final flight to the Skylab (Skylab-4) space station on 8 February 1974.

The second SpaceX operational mission in the Commercial Crew Program launched on 23 April 2021. The Crew Dragon Endeavour docked to the International Docking Adapter (IDA) at the forward port of the Harmony module. This was the first mission with astronauts on board to use a previously flown booster launch vehicle.

All crew members were veteran astronauts, though this was Megan McArthur's first visit to the ISS (as her first spaceflight was STS-125, a mission to the Hubble Space Telescope). McArthur used the same seat on the Crew Dragon Endeavour which her husband, Bob Behnken, used on the Demo-2 mission. Akihiko Hoshide served as the second Japanese ISS commander during his stay. It was the second mission by Thomas Pesquet to the International Space Station and was named Alpha, after Alpha Centauri, the closest star system to Earth.

To prepare for the arrival of a Starliner, the Endeavour docked to ISS at Harmony forward port was undocked at 10:45 UTC and relocated to Harmony zenith port on 21 July 2021, at 11:36 UTC.

With CRS-23, (C208) and Inspiration4 (Resilience), three Dragon spacecraft were in space at the same time, from 16 to 18 September 2021 (UTC).
