 SpaceX Crew-2 mission patch  McArthur, Pesquet, Hoshide and Kimbrough | |
SpaceX Crew-2 used the same capsule as Crew Dragon Demo-2 (Endeavour) and launched on the same Falcon 9 booster as SpaceX Crew-1 (B1061.1).
With its return to Earth the evening of 9 November 2021, the mission set a record for the longest spaceflight by a U.S. crewed spacecraft, 199 days.
Crew
On 28 July 2020, JAXA, ESA and NASA confirmed their astronaut assignments aboard this mission.

Mission
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).

Wake-up calls
NASA began a tradition of playing music to astronauts during the Gemini program, and first used music to wake up a flight crew during Gemini 6; the first song was Hello, Dolly. Each track is specially chosen, often by the astronauts' families, and usually has a special meaning to an individual member of the crew, or is applicable to their daily activities.
| Flight Day | Song | Artist | Played for | Links |

Return
Due to weather delays and a minor health problem with one of the SpaceX Crew-3 crew, NASA decided to bring home the Crew-2 astronauts from the ISS before launching Crew-3, thus being the first Crew Dragon indirect handover of space station crews. The Crew Dragon undocked from the station at 19:05 UTC on 8 November 2021 and splashed down off the coast of Florida at 03:33 UTC on 9 November 2021. One of four parachutes deployed slower than the others.
