SpaceX CRS-21, also known as SpX-21, was a Commercial Resupply Service mission to the International Space Station which launched on 6 December 2020.[1][2] The mission was contracted by NASA and was flown by SpaceX using a Cargo Dragon 2. This was the first flight for SpaceX under NASA's CRS Phase 2 contract awarded in January 2016. This was also the first Cargo Dragon of the new Dragon 2 variant, as well as the first Cargo Dragon flight that is docked at the same time as a Crew Dragon spacecraft (SpaceX Crew-1).
This mission used Booster B1058.4, becoming the first NASA mission to reuse a booster previously used on a non-NASA mission. This was also first time SpaceX launched a NASA payload on a booster with more than one previous flight. Before the heading for re-entry, the automated cargo capsule undocked from the International Space Station (ISS) on 12 January 2021 at 14:05 UTC. The new Dragon design can automatically dock and undock at the station, while the first-generation Dragon cargo freighters were grappled by the station's robotic arm.
The undocking and splashdown marked the first return of a Cargo Dragon spacecraft, and wrapped up the first flight of SpaceX Dragon 2 supply spacecraft derived from the Crew Dragon spacecraft. SpaceX recovery teams were on standby for the parachute-assisted splashdown on 14 January 2021 at 01:26 UTC in the Gulf of Mexico, at west of Tampa, Florida.
The Dragon returned to Earth with 2,002 kg (4,414 lb) of cargo, according to NASA. SpaceX plans to reuse the Cargo Dragons up to five times. The new Cargo Dragon spacecraft can haul about 20% more cargo volume than previous Dragon supply ships. It was launched without seats, cockpit controls, the life support system required to sustain astronauts in space and SuperDraco abort engines.
