 SpaceX CRS-21 mission patch | |
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 was 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.[7][8]
