SpaceX CRS-23, also known as SpX-23, is a Commercial Resupply Service mission to the International Space Station planned to be launched NET August 18, 2021. The mission is contracted by NASA and will be flown by SpaceX using a Cargo Dragon. This will be the third flight for SpaceX under NASA's CRS Phase 2 contract awarded in January 2016.
SpaceX plans to reuse the Cargo Dragons up to five times. The Crew Dragon capsules, used on missions with astronauts, are not planned to be initially reused. The Cargo Dragon will launch without SuperDraco abort engines, without seats, cockpit controls and the life support system required to sustain astronauts in space. This newer design provides several benefits, including a faster process to recover, refurbish and re-fly versus the earlier Dragon CRS design used for ISS cargo missions.
The new Cargo Dragon capsules under the NASA CRS Phase 2 contract will splash down under parachutes in the Atlantic Ocean, east of Florida, rather than the previous recovery zone in the Pacific Ocean west of Baja California.
Deployable Space Systems' Solar Arrays, with new XTJ Prime space solar cells, will be the second pair delivered to the station in the unpressurized trunk of SpaceX Dragon cargo spacecraft during this resupply mission. The First Pair will be delivered on CRS-22 and the Final Pair will be delivered on CRS-24. The installation of each new solar array will require two (2) spacewalks: one to prepare the worksite with a modification kit and another to install the new panel.
The new experiments arriving at the orbiting laboratory will inspire future scientists and explorers, and provide valuable insight for researchers.
