Falcon 9’s first stage booster previously supported launch of SpaceX’s 19th and 20th cargo resupply missions to the International Space Station, a Starlink mission, and the SAOCOM 1B mission. Following stage separation, SpaceX will land Falcon 9’s first stage on Landing Zone 1 at Cape Canaveral Space Force Station in Florida.
