Starlink Group 4-18

B1052's fifth mission - its third as a converted Falcon 9 first stage - carried 53 v1.5 Starlinks into the 53.2° shell.

B1052 began as a Falcon Heavy Block 5 side booster, flying the Arabsat-6A and STP-2 missions in 2019. SpaceX later converted it for Falcon 9 service, replacing its nosecone with a Falcon 9 interstage and fitting landing legs; it returned to flight in January 2022 carrying the CSG-2 cargo mission.
