Falcon 9 Block 5 first-stage booster B1061 flew 23 missions between November 2020 and October 2024. It debuted on Crew-1 and completed its final, intentionally expendable flight launching ESA’s Hera planetary-defence mission to interplanetary transfer orbit from SLC-40 on 7 October 2024. SpaceX’s mission record identifies Hera as the booster’s 23rd and final launch; contemporary launch reporting identifies the stage as B1061.
