Summary
STP-2 launched on a SpaceX Falcon Heavy from Launch Complex 39A, Kennedy Space Center, FL, USA on June 25, 2019. It was SpaceX's 81st launch, 8th this year and humanity's 5,860th orbital launch attempt. It was the 3rd Falcon Heavy flight and the 2nd this year. Booster B1057 flew for the 1st time and its landing at Of Course I Still Love You failed. Booster B1052 flew for the 2nd time and landed at Landing Zone 1. Booster B1053 flew for the 2nd time and landed at Landing Zone 2. The payload was bound for low Earth orbit (LEO). Prox-1, one of 27 catalogued objects, reached a 718 × 732 km orbit inclined 24.0°. 27 objects from this launch are catalogued, 25 of them payloads.
