SpaceX launched an uncrewed Cargo Dragon to the International Space Station on Monday, April 21, with a resupply mission that has increased importance following a transportation mishap earlier this year. The mission, dubbed Commercial Resupply Services 32 (CRS-32), carries approximately 6,700 pounds of science and supplies to the station.
The Dragon spacecraft separated from the upper stage of the Falcon 9 rocket about 9.5 minutes after launch and is expected to dock with the ISS forward port of the Harmony module on Tuesday, April 22, around 8:20 a.m. EDT (1220 UTC). The rendezvous will be overseen by NASA astronauts Jonny Kim and Takuya Onishi.
The mission includes a suite of payloads for the Department of Defense’s Space Test Program, which was not previously disclosed. This includes the STP-H10 payload suite, weighing 3,000 kg, as well as other scientific experiments such as those from Rensselaer Polytechnic Institute and the ISS National Laboratory.
The Cargo Dragon carries over 4,780 pounds of pressurized cargo and 1,653 pounds of unpressurized payloads. The mission includes more than 30 new experiments, including studies on protein fluid flow, aerosol monitors, and space radiation on telomeres.
SpaceX used the Falcon 9 first stage booster 1092 for the CRS-32 mission, which marked its third flight following previous Starlink launches. The booster successfully landed at Cape Canaveral Space Force Station after landing Zone 1 (LZ-1).
