VANDENBERG SPACE FORCE BASE, California — SpaceX launched a Falcon 9 rocket early Tuesday, sending 81 payloads to orbit on its Transporter-17 rideshare mission from Vandenberg Space Force Base during a 95-minute window that opened at 3:10 a.m. EDT. The mission carried a mix of cubesats, microsats, hosted payloads, and several orbital transfer vehicles, which will later release eight additional payloads into their own orbits. The largest spacecraft on board was CAS500-4, a roughly 500-kilogram South Korean Earth-observation satellite that will become the fourth member of a planned five-satellite CAS500 constellation in low Earth orbit. The CAS500-4 satellite is designed to support the South Korean government’s efforts to monitor crops and forests, adding to the country’s capacity for environmental and resource management from space. About 8.5 minutes after liftoff, the Falcon 9 first stage completed its 11th flight by landing on the droneship "Of Course I Still Love You" in the Pacific Ocean. SpaceX’s Transporter rideshare program has now flown 20 missions and delivered more than 1,800 payloads to orbit. The series began with Transporter-1 in January 2021, which set a record for the most satellites launched on a single rocket with 143 payloads.
