SpaceX is targeting Thursday, May 23 for the launch of 60 Starlink satellites from Space Launch Complex 40 (SLC-40) at Cape Canaveral Air Force Station, Florida. SpaceX’s Starlink is a next-generation satellite network capable of connecting the globe, especially reaching those who are not yet connected, with reliable and affordable broadband internet services.
The launch window opens at 10:30 p.m. EDT on May 23, or 2:30 UTC on May 24, and closes at 12:00 a.m. on May 24, or 4:00 UTC. A backup launch window opens on Friday, May 24 at 10:30 p.m. EDT, or 2:30 UTC on May 25, and closes at 12:00 a.m. on May 25, or 4:00 UTC. Falcon 9’s first stage for this mission previously supported the Telstar 18 VANTAGE mission in September 2018 and the Iridium-8 mission in January 2019. Following stage separation, SpaceX will attempt to land Falcon 9’s first stage on the “Of Course I Still Love You” droneship, which will be stationed in the Atlantic Ocean. Approximately one hour and two minutes after liftoff, the Starlink satellites will begin deployment at an altitude of 440km. They will then use onboard propulsion to reach an operational altitude of 550km.
