During pre-launch checks on Wednesday the launch was scrapped due to un-favorable upper-level winds. The back-up launch moved to 10:30pm ET Thursday. SpaceX launches 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.
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.
About 1 hour and 3 minutes after the launch, the entire stack of 60 satellites floated away from the Falcon 9’s second stage. Slowly—very slowly, it appeared—the 60 satellites began to drift apart. The SpaceX webcast ended without saying whether this deployment went as anticipated, and it probably will take some time for the Air Force to begin identifying and tracking the individual satellites.ArsTechnica
