SpaceX successfully launches long-delayed Starlink L-17 mission March 3, 2021 SpaceX launched the Starlink v1.0 L17 mission with a new batch of Starlink satellites from historic LC-39A at the Kennedy Space Center aboard a flight proven Falcon 9 booster Thursday morning. The previous launch attempt on Sunday, February 28 ended in a scrub at T-1 minute 24 seconds. Falcon 9 launched at 03:24 EST (08:24 UTC) with the booster successfully landing on the drone ship Of Course I Still Love You. The 20th Starlink mission to date, this launch lofted another 60 satellites for SpaceX’s ever-growing Starlink satellite internet constellation. Due to technical, weather, and droneship-related delays, Starlink v1.0 L17 found itself launching after the L18 and L19 missions. This was the first time that a Starlink mission was launched “out-of-order,” but it was far from a first for spaceflight in general; the Space Shuttle program was frequently filled with seemingly confusing mission numbers.
