SpaceX delayed its planned Monday launch of a Falcon 9 rocket from Cape Canaveral Space Force Station, pushing the Starlink 10-19 mission to Tuesday, Aug. 11. The mission was scrubbed hours before its 12:20 p.m. EDT (1620 UTC) liftoff window at Space Launch Complex 40. This is the 72nd Starlink flight this year and would mark the 93rd Falcon 9 launch in 2026 if successful. The rocket is set to lift off at 10:26 a.m. EDT (1426 UTC) Tuesday on a northeasterly trajectory.
The 45th Weather Squadron reported an 85% chance of favorable conditions at the start of the Tuesday window, dropping to 75% by the end. Weather officers noted the Atlantic ridge axis would shift southward, bringing light south-southwesterly winds but leaving the Cumulus Cloud Rule as the primary concern. The rule prohibits launches if cumulus clouds form near the launch pad, increasing the risk of violation later in the window.
The mission will use Falcon 9 booster B1085, which has flown 17 times previously, including NASA’s Crew-9 mission, the GPS III-7 satellite launch, and the Fram2 mission. The booster will attempt its 18th flight and is scheduled to land on the droneship A Shortfall of Gravitas in the Atlantic Ocean off South Carolina about 8.5 minutes after liftoff.
SpaceX has conducted 93 Falcon 9 launches in 2026 as of this mission, with the Starlink 10-19 flight carrying the latest version of its broadband internet satellites. The company has not yet confirmed whether Monday’s scrub will affect future launch schedules, but officials said teams are reviewing data to ensure the rocket’s systems are ready for Tuesday’s attempt.
