SpaceX called off its Starlink 6-61 mission at 11:08 a.m. EDT on Thursday, 30 seconds before the scheduled 11:38 a.m. launch from Space Launch Complex 40 at Cape Canaveral Space Force Station. The abort halted the company's 75th Starlink launch of the year, which would have deployed 29 broadband satellites to low Earth orbit. No reason for the scrub was given by SpaceX during its final countdown broadcast. The mission was the second Starlink launch attempt at the site this month after a Sept. 18 delay due to weather. Weather concerns remain for a potential Friday attempt. The 45th Weather Squadron forecasts an 80% chance of favorable conditions at the start of the 10:30 a.m. to 1:30 p.m. EDT launch window on Friday, but the probability drops to 40% as the window progresses. Launch weather officers noted isolated showers and storms along the sea breeze could pose risks early in the window, though models show storms may track eastward later. SpaceX aims to reuse Falcon 9 booster B1078 for the mission, which will make its 30th flight if successful. The booster, which previously launched GPS satellites and Starlink missions, would become the sixth Falcon 9 to reach 30 flights. The rocket's first stage is expected to land on the droneship A Shortfall of Gravitas in the Atlantic Ocean about 8.5 minutes after liftoff. SpaceX has not announced a new launch date for the mission, which would be the 10th Starlink mission of 2024 from Cape Canaveral. The company typically attempts multiple Starlink launches monthly from the East Coast, with delays often tied to weather or technical checks. The scrub follows a busy week for the spaceport, which also hosted a U.S. Air Force test launch earlier this month.
