SpaceX cancels satellite launch just seconds before takeoff

On July 21, 2025, in Florida at Cape Canaveral Space Station, SpaceX was set to launch two O3b mPOWER satellites for Luxembourg-based SES. The Falcon 9 rocket's countdown clock reached 11 seconds before a launch director called for a halt, resulting in the scrub of the launch. The exact reason for the cancellation was not disclosed, though previous weather forecasts indicated a 50% chance of favorable conditions. This launch was vital for SES, as it aligns with their mission to provide better connectivity to underserved populations globally. The next possible launch window is the following day with even lower chances of favorable weather at 25%. SpaceX aims to continue deploying its next-generation satellite network, which had previously seen the successful launch of eight satellites into medium Earth orbit. The O3b mPOWER satellites are intended to support telecommunications, providing much-needed connections to 'the other three billion,' a reference to those without reliable access to communication systems. Historically, the company has had a successful track record with its Falcon 9, demonstrated by its previous missions involving essential satellite deployments and NASA launches. The missions contribute to advancements in satellite technology and efforts to enhance global communications, which has become increasingly critical in the digital age.
