SpaceX Falcon 9 to Launch Classified USSF-153 Mission Thursday Morning

A Falcon 9 rocket carrying a classified U.S. Space Force payload is scheduled to lift off from Vandenberg between 8:37 a.m. and 11:37 a.m. Thursday.

A SpaceX Falcon 9 rocket carrying the USSF-153 mission is scheduled to launch from Space Launch Complex 4E at Vandenberg Space Force Base on Thursday, September 10, with a three-hour window opening at 8:37 a.m. Pacific Time. If needed, a backup launch opportunity is set for Friday starting at 8:23 a.m.

The payload for this U.S. Space Force launch appears to be classified. A live webcast will begin about ten minutes before liftoff and can be viewed on SpaceX's platforms.

Booster Recovery and Sonic Booms

After first-stage separation, the booster will return to land on the Of Course I Still Love You droneship in the Pacific Ocean. This will be the 27th flight for this particular Falcon 9 booster, which has previously launched Crew-7, CRS-29, PACE, multiple Transporter missions, and 16 Starlink flights.

Residents across the region may hear one or more sonic booms during the launch, though how far the sound travels depends on weather and atmospheric conditions at launch time. For more space news from Vandenberg, visit /news.
