Vandenberg Space Force Base in California is preparing for a Falcon 9 launch of the classified USSF-627 mission on Monday, Nov. 9. The launch window runs from 7:03 p.m. to 11:03 p.m. Pacific Time, giving the team several hours to achieve a successful liftoff.
Backup window and live webcast
If conditions prevent a Monday launch, a backup window has been scheduled for Tuesday, Nov. 10, beginning at 6:49 p.m. Pacific Time. SpaceX will provide a live webcast of the event, starting about ten minutes before liftoff. Viewers can watch the stream on the station’s website or via SpaceX’s X (formerly Twitter) account.
Booster recovery plan
Following first‑stage separation, the booster assigned to USSF-627 will attempt a controlled return to Earth. The vehicle is slated to land on the autonomous droneship Of Course I Still Love You, which will be positioned in the Pacific Ocean to catch the returning stage.
Launch history of the booster
This will be the seventh flight for the Falcon 9 booster used on the mission. Its prior assignments include the classified payloads NROL‑179, SDA‑T1TL‑E, SDA‑T1TL‑A, as well as three Starlink satellite deployments.
Potential sonic booms
Residents in the surrounding region may hear one or more sonic booms as the vehicle passes the sound barrier. The distance the sound travels will depend on atmospheric conditions at launch time, so the exact impact on local communities cannot be predicted in advance.
Local significance
Vandenberg Space Force Base has long been a hub for national security and commercial space missions. The USSF-627 launch underscores the base’s ongoing role in supporting both defense‑related payloads and the broader commercial space industry. The event also brings attention to the region’s contribution to America’s space capabilities, a point of pride for local families and businesses.
What to watch for
Anyone interested in the launch can tune in to the live webcast for real‑time updates. The mission’s classified nature means specific payload details will not be released, but the successful recovery of the booster will be a visible indicator of the launch’s outcome.
As the launch window approaches, officials will continue to monitor weather patterns and safety considerations. Updates will be posted on the station’s website and through SpaceX’s social channels.
