What: Falcon 9 rocket launch from Vandenberg Space Force Base in Santa Barbara County 

When: Between 3:20 a.m. and 4:17 a.m. Monday, according to SpaceX. If needed, the team has backup opportunities during another 57-minute window at the same time Tuesday. 

Where: Space Launch Complex-4 on South Base.

Landing: The first-stage booster, making its 12th flight, will return to land on the Of Course I Still Love You droneship positioned in the Pacific Ocean. 

Why: Deliver 119 payloads into orbit for the Transporter-16 mission. 

Cargo on this flight includes cubesats, microsats, hosted payloads, a reentry vehicle, and orbital transfer vehicles carrying eight of those payloads to be deployed at a later time.

Watch: A live webcast of the mission is scheduled to begin about 15 minutes before liftoff at spacex.com/launches and on X @SpaceX.

To watch the liftoff in person, the Lompoc Valley has multiple locations offering views of the launch pad. Those include the peak of Harris Grade Road, west of Lompoc’s city limits and around Vandenberg Village, including near the intersection of Moonglow and Stardust roads. 

Vandenberg launches close to sunset or sunrise can be especially picturesque. If skies are clear, the rocket’s departure might be visible from elsewhere around California and, under certain conditions, other Western states.

Upcoming launches: SpaceX plans to conduct additional Falcon 9 rocket launches on April 2 and April 6 from Vandenberg to deliver Starlink satellites into orbit.
