SpaceX is closing out the weekend with a mid-morning Falcon 9 rocket launch from Vandenberg Space Force Base in California.
The Starlink 11-15 mission will add another 28 broadband internet satellites to its massive low Earth orbit constellation. This will be SpaceX’s 115th launch of Starlink satellites so far in 2025.
Liftoff from Space Launch Complex 4 East is scheduled for 9:58 a.m. PST (12:58 p.m. EST / 1758 UTC). The rocket will fly on a south-easterly trajectory upon leaving the launch pad.
Spaceflight Now will have live coverage beginning about 30 minutes prior to liftoff.
SpaceX will launch the mission using the Falcon 9 booster with the tail number 1088. This will its 12th flight following the launches of NASA’s SPHEREx, Transporter-12 and two missions for the National Reconnaissance Office (NROL-57 and NROL-126).
About 8.5 minutes after liftoff, B1088 will perform an autonomous landing on the drone ship, ‘Of Course I Still Love You.’ If successful, this will be the 168th booster landing on this vessel and the 545th booster landing to date for SpaceX.
SpaceX has another launch scheduled for later in the day on Sunday from NASA’s Kennedy Space Center. That mission will feature the 3,000th Starlink satellite launched in 2025.
