Launch detail
SpaceX • Falcon 9 Block 5 • Space Launch Complex 4E (CA)
A batch of 27 satellites for the Starlink mega-constellation - SpaceX's project for space-based Internet communication system.
Planned targets around liftoff.
SpaceX’s Falcon 9 is targeting the launch of 27 Starlink satellites to low-Earth orbit from Space Launch Complex 4 East (SLC-4E) at Vandenberg Space Force Base in California.
A live webcast of this mission will begin about 10 minutes prior to liftoff, which you can watch here and on X @SpaceX .
This will be the 36th flight for the first stage booster supporting this mission, which previously launched Sentinel-6 Michael Freilich, DART, Transporter-7, Iridium OneWeb, SDA-0B, NROL-113, NROL-167, NROL-149, NAOS, and 26 Starlink missions. Following stage separation, the first stage will land on the Of Course I Still Love You droneship, which will be stationed in the Pacific Ocean.
There is the possibility that residents of Santa Barbara, San Luis Obispo, and Ventura counties may hear one or more sonic booms during the launch, but what residents experience will depend on weather and other conditions.

Falcon 9 is a two-stage rocket designed and manufactured by SpaceX for the reliable and safe transport of satellites and the Dragon spacecraft into orbit. The Block 5 variant is the fifth major interval aimed at improving upon the ability for rapid reusability.
All Times Approximate
Space Exploration Technologies Corp., known as SpaceX, is an American aerospace manufacturer and space transport services company headquartered in Hawthorne, California. It was founded in 2002 by entrepreneur Elon Musk with the goal of reducing space transportation costs and enabling the colonization of Mars. SpaceX operates from many pads, on the East Coast of the US they operate from SLC-40 at Cape Canaveral Space Force Station and historic LC-39A at Kennedy Space Center. They also operate from SLC-4E at Vandenberg Space Force Base, California, usually for polar launches. Another launch site is being developed at Boca Chica, Texas.
Payload and object details are usually published 1–2 days after launch.

Launch-stage and landing context surfaced from LL2 when it exists.
The Falcon 9 first stage B1063 will land on ASDS OCISLY after its 36th flight.
A launch-area reference planning index. Use your location for a viewpoint-specific result.
A broad, sunlit jellyfish-style plume is unlikely at the launch area under the current model. The rocket may still be visible as a point.
This is a planning index, not a percent chance. Higher means the modeled viewing setup is stronger.
If needed, your browser asks permission only after you choose this. The launch-area result is not a forecast for your viewpoint.
This score uses a modeled ascent corridor rather than an exact mission path. The overall viewing setup remains useful; direction and timing are approximate.
The setup is weak right now because multiple parts of the visibility chain are underperforming.
This outlook evaluates whether a broad, sunlit ascent plume could stand out. It does not yet predict whether a specific vehicle will produce one, and an unfavorable plume outlook does not mean the rocket itself will be invisible.
