With the rideshare sequence now begun, all 45 payloads are expected to be released over the coming hours. We will update further once full deployment is complete.

📌 UPDATE — May 3, 2026

SpaceX successfully launched the CAS500-2 mission at 11:59 p.m. PT, with Falcon 9 lifting off from SLC-4E at Vandenberg as planned. Approximately eight minutes after liftoff, the first stage executed a precise return and touched down on Landing Zone 4, marking another successful booster recovery for the reusable rocket program.

SpaceX has raised Falcon 9 to vertical at Space Launch Complex 4E (SLC-4E) at Vandenberg Space Force Base in California, signaling final preparations for tonight's CAS500-2 mission. The 37-minute launch window opens at 11:59 p.m. PT (6:59 a.m. UTC on May 3), with 45 payloads packed aboard for what amounts to a busy rideshare flight.

The headline payload is CAS500-2, an Earth-observation satellite developed by the Korean Aerospace Research Institute (KARI). Designed to capture imagery in both panchromatic and multispectral modes, it joins a crowded manifest of 44 additional rideshare passengers. SpaceX had previously listed 46 payloads for this mission before updating the count to 45.

Booster B1071 is doing the heavy lifting — and it's no rookie. This marks the veteran first stage's 33rd flight. After separation, B1071 is expected to return to Landing Zone 4 (LZ-4) at Vandenberg rather than a drone ship, a relatively short trip back to solid ground. A live webcast will begin approximately 15 minutes before liftoff via SpaceX's official channels.

A backup launch opportunity is available on May 3 if tonight's window doesn't work out. Weather and range conditions at Vandenberg will be the deciding factors. For anyone tracking the West Coast night sky, a successful launch should produce a visible plume over Southern California shortly after midnight.
