SpaceX Starlink 15-16 Set for Record 72nd California Launch of 2026 From Vandenberg

SpaceX is scheduled to launch 27 Starlink satellites from Vandenberg Space Force Base in California late on Monday, October 26, in a window opening at 9:45 p.m. Pacific Time and closing at 1:45 a.m. Pacific on Tuesday, October 27. If it flies as planned, the mission — Starlink 15-16 — will be the 72nd launch of 2026 from California, surpassing the state's total for all of 2025 and setting a new annual record. The flight had not yet lifted off at the time of writing, and spaceflight schedules can slip; this article reports the scheduled mission, not a completed launch.

The Mission

Starlink 15-16 will use a Falcon 9 rocket, the 230-foot two-stage reusable vehicle that is the most active rocket in the world, launching from Space Launch Complex 4-East (SLC-4E) at Vandenberg. The payload is 27 Starlink V2 Mini satellites bound for low-Earth orbit, where they will join SpaceX's broadband constellation. The mission's first-stage booster, B1082, will be making its 26th flight, and SpaceX plans to recover it on the droneship Of Course I Still Love You in the Pacific Ocean. Local officials warned residents the launch could produce sonic booms that travel depending on weather, and SpaceX planned a live webcast beginning about ten minutes before liftoff on its X channel.

The record is the story, not just the satellite count. An October 23 mission tied California's 2025 total, and this flight would move past it — the 72nd California launch of 2026 against 71 for all of 2025. Vandenberg itself has moved toward a much higher yearly cadence, with plans discussed for as many as 100 launches per year from the site. Two launches from one pad inside three days is the operational point: a second mission, Starlink 15-18, is scheduled from the same pad on Thursday, October 29 at 9:02 p.m. Pacific, a gap of about 71 hours if both fly at their listed times.

Why the Cadence Matters

Reusable boosters are what make this pace possible. A booster on its 26th flight is not an experiment — it is inventory, refurbished and reflown on a schedule closer to aviation than to traditional rocketry. That reuse, plus a satellite production line that can feed two launches from one pad in three days, is why Starlink can keep growing its constellation while other providers measure launches in single digits per year. The record also reflects a shift in where American launches happen: California, once a secondary launch state behind Florida, now sets its own annual records through Vandenberg's polar and sun-synchronous orbit traffic, which suits Earth-observation and broadband constellations.

Background: How Vandenberg Became a Record-Setting Pad

Vandenberg Space Force Base, on California's central coast, launches southward over the Pacific into polar and sun-synchronous orbits — the paths favoured by Earth-observation satellites and broadband constellations like Starlink. For years it was a quieter cousin of Florida's Cape Canaveral, which handles most eastward launches to equatorial orbits. SpaceX's Starlink deployment changed that arithmetic: a constellation that needs thousands of satellites, launched in batches of dozens, rewards any pad that can turn around quickly, and Vandenberg's coastal range, clear southern corridors and growing ground support have let it do exactly that.

The cadence numbers tell the story. California's 71 launches in all of 2025 were already a state record; reaching 72 before November, with another mission scheduled three days later from the same pad, shows a launch industry that has moved from counting launches per year to counting them per week. Reusable boosters are the enabler — B1082's 26th flight would once have been unthinkable for an orbital rocket — and the satellite production line is the other half: a pad can only launch as fast as satellites arrive, and Starlink's factory pace is what keeps the pad busy.

What to Watch

First, whether Starlink 15-16 flies inside its window or slips to the backup opportunity the following day — delays in spaceflight are common, and a scrub would not change the record math, only its date. Second, whether the booster recovery succeeds on its 26th flight, extending one of the most-flown boosters in service. Third, whether Starlink 15-18 follows on Thursday as scheduled, confirming the three-day pad turnaround. Viewers in California and Arizona were advised to check for updates before heading out, since launch times and sonic-boom audibility depend on weather and range conditions.
