At a Glance

B1097 is an active Falcon 9 Block 5 booster in SpaceX's operational fleet, serial number 1097 in the company's production sequence. Since its debut on September 3, 2025, this first stage has completed eight orbital missions and stuck every single landing, a perfect record that reflects the maturation of reusable rocket technology along California's Central Coast and beyond.

Of those eight flights, two have lifted off from Vandenberg Space Force Base's Space Launch Complex 4E, both carrying Starlink satellites into polar orbit. The booster remains in active rotation as of April 2026, turning around between flights in a matter of weeks and demonstrating the kind of operational tempo that has become routine for SpaceX's most flight-proven hardware.

The Career of B1097

B1097 entered service in the fall of 2025, a period when SpaceX was operating multiple boosters across both coasts to maintain its Starlink constellation build-out and commercial launch manifest. The booster's first Vandenberg appearance came on March 8, 2026, when it lifted Starlink Group 17-18 into a sun-synchronous orbit from SLC-4E. That mission marked flight number seven for the booster, meaning it had already proven itself six times from other pads before arriving on the Central Coast.

Six weeks later, on April 19, 2026, B1097 returned to the same pad for Starlink Group 17-22, its eighth flight overall and second Vandenberg mission. The quick turnaround between missions reflects SpaceX's increasing confidence in the Block 5 design, which was built from the outset to fly ten times with minimal refurbishment and up to one hundred times with periodic overhauls. B1097 is nowhere near those upper limits yet, but its record shows the kind of steady, predictable reuse that has become the backbone of the company's launch cadence.

The booster's career arc is typical of the current Falcon 9 fleet: a mix of missions from multiple pads, supporting both internal Starlink builds and external customers, with each flight adding another data point to SpaceX's growing library of booster performance metrics. For residents of Lompoc, Vandenberg Village, and the communities that line Highway 1 north of Point Sal, B1097's two visits have meant evening light shows and the familiar rumble of nine Merlin engines climbing out over the Pacific.

Vandenberg Missions

On March 8, 2026, B1097 launched Starlink Group 17-18 from SLC-4E, its seventh overall flight and first at Vandenberg. The mission placed another batch of internet satellites into a high-inclination orbit, a trajectory that Vandenberg is uniquely suited to support thanks to its westward launch corridors over open ocean. Five weeks later, on April 19, 2026, the same booster returned to SLC-4E for Starlink Group 17-22, its eighth flight. Both missions ended in successful booster recoveries, continuing B1097's unblemished landing streak and adding to the growing tally of reused hardware flying from the Central Coast.

Landings and Recovery

Most Falcon 9 missions from Vandenberg send their first stages downrange to land on the autonomous droneship Of Course I Still Love You, stationed several hundred miles off the California coast in the Pacific. These ocean landings are the norm for high-energy polar orbits, where the booster's trajectory carries it too far west to turn around for a return to the launch site. B1097's Vandenberg flights likely followed this pattern, with the booster touching down on the droneship's deck roughly eight minutes after liftoff, then riding the platform back to port for inspection and refurbishment.

Return-to-launch-site landings do happen at Vandenberg, when mission performance allows. Those flights bring the booster back to Landing Zone 4, the concrete pad adjacent to SLC-4E, producing a double sonic boom that rattles windows in Lompoc and can be heard as far north as Santa Maria. The sound is a favorite among local space enthusiasts, a visceral reminder that the rocket you watched climb into the sky is now descending, engines blazing, to land just a few miles from where it started. B1097 has not yet performed this maneuver at Vandenberg, but its active status means the possibility remains open on future flights.

Still in the Game

B1097 remains an active booster in SpaceX's fleet, its eight flights and eight landings placing it squarely in the middle of the reuse spectrum. Some boosters in the current rotation have flown more than twenty times; others are still on their first or second outings. B1097 sits in the productive middle, turning around every few weeks, supporting the infrastructure that keeps the Starlink network growing and the launch manifest moving. Whether its next flight originates from Vandenberg or one of SpaceX's other pads, the booster's track record suggests it will continue contributing to the Central Coast's role as a gateway to polar orbit for years to come.
