A Falcon 9 rocket slated to deploy 27 Starlink satellites from Vandenberg Air Force Base was scrubbed due to a technical issue, with the mission now pushed to the following day.

A technical glitch forced SpaceX to postpone its Falcon 9 launch of 27 Starlink satellites from Vandenberg Air Force Base, pushing the mission to the following day.

What caused the scrub?

SpaceX officials reported a “minor anomaly” detected during the final pre‑launch checklist. The issue, related to a telemetry sensor on the vehicle’s first‑stage propulsion system, prompted the range safety team to hold the countdown.

Impact on the launch schedule

The launch, originally slated for 2026‑10‑20, has been rescheduled for 2026‑10‑21 at the same launch window. The delay does not affect the broader Starlink deployment timeline, as the constellation’s rollout continues from other sites.

Customers awaiting the new batch of broadband‑enabled satellites will see the same service improvements, with no change to the planned orbital parameters.

Technical details of the Falcon 9 mission

The Falcon 9 booster will deliver the 27 satellites into a low‑Earth orbit of approximately 540 km altitude. Each Starlink satellite weighs about 260 kg and carries advanced phased‑array antennas for high‑speed internet connectivity.

  • 27 Starlink satellites
  • Falcon 9 first‑stage booster
  • Launch from Vandenberg SFB, California
  • Target orbit: 540 km circular
