SpaceX launched 27 Starlink satellites from Vandenberg Space Force Base in California on 23 October. Falcon 9 lifted off from Space Launch Complex 4 East at 3:48pm Pacific time, according to the company's mission account.

The first-stage booster was flying for the 36th time. After separating from the upper stage, it returned to land on the droneship Of Course I Still Love You in the Pacific Ocean.

The reused stage has carried several kinds of mission

SpaceX’s official mission description lists the booster’s earlier work, including NASA’s DART mission, Sentinel-6 Michael Freilich, Transporter-7 and several national-security and commercial launches. This was the booster’s 27th Starlink mission.

A booster flight count measures reuse of that first stage. The upper stage continues the orbital mission after separation, while the returning stage handles the descent and landing sequence.

Vandenberg recorded its 71st launch of the year

The US Space Force’s released photographs and captions identify the payload as 27 Starlink satellites and describe the mission as Vandenberg’s 71st supported launch of 2026. Space Launch Delta 30 supplied the range capabilities for the flight.

The three counts describe the payload, booster reuse and launch site: 27 satellites, the first stage’s 36th flight and Vandenberg’s 71st launch of 2026.

SpaceX’s public mission data identifies Group 15-16 as another Vandenberg Starlink flight. The current timing record targets 27 October; the precise launch time remains provisional.

Launch dates and times can move as the vehicle, weather and range are cleared.
