Mission brief

What is happening

SpaceX is launching Starlink Group 15-25 on a Falcon 9 Block 5 from Space Launch Complex 4E at Vandenberg SFB, CA, USA. It is a communications mission heading to Low Earth Orbit. The first stage, B1082, is flying for the 25th time, and will attempt a droneship at sea.

Why it matters

Constellation launches fly in batches and repeat often, which is what makes the cadence rather than any single flight the thing worth watching.

The published time looks firm.

Why does RocketRune rate it this way?
  • Launch time published to the minute.
  • The provider has declared the mission go for launch.
  • An official launch window has been published.
  • The launch time last changed 1 hour ago.

This is a RocketRune assessment of how firm the published schedule is, not a prediction of launch success. It is calculated from the date precision and status published by the launch provider, plus the schedule changes RocketRune has recorded for this mission.
