Mission brief

What is happening

SpaceX is launching Starlink Group 15-21 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, B1103, is flying for the 7th 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.
