What to expect from Starlink Group 15-21

Starlink Group 15-21 is planned for a Falcon 9 Block 5, flown by SpaceX from Space Launch Complex 4E, Vandenberg SFB, CA, USA.

Starlink is SpaceX’s own satellite internet constellation, so a Starlink launch is the provider flying a batch of its own satellites rather than a customer payload.

Target orbit: Low Earth Orbit. Low Earth Orbit (LEO) is the region up to roughly 2,000 km above Earth, where crewed spacecraft and many satellites operate.
