The mission

Falcon 9 is set to launch OneWeb 21 for SpaceX from Space Launch Complex 4E in Vandenberg SFB, CA, USA, Mon, Nov 30 · 12:00 AM UTC, a time still to be confirmed. Target orbit: Polar. Mission type: Communications. The first stage is booster Unknown F9. It is SpaceX's 753rd launch.

A batch of 32 satellites for the OneWeb satellite constellation, which is intended to provide global Internet broadband service for individual consumers. The constellation is planned to have around 648 microsatellites (of which 60 are spares), around 150 kg each, operating in Ku band from low Earth orbit.

Mission description from Launch Library 2.

See it on the radar: the countdown, the flight path and where to look from your ZIP code.

Can I see it?

Set your ZIP code on the radar to see how far you are from the pad.

Liftoff is in daylight at the pad. In daylight a rocket shows only as a white exhaust trail, which people usually see from within about 124 mi (200 km).

It should head south from the pad. We guess the heading from the target orbit, so the real path can differ.

Whether you can see it depends on where you are, the weather and the exact time. Open it on Astro Radar with your ZIP code for a modeled estimate of where to look, worked out for every second of the flight. It is an estimate, not a promise.

Watch it with friends

Send OneWeb 21 · Falcon 9 to a group chat on Astro, or make it a plan: Astro opens a new plan called Watch OneWeb 21 · Falcon 9 with the day and time filled in, for a group or a friend. The time is still to be confirmed, so check it again before the day.

Astro asks you to sign in first, then brings you back to this launch. It gets only the launch's name, time and link, and only when you press the button. Astro is for people 18 and older.

From Launch Library 2, as of Nov 13, 6:26 AM UTC. Times and status can change; the radar has the latest.
