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 the dark at the pad. You would see the engine flame, which fades quickly with distance: people usually see it from within about 249 mi (400 km).

It should head northeast 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 Amazon Leo (LE-04) · Ariane 64 to a group chat on Astro, or make it a plan: Astro opens a new plan called Watch Amazon Leo (LE-04) · Ariane 64 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.
