Satellite reentry alerts — when something's about to fall
A free push or email when a satellite or rocket body is predicted to reenter — then track the descent live.
Yes — you can get notified before a satellite reentry. Cosmik watches for objects whose orbits are decaying and sends you a free alert when one is predicted to fall back to Earth, with the estimated window and a link to follow it live on the 3D map. Set up reentry alerts →
How reentry predictions work
Every satellite feels a faint atmospheric drag. As an object's altitude drops, each orbit gets a little lower and a little faster, until it dips deep enough into the atmosphere to burn up. Cosmik reads the same live orbital data behind the 3D map, flags the objects low enough to reenter soon, and propagates their shrinking orbits — so you see the descent coming instead of finding out after the fireball. Read what happens when satellites fall for the full story on why most burn up and what (rarely) survives.
What the alerts tell you
- A heads-up before reentry — a push or email when an object is predicted to fall, no account needed.
- The current predicted window — refined as fresh tracking data arrives, because reentry timing shifts.
- A live link to track it — watch the object and its decaying orbit move on the 3D map in real time.
- Context — what the object is, and whether anything is likely to reach the ground (almost never).
Track the reentry live
See what's coming down right now on the satellite reentries hub — a live list of the lowest active objects still in orbit, each with its own reentry page. When an alert lands, open the live satellite tracker to watch the object descend, or browse the full satellite database to see everything else in orbit. Want the same treatment for things going up?

FAQ
Can I get notifications for satellite reentry events?
Yes. Cosmik sends a free push or email when a tracked satellite or rocket body is predicted to reenter Earth's atmosphere, with the estimated window and a link to follow it live on the 3D map. Enable alerts once — no account needed — and you'll be told before the next reentry.
How do you track a satellite's reentry in real time?
As an object's orbit decays, its altitude drops on every pass. Cosmik flags these reentry candidates from live orbital data and shows each one moving on the map with its shrinking orbit and predicted ground track, so you can watch the descent unfold and see roughly where and when it may come down.
Are satellite reentry alerts free?
Yes, completely free — browser push or email, your choice, no account required. Cosmik updates the prediction as fresh tracking data arrives, so the window you get is the latest one.
How accurate are reentry predictions?
Reentry timing is genuinely hard to pin down: atmospheric drag varies with solar activity, so even hours before reentry the window can span several orbits. Cosmik gives the current best estimate and refines it as new data comes in — useful for knowing something is about to fall, less so for pinpointing the exact minute or place.
Will a reentering satellite hit the ground?
Almost always, no. The overwhelming majority of satellites and rocket bodies burn up completely in the atmosphere, sometimes producing a bright, slow fireball. Only large objects leave fragments that reach the surface, and the odds of debris reaching any given person are vanishingly small. See what happens when satellites fall for the full picture.
