Cosmik

The live map of the cosmos

Cosmik tracks the ISS, Starlink and 20,000+ satellites in real time 3D, straight from official orbital data — plus every rocket launch with live countdowns and webcasts, and the planets, comets and deep-space probes of the solar system. It runs in your browser: free, no login, no app to install.

Never miss a thing overhead

Follow any satellite or launch and get a free push or email alert minutes before it matters: the ISS crossing your sky, a fresh Starlink train, the next SpaceX launch or a Starship flight from Starbase. Check ISS pass times for 150 cities in local time.
