Space Station Passes2.1.1 - App Store

Know when to look up-and where to look.

Space Station Passes helps you spot the International Space Station, Tiangong, and other satellites from your chosen location. Plan your next observation with pass forecasts, interactive sky charts, and reminders.

. Find your next visible pass: See upcoming passes, their timing, and how high each satellite will appear above the horizon.

. Follow the path across the sky: Explore interactive charts with stars, constellations, the Milky Way, and the Moon.

. Know the key moments: Check when a satellite rises, reaches its highest visible point, and disappears from view.

. Set a reminder: Schedule an alert for the pass you want to watch.

. Explore beyond the space stations: Browse thousands of satellites, including bright satellites and recent launches.

Explore the live planetarium in the Sky now tab. Search passing satellites, filter by distance or illumination, follow their paths, and report the brightness you observe.
