Launch Hub
Every upcoming launch, with a live countdown, the rocket, the pad, and a push alert the moment it goes live.
What it does
Everything above you, in one app.
Stellara reads your sky in real time — where you are, what is overhead, and what is about to launch, fly past, or light up the magnetosphere.
3D sky map
The real sky above you right now — stars by spectral class, planets at true positions, all 88 constellations, satellites overhead.
AR sky mode
Hold your phone up and the sky labels itself. Works in daylight, works offline.
NEO & space weather
Close approaches sized against things you know, impact-risk ratings from JPL, and the Kp index when the aurora is out.
The Codex
Rotatable 3D planets, thousands of exoplanets, and everyone who is in space right now.
Daily Cosmos
NASA's Astronomy Picture of the Day, plus a searchable library of NASA photos and video.
Powered by
Real data, from the people who collect it.
Stellara does not invent anything. Every number in it comes from a public source, and every one of them is credited.
Legal
The boring, important part.
Written to be read, not to be skipped.
