A provenance-first, API-first satellite encyclopedia covering 10,000+ active objects — the open successor to the UCS Satellite Database. Search, query, and build on the most complete public record of what's in space.
No spam. One email when we launch.
What's coming
Every active object in orbit with normalized metadata — name, operator, country, orbit class, launch date, and status — all in one place.
Every data point traces back to its source. No black boxes. See exactly where the information came from and how confident we are in it.
A clean, stable, read-only API with source attribution headers, rate limiting, and consistent IDs. Built for developers who actually want to use it.
No paywalls on the core data. Methodology, sources, and error rates are public. Report corrections directly via GitHub.
Live orbital elements from CelesTrak with daily updates. Search by NORAD ID, COSPAR ID, operator, country, or orbit type.
Curated views for the most interesting questions — what's in LEO, who operates the most satellites, what launched this year — ready to share.
