Cosmos 1275 (1981 breakup)

The Soviet navigation satellite Cosmos 1275 disintegrated weeks after its June 1981 launch at ~950 km, one of the earliest major unexplained on-orbit breakups. With no propellant aboard, a battery explosion or a collision with existing debris are the leading suspected causes; its fragments still populate low Earth orbit.

Why it matters

Breakup events like this are why low Earth orbit is now crowded with debris. Space Junk View tracks all 31,328 cataloged objects — including roughly 10,229 pieces of debris — and lets you isolate a single event's fragment cloud to see exactly where its wreckage went. See the full breakup-events hub and our space-debris statistics.
