COSMOS 1579 COOLANT, 26520
Orbit data source: Space-Track
COSMOS 1579 COOLANT, 26520 is space debris in LEO originally from a launch on Fri, 29 Jun 1984 UTC launched from the Tyuratam Missile And Space Complex (TTMTR). Debris objects in space refer to the collection of defunct objects orbiting the Earth. Examples of debris include non-operational satellites, rocket bodies, and fragments generated from explosions, collisions, or faulty payload assembly.
