TITAN 3C TRANSTAGE R/B, 8516
Orbit data source: Space-Track
TITAN 3C TRANSTAGE R/B, 8516 is space debris in GEO originally from a launch on Sun, 14 Dec 1975 UTC launched from the Air Force Eastern Test Range (AFETR). 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.
