THOR ABLESTAR R/B, 953
Orbit data source: Space-Track
THOR ABLESTAR R/B, 953 is space debris in LEO originally from a launch on Sun, 13 Dec 1964 UTC launched from the Air Force Western Test Range (AFWTR). 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.
