THOR AGENA D R/B, 727

Orbit data source: Space-Track

THOR AGENA D R/B, 727 is space debris in LEO originally from a launch on Sat, 11 Jan 1964 UTC via a THOR SLV-2A AGENA D launch vehicle 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.
