ATLAS AGENA D R/B, 2144

Orbit data source: Space-Track

ATLAS AGENA D R/B, 2144 is space debris in LEO originally from a launch on Fri, 08 Apr 1966 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.
