ATLAS AGENA B DEB, 3121
Orbit data source: Space-Track
ATLAS AGENA B DEB, 3121 is space debris in LEO originally from a launch on Fri, 19 Jul 1963 UTC via an ATLAS AGENA B 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.
