ECHO 2 DEB (METAL OBJ), 742

Orbit data source: Space-Track

ECHO 2 DEB (METAL OBJ), 742 is space debris in LEO originally from a launch on Sat, 25 Jan 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.
