DELTA 1 R/B, 515

Orbit data source: Space-Track

DELTA 1 R/B, 515 is space debris originally from a launch on Thu, 13 Dec 1962 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.
