DELTA 1 R/B, 979

Orbit data source: Space-Track

DELTA 1 R/B, 979 is space debris in SSO originally from a launch on Fri, 22 Jan 1965 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.
