DELTA 1 R/B, 575

Orbit data source: Space-Track

DELTA 1 R/B, 575 is space debris in HEO originally from a launch on Tue, 07 May 1963 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.
