DELTA 1 R/B, 3315
Orbit data source: Space-Track
DELTA 1 R/B, 3315 is space debris originally from a launch on Thu, 04 Jul 1968 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.
