SCOUT B-1 R/B, 8861

Orbit data source: Space-Track

SCOUT B-1 R/B, 8861 is space debris in SSO originally from a launch on Sat, 22 May 1976 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.
