SLS DEB, 55904

Orbit data source: Space-Track

SLS DEB, 55904 is space debris in LEO originally from a launch on Wed, 16 Nov 2022 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.
