SCOUT X-1 DEB, 3927

Orbit data source: Space-Track

SCOUT X-1 DEB, 3927 is space debris in LEO originally from a launch on Thu, 16 Feb 1961 UTC launched from the Wallops Island (WLPIS). 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.
