TITAN 34D TRANSTAGE R/B, 19490
Orbit data source: Space-Track
TITAN 34D TRANSTAGE R/B, 19490 is space debris in HEO originally from a launch on Fri, 02 Sep 1988 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.
