DELTA 1 R/B, 738
Orbit data source: Space-Track
DELTA 1 R/B, 738 is space debris originally from a launch on Tue, 21 Jan 1964 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.
