SL-4 R/B, 68753
Orbit data source: Space-Track
SL-4 R/B, 68753 is space debris in SSO originally from a launch on Thu, 16 Apr 2026 UTC via a SOYUZ-2-1B launch vehicle from the Plesetsk Missile And Space Complex (PKMTR). 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.
