GPDM, 100915
AKA "OBJECT AJ" on Space-Track | Orbit data source: Space-Track
GPDM, 100915 is a satellite in SSO that was launched on Thu, 01 Oct 2026 UTC launched from the Air Force Western Test Range (AFWTR). Unknown objects in Earth's orbit typically refer to objects detected orbiting the Earth but have not yet been identified or cataloged. These objects could be anything from previously untracked satellites, spent rocket stages, debris from satellite collisions, or even natural meteoroids temporarily captured by Earth's gravity.
