TITAN 3D DEB

TITAN 3D DEB is a tracked piece of space debris attributed to United States, launched on 1972-10-10 from Vandenberg Space Force Base, United States on the HEXAGON SV-4 launch. After more than 54 years in orbit, it is one of the longest-surviving objects in the space catalogue. It orbits in Low Earth Orbit (LEO) at altitudes between 1,403 km and 1,486 km with an inclination of 95.8°. It travels at approximately 25,709 km/h (7.14 km/s), completing one full orbit every 115 minutes — that’s roughly 12.55 orbits per day. At its current altitude, the estimated orbital lifetime before atmospheric re-entry is thousands of years. As orbital debris, TITAN 3D DEB poses a potential collision risk to operational satellites in nearby orbits and is continuously monitored by the U.S. Space Surveillance Network and other tracking systems.

TITAN 3D DEB orbits at an average altitude of 1,445 km in the uppermost reaches of Low Earth Orbit. At this altitude, orbital decay is effectively zero without active deorbiting, and coverage footprints are significantly larger than lower LEO, though at the cost of higher latency. Within ±50 km of TITAN 3D DEB’s average altitude, there are currently 572 active payloads and 323 tracked debris or rocket body fragments. With an inclination of 95.8°, TITAN 3D DEB passes over latitudes between 95.8°N and 95.8°S, providing near-global coverage including the polar regions. Polar and near-polar orbits are used for reconnaissance, weather monitoring and Earth-observation missions that need to image every part of the planet. United States operates approximately 13,196 active satellites in total, of which 17 share a similar altitude band with TITAN 3D DEB.
