TITAN 3C TRANSTAGE R/B

TITAN 3C TRANSTAGE R/B is a spent rocket body associated with United States, launched on 1978-06-10 from Cape Canaveral, Florida on the CHALET 1 launch. With over 48 years in orbit, it has far exceeded many satellites’ design lifetimes. It orbits in Medium Earth Orbit (MEO) at altitudes between 29,945 km and 41,992 km with an inclination of 10.2°. It travels at approximately 11,046 km/h (3.07 km/s), completing one full orbit every ~24 hours (geosynchronous) — that’s roughly 1.00 orbits per day. Its orbital eccentricity of 0.1423 gives it a noticeably elliptical path, with significant altitude variation between perigee and apogee. At geostationary altitude, there is no meaningful atmospheric drag — this object will remain in orbit indefinitely unless actively deorbited. Spent rocket bodies like TITAN 3C TRANSTAGE R/B are among the largest pieces of uncontrolled space debris and are priority targets for collision avoidance manoeuvres and future active debris removal efforts.

TITAN 3C TRANSTAGE R/B orbits at an average altitude of 35,969 km in Medium Earth Orbit, the region between LEO and GEO (2,000–35,786 km). MEO’s higher altitude gives each satellite a much larger ground footprint than LEO, meaning fewer spacecraft are needed for global coverage — but signal latency is higher and radiation from the Van Allen belts is a significant design constraint. Within ±50 km of TITAN 3C TRANSTAGE R/B’s average altitude, there are currently 54 active payloads and 21 tracked debris or rocket body fragments. This is a relatively sparse altitude band, containing less than 1% of all active satellites. With an inclination of 10.2°, TITAN 3C TRANSTAGE R/B passes over latitudes between 10.2°N and 10.2°S, concentrating coverage over equatorial and near-equatorial regions. Low-inclination orbits maximise revisit rates over specific tropical zones. United States operates approximately 12,413 active satellites in total, of which 16 share a similar altitude band with TITAN 3C TRANSTAGE R/B.
