TITAN 34D TRANSTAGE R/B

TITAN 34D TRANSTAGE R/B is a spent rocket body associated with United States, launched on 1984-01-31 from Cape Canaveral, Florida on the VORTEX 4 launch. With over 42 years in orbit, it has far exceeded many satellites’ design lifetimes. It orbits in Medium Earth Orbit (MEO) at altitudes between 31,606 km and 40,433 km with an inclination of 6.1°. It travels at approximately 11,039 km/h (3.07 km/s), completing one full orbit every ~24 hours (geosynchronous) — that’s roughly 0.99 orbits per day. Its orbital eccentricity of 0.1041 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 34D 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 34D TRANSTAGE R/B orbits at an average altitude of 36,020 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 34D TRANSTAGE R/B’s average altitude, there are currently 65 active payloads and 28 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 6.1°, TITAN 34D TRANSTAGE R/B passes over latitudes between 6.1°N and 6.1°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 15 share a similar altitude band with TITAN 34D TRANSTAGE R/B.
