TITAN 34B R/B

TITAN 34B R/B is a spent rocket body associated with United States, launched on 1981-04-24 from Vandenberg SFB, California on the Jumpseat 6 launch. With over 45 years in orbit, it has far exceeded many satellites’ design lifetimes. It orbits in Medium Earth Orbit (MEO) at altitudes between 328 km and 17,059 km with an inclination of 63.2°. It travels at approximately 18,518 km/h (5.14 km/s), completing one full orbit every 5 hours 7 minutes — that’s roughly 4.69 orbits per day. Its orbital eccentricity of 0.5553 gives it a noticeably elliptical path, with significant altitude variation between perigee and apogee. Spent rocket bodies like TITAN 34B 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 34B R/B orbits at an average altitude of 8,694 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 34B R/B’s average altitude, there are currently 1 active payload and 12 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 63.2°, TITAN 34B R/B passes over latitudes between 63.2°N and 63.2°S, covering most populated land masses in both hemispheres. This mid-inclination band balances global coverage with efficient launch energy requirements. United States operates approximately 12,413 active satellites in total.
