BREEZE-M R/B

BREEZE-M R/B is a spent rocket body associated with Russia (CIS), launched on 2005-12-29 from Baikonur, Kazakhstan on the Americom 23 launch. With over 21 years in orbit, it has far exceeded many satellites’ design lifetimes. It orbits in Medium Earth Orbit (MEO) at altitudes between 6,190 km and 35,338 km with an inclination of 19.7°. It travels at approximately 13,798 km/h (3.83 km/s), completing one full orbit every 12 hours 22 minutes — that’s roughly 1.94 orbits per day. Its orbital eccentricity of 0.5371 gives it a noticeably elliptical path, with significant altitude variation between perigee and apogee. Spent rocket bodies like BREEZE-M 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.

BREEZE-M R/B orbits at an average altitude of 20,764 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 BREEZE-M R/B’s average altitude, there are currently 1 active payload and 11 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 19.7°, BREEZE-M R/B passes over latitudes between 19.7°N and 19.7°S, concentrating coverage over equatorial and near-equatorial regions. Low-inclination orbits maximise revisit rates over specific tropical zones. Russia (CIS) operates approximately 1,286 active satellites in total.
