ARIANE 44P+3 R/B

ARIANE 44P+3 R/B is a spent rocket body associated with France, launched on 1995-11-17 from Guiana Space Centre, Kourou on the ISO launch. With over 31 years in orbit, it has far exceeded many satellites’ design lifetimes. It orbits in Highly Elliptical Orbit (HEO) at altitudes between 758 km and 73,902 km with an inclination of 5.7°. It travels at approximately 10,872 km/h (3.02 km/s), completing one full orbit every 25.3 hours — that’s roughly 0.95 orbits per day. Its orbital eccentricity of 0.8369 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 ARIANE 44P+3 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.

ARIANE 44P+3 R/B follows a Highly Elliptical Orbit, sweeping between 758 km (perigee) and 73,902 km (apogee). It spends most of its 25.3 hours orbital period near apogee, effectively loitering over a region of interest before rapidly sweeping through perigee — a profile used for high-latitude communications (Molniya orbits), early-warning systems and magnetospheric science. Within ±50 km of ARIANE 44P+3 R/B’s average altitude, there are currently 4 active payloads and 4 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 5.7°, ARIANE 44P+3 R/B passes over latitudes between 5.7°N and 5.7°S, concentrating coverage over equatorial and near-equatorial regions. Low-inclination orbits maximise revisit rates over specific tropical zones. France operates approximately 115 active satellites in total.
