Skimming the Moon – LROC News System
Normally the Lunar Reconnaissance Orbiter (LRO) orbits the Moon in a 50 km altitude, near-circular, polar orbit. The orbit is “near”-circular, as LRO’s altitude can vary between its lowest altitude (periapsis) of 35 km and its highest altitude (apoapsis) of 65-km over a twenty eight day period. If left unattended, the Moon’s lumpy gravity field would further perturb LRO’s orbit, driving the periapsis altitude lower and lower, eventually causing LRO to impact the surface in about seventy days. However, by design LRO has propellant to perform a pair of orbit maintenance (or station-keeping) maneuvers every twenty eight days to keep LRO safely in its 50±15 km near-circular orbit. Since its launch on 18 June 2009, LRO has performed twenty five pairs of station-keeping maneuvers to maintain its orbit.
