Areosynchronous orbit

Areosynchronous orbits are class of synchronous orbits for artificial satellites around the planet Mars. As with all synchronous orbits, an areosynchronous orbit has an orbital period equal in length to Mars's sidereal day. A satellite in areosynchronous orbit does not necessarily maintain a fixed position in the sky as seen by an observer on the surface of Mars, however such a satellite will return to the same apparent position every Martian day.

The orbital altitude required to maintain an areosynchonous orbit is approximately Script error: No such module "convert".. If a satellite in areosynchonous orbit were to be used as a communication relay link, it "would experience communications ranges of Script error: No such module "convert"." to various points on the visible Martian surface.[1]

An areosynchronous orbit that is equatorial (in the same plane as the equator of Mars), circular, and prograde (rotating about Mars's axis in the same direction as the planet's surface) is known as an areostationary orbit (ASO). To an observer on the surface of Mars, the position of a satellite in ASO would appear to be fixed in a constant position in the sky. The ASO is analogous to a geostationary orbit (GSO) about Earth.[citation needed]

Although no satellites currently occupy areosynchronous or areostationary orbits, some scientists[who?] foresee a future telecommunications network for the exploration of Mars.[citation needed]
