Mars Observer - The next Mars mission

ESA's Mars Express Mission – Europe on Its Way to Mars

Introduction In the broad context of planetary science, Mars represents an important transition between the outer volatile-rich, more oxidised regions of the accretion zone of the terrestrial bodies (asteroid belt) and the inner, more refractory and less oxidised regions from which Earth, Venus and Mercury accreted. Its size, the degree of internal activity, the age of its surface features, and...

Overview of the Mars Global Surveyor mission

The Mars Global Surveyor spacecraft was placed into Mars orbit on September 11, 1997, and by March 9, 1999, had slowly circularized through aerobraking to a Sunsynchronous, near-polar orbit with an average altitude of 378 km.

Mars global surveyor mission: overview and status.

The Mars Global Surveyor (MGS) spacecraft achieved a 45-hour elliptical orbit at Mars on 11 September 1997 after an 11-month cruise from Earth. The mission is acquiring high-quality global observations of the martian surface and atmosphere and of its magnetic and gravitational fields. These observations will continue for one martian year.
