Mars Missions

Spirit and Opportunity Mars Rovers

The 'Spirit' and 'Opportunity' rovers have been on the Mars surface for several years now.  Originally designed for six months of operations on the surface of Mars, they have exceeded all expectations.  Spirit is operating in the vicinity of the Gusev crater and Opportunity is operating on the plateau Meridiani.

The Mars Reconnaissance Orbiter (MRO)

Image from NASA's  MRO website
The Mars Reconnaissance Orbiter was launched on Friday, August 12th, 2005. After a voyage of seven months, MRO entered a temporary elliptical orbit around Mars in March 2006.  After that, MRO used friction from the Mars atmosphere for about six months to achieve a more circular orbit and began reconnaissance of Mars in September 2006. Brouse and enjoy the following websites for information about MRO as well as other NASAS missions:  JPL MRO website and  NASA's MRO Website
