It provided a great deal of evidence that water existed on Mars in the past.
About 250 days, but I haven't checked the exact number. (I guess you mean the Mars Exploration Rover mission.)
There were three missions that successfully landed rovers on Mars. The rovers are:Sojourner - landed July 4, 1997 on mission Mars Pathfinder (functioned 3 months)Opportunity - landed January 4, 2004 on mission Mars Exploration Rover-A (functioned 6 years)Spirit - landed January 25, 2004 on mission Mars Exploration Rover-B (still functioning)NASA is also launching a new rover, Curiosity, sometime between November and December, 2011. It is scheduled to land on Mars on August, 2012.
The lunar rover was first used on the Apollo mission 15.
The Lunar Roving Vehicle (LRV) or lunar rover was a type of surface exploration rover used on the Moon during the Apollo program
The Rover was invented, not discovered. It was first used for the Apollo 15 mission in July/August 1971.
The most recent completed Mars rover mission was the Exploration rover. It lasted until May of 2011 and was there for over 6 years and 2 months.
No, the noun 'rover' is a common noun, a general word for anyone who spends their time wandering.A proper noun is the name of a specific person, place, or thing; for example, a Land Rover (automobile) or NASA's Mars Exploration Rover Mission.

NASA's twin robot geologists, the Mars Exploration Rovers, launched toward Mars on June 10 and July 7, 2003, in search of answers about the history of water on Mars. They landed on Mars January 3 and January 24 PST, 2004 (January 4 and January 25 UTC, 2004). The Mars Exploration Rover mission is part of NASA's Mars Exploration Program, a long-term effort of robotic exploration of the red planet.
