advantage:
1.helps to explore the new planets.
2.which helps us to settle more people
3.1st man made machine to reach such a height collect samples and analyse it
disadvantage:
1.a burden on US tax payers as no big breakthroguh has been made.
2.could cause an imbalnace in the movement of planets coz it shuttle contains nuclear powered cells which could be hazardous their and no 1 could predict the harms.

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.

No they are different rovers.
Mars Exploration Rover
175.4 kilograms
it was invented in 1997
it figured out if we could live on mars or if there was ever life on mars.
The Mars Exploration Rover Opportunity landed on Mars during 2004
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.
The Mars Exploration Rovers (Spirit and Opportunity) and the Mars Science Laboratory rover (Curiosity) use the VxWorks operating system.

The Phoenix lander landed on Mars in May, 2008. It isn't really a rover. It is a lander, doesn't move around like the Mars Exploration Rovers - Spirit and Opportunity.
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.
