There's no specific time limit for how long a rover can last on Mars. Accidents and mechanical failure can affect the ability of a rover to survive. The Opportunity rover has so far been working almost non-stop for seven years. Its twin rover Spirit has not been heard from in almost a year and may no longer be functional.
Probably a while because of the distance of Mars form the earth and how long it takes for radio waves and data to travel through space and be picked up by satellites.
About 250 days, but I haven't checked the exact number. (I guess you mean the Mars Exploration Rover mission.)
According to the Encarta World English Dictionary: "Rover" = Wanderer, somebody who wanders from place to place, never settling anywhere for long.
It would take about 7 months to get to Mars
Curiosity, NASA's Mars rover, was launched on November 26, 2011, and it landed on Mars on August 6, 2012. The journey from Earth to Mars took approximately 253 days for the rover to reach its destination and successfully land in the Gale Crater.

For ever!
It took Curiosity 253 days to land on the planet Mars
Apparently it took curiosity 8 months.
In theory, a Mars Rover could be any size desired. However, there are limits to the size and mass of objects launched from Earth and designed to be hard-landed on the surface. The original Mars rover, Pathfinder, was about 2 feet long. The two Mars rovers currently active, Opportunity and Spirit, are about 5 feet tall, and 6 feet long and wide. On Earth, each would weigh about 385 pounds, but on Mars they weigh less than 100.

Landing on Mars is easy; there are no bodies of water on Mars, it's all solid land. The difficult part is getting there from Earth. It's a long voyage.
As the Mars rover would be on the planet for a long time it would have to use solar energy alone to move around.
