3 Generations of Mars Rovers
This is just cool to see - the development of the Mars rovers over time. Spirit and Opportunity have been the closest things to celebrities NASA has had in a while, and I for one (especially after the failure of the Russian Grunt sample return mission) hope that Curiosity is able to teach us a whole lot more about the Red Planet.
And yes, I think we should have a human base on Mars, eventually. But unlike Newt, I think that space exploration should be done for profit, not just because.

Three Generations of NASA's Mars Rovers in the Mars Yard
This grouping shows 3 generations of NASA’s Mars rovers from 1997 to 2012 set inside the Mars Yard at the Jet Propulsion Lab in Pasadena, Calif. The Mars Pathfinder Project (front) landed the first Mars rover - Sojourner - in 1997. The Mars Exploration Rover Project (left) landed Spirit and Opportunity on Mars in 2004. The Mars Science Laboratory Project (right) is on course to land Curiosity on Mars in August 2012. Credit: NASA/JPL-Caltech

NASA Mars rovers have come a long way in terms of size and capability since the rebirth of Red Planet surface exploration just 15 years ago – spanning from 1997 to 2012.
To get a really excellent sense of just how far America’s scientists and engineers have pushed the state of the art in such a short time – when the willpower and funding existed and coincided to explore another world – take a good look at the new pictures here showing 3 generations of NASA’s Mars rovers; namely Mars Pathfinder (MPF), the 1st generation Mars rover, Mars Exploration Rover (MER), the 2nd generation, and Mars Science Laboratory(MSL), the 3rd and newest generation Mars rover.
The newly released pictures graphically display a side by side comparison of the flight spare for Mars Pathfinder (1997 landing) and full scale test rovers of the Mars Exploration Rover(2004 landing) and Mars Science Laboratory (in transit for a 2012 planned landing). The setting is inside the “Mars Yard” at NASA’s Jet Propulsion Laboratory, Pasadena, Calif. where the teams conduct mission simulations.
It’s been nothing less than a quantum leap in advancement of the scientific and technological capability from one generation to the next.
Sojourner - NASA’s 1st Mars Rover

Just consider the big increase in size – growing from a microwave oven to a car !
The “Marie Curie” flight spare and the actual “Sojourner” rover on Mars are 2 feet (65 centimeters) long – about the size of a microwave oven. The MER rovers “Spirit and Opportunity” and the “Surface System Test Bed” rover are 5.2 feet (1.6 meters) long – about the size of a golf cart. The MSL “Curiosity” and the “Vehicle System Test Bed” rover are 10 feet (3 meters) long – about the size of a car.
