All the Mars Rovers – And Some Scientists

How do the Mars rovers compare in size and features? Here’s a great photo putting it all into perspective. Included are Sojourner, Spirit/Opportunity, and Curiosity, with a couple of testing officials at NASA’s Jet Propulsion Laboratory. ¬†These are not the rovers that were sent to Mars, but are the secondary ones built for testing here on Earth. ¬†They cost a lot of money to build too, so NASA keeps them nice and safe.
