Mars Exploration Rover

NASA's Mars Exploration Rover spacecraft family comprised the nearly identical solar-powered Spirit and Opportunity rovers. Each golf-cart-sized rover carried panoramic and microscopic cameras, spectrometers, a rock-abrasion tool, and autonomous-navigation systems to investigate Martian geology and evidence of past water.
