This article contains a pictorial tour complete with descriptions of the top ten discoveries by the robotic Martian rovers, Sprit and Opportunity. These rovers have allowed scientists to gain huge insight into the geology of Mars. Originally designed to explore Mars for just 3 months, these rovers continue to scour the surface for clues to the secrets of Mars 3 years after their arrival. Some of the top ten contributions of these rovers include…
*stunning visual images of Victoria Crater
*the presence of basaltic rock, hinting at ancient activity of water on Mars
*a meteorite resting on the ground (the first discovered on another planet)
*high concentrations of sulfur in Martian rocks
*film clips of dust devils, one of the few active processes that shape the surface of Mars in present times
*Hard evidence that Mars was once a wet planet
-silica rich soil
- ‘blueberries’ and rippled rock layers which could only be formed if water once flowed on the Martian surface
