The small, round rock shown here was named The Lamb. Soils found around the Lamb by Mars Pathfinder's Rover were unique. The soils may be an iron oxyhydroxide phase, or they may be a magnetic iron oxide or even a pyroxene. If the soils prove to be an iron oxyhydroxide, they could provide proof of a warmer, wetter past on Mars. This would help answer large questions scientists have about Mars.
