An interesting update at Newscientist.
Seems they are planning on using Spirit's RAT to dig down into the dirt, cm by cm. I wonder how deep they can go? Maybe we'll find out if there is anything frozen/liquid just below the surface. Link |

Details on the 'dig'! QUOTE Spirit will use the brush on the rock abrasion tool to carefully sweep away soil, much the way an archaeologist uses a brush to uncover artifacts. At each level, Spirit will measure the mineral and chemical properties and assess the physical nature (such as grain size, texture, hardness) of the material, using the Athena science instruments on the robotic arm. What rotation speed(s) does the brush use? Apparently Spirit's wheels won't turn again for 4 months. Oh well, at least Oppy's going to be moving. -------------------- My Grandpa goes to Mars every day and all I get are these lousy T-shirts!
