Signs of wet soil on Mars


 

 

Report: #0070



Mars Photo 1:

The Mars Rover Spirit is skidding with one wheel as it descends from the distant edge of a crater. 


 

The ground isn't dry dust, as we're used to seeing on the Moon—instead, the wheel crushes the soil, and it doesn't crumble like dry earth would. It seems the Martian soil material is moist—or sticky due to some other substance.  Mars Photo 2:

Mars reveals that the ground is moist. One wheel gets stuck and sinks into the damp Martian soil, leaving a trail where the moisture in the Martian ground is clearly visible.

    Cover a large area of ground with cement dust say 1to2in deep and drive through it at 15/20kmh, you will get the same result as in the photo, but there is no water.
