Line 69:
 
If Elysia Planitium has salts below the surface that can take up water from the atmosphere it might have similar brines too, and if so, perhaps the mole could notice the brines as a more heat conductive layer just below the surface as it starts to drill? Especially if the conductivity varied and was highest in the early morning, it might be the Curiosity brines. Just an idea.
 
For more about these brines see

They will also use the seismometer's recording of the reverberations of the self hammering mole to gain insights into the structure of the regolith - it should be able to detect the interface between rock and regolith that they think should be present and determine the depth of the regolith. It could also detect any strong signals of water rich layers indirectly through changes in the elasticity of the rock.
