... Introduction: The MARSES is the sounding instrument developed of searching for water, water-ice or permafrost layers existing in some depth under the visible surface of Mars. ... The secondary task is to measure the soil properties of the subsurface of Mars, which include porosity, electrical resistance of the liquid phase, thermal conductivity, temperature dependence. ... Physical basis of the TEM Sounding method In the TEM sounding the transmitter and receiver coils are used. ...
