Related to exploration of Europa: If we elect to send a probe to bore through (guessimate) five kilometers of ice to reach the Covered Seas, and have a diameter of 100 mm and length of one meter, how much energy will the probe require to reach unfrozen areas? AND given that figure, is it currently feasible to build a probe that will have an energy supply to do the boring without supply from the surface? (I assume a line connected to the surface so the probe can report results, but not a power line. Note that the comm line will have to be heated so as to prevent freeze lock and allow the probe to proceed.) I'm quite willing to expand on the information provided so far, as best I can.
