A Thermal Drilling Probe for Titan Lake-Bed Ice: Melt Energy, Penetration Rate and Power Sizing

This study sizes the Titan surface system named in its title for operation in the Titan surface environment, and reports the result as SIMULATED, NOT MEASURED. The design is developed from stated physical relations and a shared environmental basis, and every performance figure is computed by the deposited script rather than asserted. Among the computed results are melt energy per metre of penetration of 3.97 megajoules per metre, penetration rate of 0.4 metres per hour, time to target depth of 125.2 hours. Mass and power budgets are assembled from components so that they can be audited, off-design behaviour and materials uncertainty are discussed openly, and the limits of the sizing are stated in full. The probe is a civilian subsurface science instrument that melts a narrow hole into lake-bed ice to emplace sensors and recover samples; it is a research drilling tool with no application beyond peaceful investigation of the lakes.
