چکیده انگلیسی
We present a preliminary design for a 3â¯kg expendable measurement system to descend to a depth of up to 1â¯km in the cryogenic hydrocarbon seas (Kraken and Ligeia Mare) of Saturn's moon Titan. These could profile the temperature and gross composition (methane/ethane) and providing information on the constitution of the seabed. Particular features of the Titan environment distinct from Earth are (1) the interior of this small vehicle must be thermally isolated from the 94â¯K liquid (2) 1â¯km depth on Titan entails overpressures of only 10â¯bar, and (3) that the low dielectric loss of the liquid allows data transmission by radio link. A surface vessel equipped with such expendable dropsondes could accomplish much of the science previously considered for submersible vehicles, while avoiding the challenges of buoyancy control.
