Titan Submarine : Vehicle Design and Operations Concept for the Exploration of the Hydrocarbon Seas of Saturn's Giant Moon.

February 10, 2015 via - NASA, 46th Lunar and Planetary Science Conference (2015)

 

Saturn's frigid moon Titan, visited by the Huygens probe in 2005, has a thick atmosphere and three vast northern polar seas of methane and ethane : these seas are of particular interest for future explora- tion. These seas have a composition and conditions (1.5 bar, 92K) rather similar to those of Liquefied Nat- ural Gas (LNG) on Earth. The largest, Kraken Mare, is 1000km in extent but of unknown depth: its complex shoreline morphology and evaporite deposits mapped by Cassini hint at a rich chemistry and climate history. We have developed a practical design for a robot sub- mersible to explore this exotic environment, drawing on experience in terrestrial AUVs/UUVs as well as spacecraft systems. The proposed ~1-tonne vehicle, with a radioisotope Stirling generator power source, would be delivered to splashdown circa 2040, to make a ~90-day, ~2000km voyage of exploration around the perimeter, and across the central depths of, Kraken
