What would a submarine to explore the liquid methane seas of Saturn’s Moon Titan look like? NASA has unveiled an innovative 2200-pound submarine design that would explore both the shoreline and the depths of this strange world that has methane rain, rivers and seas. It would be powered by a 1 kW radiothermal Stirling generator, which would not only provide power to propel the craft, but also keep the electronics from freezing.

“Due to the large amount of data that needs to sent to Earth, the submarine needs a large dorsal fin that includes a planar phased-array antenna. While operating, the submarine would surface for 16 hours per day for Earth communications during which it would study its surroundings using a mast camera. This is a bonus because the high latitudes mean any break in the Titanian clouds would be rewarded with spectacular views of Saturn on the horizon,” reports Gizmag.
