NASA Is Planning To Send A Submarine To Titan, Saturn's Largest Moon

NASA has unveiled conceptual plans to send an autonomous submarine to Titan, Saturn's moon, in a bid to explore the vast icy reaches of the Kraken Mare.

At the recent 2015 NASA Institute for Advanced Concepts (NIAC) Symposium in Cocoa Beach, Florida, researchers revealed the Titan Submarine Phase I Conceptual Design, an outline for a mission that could potentially take place in 2040. The ambitious plan would see an autonomous submarine dispatched to sail the near-cryogenic seas of methane and hydrocarbons that exist at the poles of Titan, the largest of which is called the Kraken Mare. Unique among the bodies of the solar system, Titan is one of the few places outside of the Earth where liquid seas and lakes can be found on the surface.

Those seas are far from hospitable, however, requiring a unique design for NASA's proposed submarine drone. The craft would weigh about a ton, and would use electric propulsion to sail across Titan's seas for a 90-day-mission. Due to the distance between Titan and Earth, the submarine's operations would need to be largely autonomous, and the drone would be delivered to the surface by a winged spacecraft, similar to a U.S. Air Force X-37 lifting body. After a hypersonic entry into Titan's atmosphere, the delivery craft would ditch and sink, leaving the submarine floating at the surface.

NASA has proposed other ambitious extraterrestrial ventures for the coming decades as well, including helicopter drones dispatched to Mars and a Zeppelin-style craft to carry astronauts into the atmosphere of Venus. The Compass Team at NASA's Glenn Research Center designed the Titan submarine for the NASA Innovative Advanced Concepts Program.
