NASA release details of Submarine concept for Titan mission.

NASA is planning to develop a submarine to send it to giant Saturn's moon Titan by 2040.

Titan is biggest moon of Saturn, it has a methane cycle similar to earth's water cycle and hydrocarbon ocean on its surface. The rain occurs on the moon in the form of methane forming lakes, rivers and valleys.

The submarine would be designed to travel 2,000 kilometer (1,250 mile) on a ninety-day voyage to investigate the depths of the alien marine atmosphere.

Titan’s largest sea, Kracken Mare, will be the destination of the submarine.

“This craft will autonomously carry out detailed scientific investigations under the surface of Kraken Mare, providing unprecedented knowledge of an extraterrestrial sea and expanding NASA’s existing capabilities in planetary exploration to include in situ nautical operations,” NASA said in a statement.

“Sprawling over some 1,000 kilometers, with depths estimated at 300 meters, Kraken Mare is comparable in size to the Great Lakes and represents an opportunity for an unprecedented planetary exploration mission,” they added.

The submarine will be carried to Titan by a spacecraft similar to the X-37 Orbital Test Vehicle. The spacecraft would decelerate on contact with Titan’s dense atmosphere and glide into Titan’s Kraken Mare, where the submarine would be ejected from the spacecraft.

The submarine will measure the alien sea’s chemist try, currents and tides, as well as hunt for evidence of organic life.

The submarine will need to come at the sea's surface level to transmit data directly to earth via its antenna.
