NASA is making plans to send a smart submarine to Saturn’s moon, Titan, so it can autonomously explore the depths of its frigid oceans.

The submarine would probe the freezing liquid methane and ethane oceans that cover the moon’s surface, beaming back valuable data to Earth, cryogenics engineer Jason Hartwig announced at the NASA Innovative Advanced Concepts (NIAC) Symposium last week.

The tech blueprints of the autonomous submarine include a huge communications ‘fin’ on its back that would let it communicate directly with receivers on Earth, covering a distance of around 1,429 million kilometres (886 million miles).
