NASA is designing a robot submarine to explore the ultrachilly, hydrocarbon-filled seas on Saturn’s moon Titan — the only body in the solar system, apart from Earth, with liquid on its surface. Researchers have been testing the probe with a bucket-sized mock alien ocean in a lab.
The seas of Titan are very different from their counterparts on Earth: instead of seawater, Titan’s seas consist mainly of a frigid mixture of methane and ethane, at a temperature of around minus 300 degrees Fahrenheit (minus 184 degrees Celsius). That’s what NASA’s Cassini spacecraft and its Huygens probe, which landed on Titan in 2005, found.
