Engineers know how to design submarines on Earth, but building one gets a lot trickier when the temperature drops to -300 Fahrenheit and the ocean is made of methane and ethane.
Washington State University researchers are working with NASA to determine how a submarine might work on Titan, the largest of Saturn's many moons and the second largest in the solar system. The space agency plans to launch a real submarine into Titan seas in the next 20 years.
The researchers re-created a Titan ocean in a laboratory. They have published a paper on their work in the journal, Fluid Phase Equilibria.
