One of the first visitors to Jupiter’s icy moon of Europa could be a tiny submarine barely larger than two soda cans. The small craft might help strike the right balance between cost and capability for a robotic mission to look for alien life in the ocean beneath Europa’s icy crust.

The idea for the incredible shrinking submarine originally came from NASA’s Jet Propulsion Laboratory (JPL) in California and Uppsala University in Sweden. Such a vehicle would help keep mission costs low at a time when launching objects into space can still cost tens of thousands of dollars per kilogram. The mission concept also would have the advantage of only requiring a small borehole drilled through the ice covering Europa’s surface.
