The original reconnaissance by Voyager and new results from Galileo suggest the possibility of a liquid water ocean beneath the ice of Jupiter's moon Europa. Because the electrical properties of rock, ice, and liquid water differ greatly, detection of a discrete ice/water or ice/rock boundary beneath the ice is possible. Here we demonstrate that a 6-m-wavelength radar could detect an ice-water interface about 20 km beneath the surface, given reasonable assumptions about the properties of Europan ice.
