If there is extraterrestrial life in our solar system, there’s a good chance it’s somewhere in the oceans of Jupiter’s moon Europa. The problem? Those oceans measure three times the volume of what we have on Earth and are hidden under an ice crust thousands of meters deep. Researchers at Virginia Tech hope to explore it using a melt-probe, which they describe as “basically a heavy, heated torpedo,” to penetrate the ice and release a free-swimming glider that would navigate the oceans and somehow send information back to Earth.
