Inside NASA’s daring $8 billion plan to finally find extraterrestrial life

A darkness has spread over the grim, airless field of ice that threatens to swallow us. Night has come to the nightmare glacier. But then we see the shiny spacecraft, with its four gangly legs extending outward to find purchase on the jagged ice. Within, scientific instruments begin to blink on, one by one. Soon, they will start sniffing for any hint of life on this most alien and mysterious of worlds in the Solar System: the Jovian moon Europa. Through the HoloLens each of us wears, we watch this simulation of what might happen about 15 years from now on the icy, forbidding moon.
