Most of what scientists know of Jupiter's moon Europa they have gleaned from a dozen or so close flybys from NASA spacecraft - Voyager 2 in 1979 and Galileo in the mid-to-late 1990s. In these fleeting encounters, scientists have seen a fractured, ice-covered world with signs of a liquid water ocean under its surface. Such an environment could potentially be a hospitable home for microbial life. So if we landed a spacecraft on Europa, what would it look for and what tools would it carry?
