NASA has just released a report on a Europa lander mission. I haven’t read all the way through it (in fact, I’ve just glanced through it), but it seems fairly extensive. The lander design itself seems pretty preliminary. It also looks like a walking “rover,” but the legs are just long in order to allow the lander to safely come to rest on whatever terrain it happens to land on.

The lander would have instruments meant to look for the signs of life. Pretty obviously, the chances of life appearing *anywhere* near the surface of Europa are as close to zero as you can get. However, assuming that many, many kilometers below there is a liquid water ocean, and assuming that there is recognizable life swimming or floating around in the water, chances are fairly good that bits of it, everything from biochemicals on up to actual critters, would get trapped in the ice. Over extremely long periods of time the cold, icy equivalent of geological processes might drag that stuff up to the surface, where it might be detectable.
