Jupiter's watery moon Europa is the next big target in the search for life beyond Earth. And the easiest way to search is to get up close and personal — right on the surface.
In February 2015, NASA announced plans for Europa Clipper, a flyby mission. Later in the year, NASA engineers started considering adding a lander.
While Europa Clipper would make wide orbits around Jupiter and close passes to Europa, the lander will get close enough to prod the surface with its sensors.
It could touch down with the help of a skycrane, like the one that delivered the Curiosity rover to Mars.
The lander would carry rotating saws and scoops to dig into the ice of the crust, as well as instruments to look for signs of life.
And it would have about 10 days to do its work because not even robots can stand up to the radiation pouring off Jupiter for long.
It's a short window, and one that's still six years away, but Congress seems to think the science is worth it. Since NASA announced the mission, lawmakers have pumped cash into the Europa program, set launch deadlines for both orbiter and lander missions, and directed NASA to use the Space Launch System to get its probes where they need to go.
