2030 is going to be a big year for those curious about life in the solar system. The Europa Clipper spacecraft that just launched is going to arrive in the orbit of Jupiter and begin the exploration of its moon Europa. The following year, a second spacecraft, the Jupiter Icy Moons Explorer (Juice) mission, will join Europa Clipper.

The moons of Jupiter and Saturn are more likely to harbor life than Mars since they have more water. Europa is the most promising candidate, followed by Saturn’s moons Enceladus and Titan. The presence of liquid water on the moons of Jupiter and Saturn is probably more important than being in the Goldilocks zone around the sun. The availability of the elements of life (CHNOPS), tides and the availability of a rocky sea floor also increase the odds of life

Finding definite confirmation that life exists on Europa or any of the other outer solar system moons will take a long time. It will require sending landers, and none of those are currently beyond early planning stages. As Kevin Hand observes in Alien Oceans:

The missions I have described above may take decades, or evening centuries, to complete. Again, this business is not for the faint of heart. Building robotic spacecraft to explore the solar system is the modern analog of building cathedrals.
