Planetary scientists strongly suspect that Europa, one of the four large moons of Jupiter, has a deep ocean beneath its icy surface. There is speculation that the ocean could contain more liquid water than in all of the oceans on Earth, and that has made Europa a focus in the search for life beyond Earth, reports The Washington Post.
NASA also disclosed that a Titan Saturn System Mission [video] remains high among exploration priorities despite being trumped by the Jupiter System Mission. The planned flagship flight would include a NASA-built orbiter to study Saturn and its moons, as well as European lander and research balloon to continue the exploration of the planet's cloud-covered moon Titan. Saturn's moon Enceladus, which harbors ice-spewing geysers, is also major target for that mission, reports MSNBC.
