For a long time now, there has been growing interest in sending a mission back to Jupiter to better study one moon in particular: Europa. Previous missions such as Voyager and Galileo showed us this world up close for the first time, revealing a place that maybe, just maybe, is home to some kind of life. On the outside, Europa is cold and frozen, like an airless version of Antarctica, with its surface completely composed of ice. But deeper down, as those probes found, there is a global ocean of water deeper than any oceans on Earth. In more recent years and months, a new NASA mission to Europa has finally started to take shape, with a launch tentatively scheduled for 2022. As often happens, however, the mission is facing possible budget cuts in 2017.
This was an exciting and very important week for NASA and planetary exploration: the new NASA budget from Congress is better than expected and, in the words of The Planetary Society, “extraordinary.” There is a healthy increase for planetary science, and one new mission in particular which a lot of people have been waiting for: a new mission to Europa. Not only is it now fully funded, the Congressional plan goes further than the initial mission concept in calling for not just multiple flybys, but also a lander.
An exciting new development in planetary exploration was announced yesterday: NASA has chosen the science instruments which will be included in a new mission to Jupiter’s moon Europa. For those advocating and supporting such a mission, this is welcome news indeed. Europa’s subsurface ocean has become a prime target in the search for possible life elsewhere in the Solar System, and this mission may finally help to answer long-standing questions about this fascinating moon.
Jupiter’s moon Europa, with its subsurface ocean, is considered by many to be the best place in the Solar System to search for extraterrestrial life. With NASA now committing itself to a new mission sometime in the 2020s, the focus is turning to what would be the best strategy for looking for any life which may be there. Over 200 scientists and engineers met at NASA’s Ames Research Center in Mountain View, Calif., last week for a workshop called The Potential for Finding Life in a Europa Plume to do just that.
