Joint NASA/ESA mission proposed to search for life on Europa

Europa is one of the most fascinating places in the Solar System, and is considered to be at or near the top of the list of worlds to search for possible evidence of life. Beneath its outer ice crust lies a deep and dark salty ocean, thought to be quite to Earth’s own oceans. Could that ocean be inhabited, even if just by microbes? Scientists want to know, and now a new proposal calls for a joint orbiter/lander mission between NASA and ESA (European Space Agency), to try to answer that question.

New findings from two ‘ocean moons’ increase possibility of finding alien life

For those who are hoping to find evidence of life somewhere else in the Solar System, there was some exciting news this week. Two moons, Europa and Enceladus, were already thought to be among the best places to search, since both have liquid water oceans beneath their outer icy shells. And now, new data from the Cassini spacecraft and the Hubble Space Telescope has increased the potential for some form of living organisms to be found.

It’s been a long time coming, but NASA’s new mission to Jupiter’s moon Europa now has a formal name: Europa Clipper. The spacecraft, to be launched in the early 2020s, will conduct multiple close flybys of the moon, with the goal of determining just how habitable it actually is. With a global salty ocean just beneath its icy crust, Europa is thought to be one of the best places in the Solar System to search for possible alien life.
