Balancing cost and science: NASA examines less expensive mission design for Europa lander

The push for a return mission to Jupiter’s moon Europa has been gaining steam in the last few years, with NASA now planning for Europa Clipper, which would make repeated close flybys to study the moon’s interior ocean and the exciting potential for life. There …

A new look at ‘ocean worlds’: James Webb Space Telescope will target Europa and Enceladus

NASA’s upcoming James Webb Space Telescope (JWST) will be used to study two of the most fascinating moons in our Solar System  – Europa and Enceladus, also known as “ocean worlds” since both have global oceans of water beneath their outer icy surfaces. The new …

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.

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.
