Science instruments selected for NASA’s Europa mission

NASA has selected nine science instruments for a future mission to Jupiter’s moon Europa in which a spacecraft would make multiple close flybys of the icy world — thought to contain a global subsurface ocean — to investigate whether the mysterious moon could harbour conditions suitable for life.

Briny seas maybe lurking on Europa

A decade-long question about the nature of dark spots on Europa’s surface has potentially been solved, with scientists suggesting that these spots are likely signs of irradiated sea salt from a subsurface ocean, deposited onto the surface through interactions with its rocky seafloor. If this is indeed the case, then these findings are an important consideration for assessing the habitability of the planet and whether it could support life or not.
