Researchers as part of NASA’s Exobiology and Evolutionary Biology program are mapping the surfaces of Jupiter’s moons Europa and Ganymede. One goal is to identify ‘dead zones’ where the powerful radiation of Jupiter would likely destroy any interesting organic compounds. The team also hopes to find areas that are possible ‘safe havens’ – where materials expelled from the moons’ subsurface oceans might survive. Such areas could be extremely important sites for future missions to the Jovian system.
