Despite being arrayed in a dazzling display of colors (whether in stripes or spots), Jupiter is not one of the safest locations to establish a colony thanks in part to radiation (with the only exception being the lunar moon Callisto).
In order for humanity to survive upon Jupiter’s other moons, we may need to create a radiation map for future settlers.
(Astrobiology Magazine) It’s dangerous to remain too long inside the radiation belts of Jupiter. The high-energy particles can damage space probes, and they also can destroy biological molecules or other signatures of life that might exist on inner moons like Europa. A new study plans to determine just how hazardous an impact the radiation belts have on the Jovian system. […]
Patterson and his colleagues are building a detailed map of the surface of Europa and another map of its sister moon Ganymede. The project—led by Louise Prockter of John Hopkins University as part of NASA’s Exobiology and Evolutionary Biology program—will identify dead zones where radiation would likely fry any interesting chemical compounds, as well as possible safe havens that might harbor material expelled from the ocean below.
While it is probably doubtful that Europa will visited by anything but robots (as its frozen bare surface is bathed in Jupiter’s deadly radiation belts), its bigger brother Ganymede may show more promise in the long run (especially if adequate shielding is built for the Jovian settlements).
Either way a radiation map will benefit future explorers (and robots) who may be able to locate valuable resources upon Jupiter’s Galilean satellites.
