A Ganymede orbiter proposal also included a design for a Juno-like radiation vault. However, because the radiation is less at
Jupiter's moon Ganymede and the orbiter's path, the vault would not have to be as thick, all else being similar. One reason the radiation is strong at Jupiter, but confined to

The vault is one of many features of the mission to help counter the high radiation levels near
Jupiter, including an orbit that reduces time spent in the highest radiation regions, radiation-hardened electronics, and additional shielding on components. The
