Radiation Design Considerations for Advanced Jupiter Spacecraft

This paper considers one aspect of the complex radiation design considerations for planetary spacecraft, namely the approach used for solving the effects of radiation on materials problems. An overview of the approach developed at JPL for Voyager, and currently being used on Galileo, is treated briefly. Examples of the postulated Jovian charged particle levels are given. The types of computer analyses codes used, the mass shielding techniques that evolved, and the recommended shielding techniques for future planetary spacecraft are treated.
