Galileo probe battery program - An historical overview

The Galileo Probe mission to Jupiter required the selection of a battery module design that exceeded the known state of the art in 1977. The choice of the lithium-sulfur dioxide system, a technology then under development for nonaerospace applications necessitated an extensive cell and module development program that ultimately resulted in a space-qualified product that satisfies the severe constraints and requirements of the Galileo mission. The development program drew on the data base and experience then available from other government-sponsored lithium-sulfur dioxide programs and is an example of multiapplication synergism that can be derived from industry and government cooperation.
