Juno radiation design and implementation

Juno, the second NASA New Frontiers mission, was launched to Jupiter on August 5, 2011 from Cape Canaveral Air Station onboard an Atlas V launch vehicle. The mission features a solar powered, spinning spacecraft in a highly elliptical polar orbit that avoids much of Jupiter´s highest radiation regions. Developing and operating a spacecraft in the environment of space can be a technical and a programmatic challenge and the Juno Mission has the added challenge of operating in the severe radiation environment of Jupiter. This paper describes the Juno Mission and the preparations, which were required to develop and implement a mission, and spacecraft design to successfully operate in the harsh Jovian environment and provide the desired science returns.
