Jupiter is the most distant target planet for which probes can manage on solar power without RTG's. So spacecraft going there need big panels, intricately folded prior to launch. Likewise I am guessing that the communications antennae need to be larger relative to the spacecraft itself than for probes heading to the inner planets and Mars. So the engineering challenges involved in powering and communicating with Jupiter-bound payloads are bound to be daunting.

So the engineering challenges involved in powering and communicating with Jupiter-bound payloads are bound to be daunting. And it certainly doesn't help that, for a Jupiter-bound mission, you're on a heavy lift rocket. So your delicate science probe that's assembled in a clean room and likely barely be able to support its own weight in earth gravity- will spend several minutes being shaken within an inch of its life (specifications?) and blasted by 150+ decibels of sound energy. As well as go from 1 atmosphere to hard vacuum in a matter of minutes and then from ~85° Fahrenheit to a rotisserie of +250°F and -150°F. |
