So much incredible info in this article. I've now also followed @NASAJuno.
Juno doesn't just have an interesting target -- it's a very interesting robot for its own sake. Jupiter has some of the most intense radiation in the solar system. In some areas, the electrons surrounding it move nearly at the speed of light. That would tear your average robot's computer to shreds, but Juno is encased in a unique suit of armor to protect it.
I love the story at the end where "these young programmers" couldn’t figure out how to patch the system in the space craft. Instead, they called in a 77 year old retired NASA engineer. Brilliant.
