The time a crowdfunded group of engineers were able to communicate with and take command of a 36 year old interplanetary spacecraft. The ISEE-3 reboot project was one of the most impressive projects I've ever followed along in realtime....12 years ago I had no idea I'd be telling the story to a wide audience. Many of the source documents i used are publicly available here: https://voyager.gsfc.nasa.gov/Library/ISEE_library.html Some were provided to me through Jacob after going through export control. I am unfortunately unable to share all of those here just in case someone made a mistake somewhere and shared something classified. However, everything discussed in the video is available in public records (usually from the link above). Yes, ITAR is incredibly silly, but no I don't want to accidentally get someone in trouble over a 50 year old spacecraft.
