Anyone got info on the software/hardware specs and how they approach prioritizing and storage management? We waited a long time for the Apollo code to make it to Github--what better way to rope in the interest of one segment of humanity than getting more eyes on the code? I imagine that there wasn't time or power to do patches...but if there was, even the mechanics of that would be fascinating. Has anyone ran across a good discussion around the computational aspects of New Horizons? |

Some basic info on communication. The wikipedia page has a lot of info.
The most important parts are that it has a redundant pair of 8GB flash drives and they actually upgraded the code in-flight to use both transmitters at once and nearly double the data rate.
I'm not sure how priorities are arranged but it's all going to be sent back relatively quickly in terms of mission lifetime, and I think they managed storage use mostly by putting in plenty.
