Didn’t they also get a few older (Hubble type) spy satellites to use? I remember a story about that.

#102i once read an article on most probably arstechnica about a nasa enthusiast who found some space probe documentation in someones garage. he goes on to actually use that to communicate with the probe and issue commands. something like the booster had emptied or leaked or something. i am not sure what exactly it was. that was a fascinating read

Solar probe sent to comet, rebooted years later to try to put it back into it's solar mission.

Funny enough, nobody posted the link to the article that says "70% of bugs are memory issues" (or something like that) yet.

#104pushes up glasses I would watch the heck out of a Twitch stream of their debugging/brainstorming sessions. I always loved the movie Apollo 13 , especially the technical troubleshooting parts.

#106I know that, at different times, NASA has used Forth[1] and Lisp[2] in some of their space applications. Both of these languages offer REPLs that generally accelerate the debugging process, and while your "average" Lisp might be unsuitable for hard real-time applications (due to the presence of a garbage collector, usually without the hard real-time constraints that you can get out of garbage collectors with extreme…

How about a Lisp without the need for garbage collection at all?

>"The rule of thumb is when something is working you don't change it," Hertz said. "We'd like to change as few things as possible when we bring Hubble back into service."
A lesson not taught to any modern software developer. Instead they change things all the time for no real reason other than that they want to change things.
One of the best senior engineers I worked with taught me how to run an outage. The most important thing? Stop what you are doing, take charge, and get everyone else to stop what they are doing.
The best case scenario of a bunch of engineers flailing about on a bridge turning knobs is that you luck into a fix but don't know how you got there. But you're more likely to make things worse.

This would be cool for earth satellites. On the other hand watching a stream involving something on Mars, let alone voyager, would be pretty boring! Send: ls Ok let's take a 20 minute break.

Best programmer. -1 wpm.

My hazy memory is that the NRO offered NASA a few satellite bodies that they could populate with optic systems. Since they were originally designed for monitoring earth they aren’t well suited for capturing data at much longer distances. If I recall correctly I think someone explained that it’s like trying to peer through a straw, it works, but ideally you’d want a much wider field of view. And apparently the James Web telescope handles this much better.

There's no way that's true... maybe 70% of bugs that crash your computer though.
