When saying "we", do you mean you write code for the space missions? Writing only happy path code as a standard practice in the space sector seems quite absurd

When saying "we", do you mean you write code for the space missions?
Writing only happy path code as a standard practice in the space sector seems quite absurd. You won't ever achieve absolute precision and errors do happen, yet it seems like systems recover most of the time.
Recently, the antenna of Voyager 2 got misaligned, but it is expected to recover from that. That was only the last problem it encountered over its very long mission - and it managed to recover from all of those so far!

- stall84 3y agoVoyager's programming just brings joy to me to think about.. I mean it's the system as a whole (of course) .. but the fact that they've been capable of flying through the environments they have been, using points of light to align themselves, among other things.. for decades .. and recover from incidents.. is just something I marvel at.
- jacobwilliamroy 3y agoWow I can't believe I didn't hear about this. It was all over the news when they broke it, so I figured it would be just as widely reported when they fixed it. It's been almost 3 weeks.
- SamBam 3y agoThere was definitely a prominent NYTimes story when it was fixed, that's how I heard about it.
- abecedarius 3y agoThere was a NASA project to start developing flight software that's smarter in this kind of way, the Remote Agent. It got an award after flying, but if they continued that line of research I haven't heard about it. https://ntrs.nasa.gov/api/citations/20000116204/downloads/20000116204.pdf https://ntrs.nasa.gov/api/citations/20000116204/downloads/20...

- numpad0 3y agoTrying to hand roll a super robust AI software usually backfires. Emergency mode triggers right in the middle of the happy path and ruins your uh, a day if you're lucky. They know that, even I kinda know that.
