Fixes at least 50% of my problems at work....run out of troubleshooting ideas? Power cycle.

Not so much. I work with motor drives that often have a "fire mode." It's for critical processes that must happen regardless of any fault codes, like in life-safety equipment.

I always remember it as, "this thing will keep running even if it's on fire," like a BattleBot.

I don't know how NASA's using it here exactly. Like if they had to put it into fire mode to reset it, or they reset it into fire mode to make it ignore whatever the problem was. It's a real thing though.

Edit: Nevermind, the article continually calls it a "firecode" reset after the title. No idea which one is the typo, and I don't know what a firecode reset would be.
