OSNews, Generic OSes As the first images of the Mars Curiosity lander start pouring in, let's talk about what operating system it runs. As I found out via Hacker News, the project runs on VxWorks, a very popular embedded operating system used for truly mission critical tasks. I'd love to know just how much work has gone into making it bug-free - this isn't the kind of environment where you want code to fail.

Bugs in space

I know that the Spirit rover had a software bug. Specifically a reboot doom loop. I think it was caused by an excessive number of open files at boot. Though those two rovers also had a setup where the radio had a separate minimal OS that could control the rover OS and was used to supply fixes.
