Interesting. You'd think that a custom radiation-hardened x86 or ARM variant would be sufficient. Are there any space exploration vehicles running Linux?

- TkTech 13y agoAbsolutely! Hell, the ISS is all Linux now.
- InclinedPlane 13y agoISS laptops run linux, the ISS control software itself does not run on linux.
- XorNot 13y agoDon't know about exploration, but SpaceX runs Linux for all it's rocket firmware and I imagine Dragon capsules will as well.
- ddeck 13y agoThere was as discussion with John Muratore (SpaceX director of vehicle certification) posted on HN a while back with some interesting notes on this: https://news.ycombinator.com/item?id=6125834 https://news.ycombinator.com/item?id=6125834
- rsynnott 13y agoARM is pretty new as a remotely high-performance thing. x86 is used a bit; the Hubble space telescope has a radiation hardened 486, for instance (originally a 386). A good few spacecraft use radiation hardened PowerPCs, M68Ks, and other common designs. Even that ESA chip isn't anything hugely custom; it's a SPARC-V8 variant.
