Random question.  As I recall the Space Shuttle and the International
Space Station was only using 80386's because they have to be hardened
against radiation/cosmic rays, as well as all of the other mechnical
and thermal stresses associated with being in a spacecraft.  Is there
any newer generation cpu's which are space-cerified at this point?

(Of course, I'm rather doubtful that NASA would ever be willing to use
Linux on something like the Curiosity Mars Rover, but I could imagine
Linux being used in a non-mission critcal system on the ISS....)
