Aerospace vehicles are always using a FAA DO-178B level A certified rtos, whichever happens to be installed on this - I don't recall at the moment - but it sure as hell isn't Microsoft Windows. FYI -- the third party file system became full, as such, they never wrote an exception trap handler for this(nobody's OS can recover without the proper exception trap handlers) -- that was a classic example of a failure in not anticipating the unforeseeable(even years from now) -- something we as engineers get paid to do -- and not performing a stringent regression test for a user application simulating long time periods -- although the project was planned to last only 90days(but actually lasted a lot longer)-- something which a project engineer is expected to define, to make sure the engineers did their job right - as such it which was circumvented afterwards when a more realistic scenario was experienced in the real world(space). BTW, the Mars Exploration EDL vehicle (which transported the rover) also used VxWorks and it happened to work flawlessly Flight vehicles have more stringent testing requirements than land vehicles. =Dan sorry for getting off-topic here [ = http://www2.applegate.org/~ragooman/ ]
