Space Station Computers Partially Restored 158
Raver32 writes with the news that a partial restoration
of computer control was established on the International Space Station (ISS) Thursday. Systems controlling critical elements like navigation and life-support failed on Wednesday. "Flight controllers were able to re-establish some communication with the computers overnight, with Russian engineers working Thursday to restore the rest of the system, NASA space station flight director Holly Ridings said. The U.S. space agency and Russian officials are still trying to determine the cause of a failure affecting multiple computers in the Russian network ... Since an earlier failure on Monday, thrusters on the space shuttle Atlantis have been fired periodically to help maintain the station's position. The Russian and U.S. space agencies said they could extend Atlantis's mission by one or two days to fix the problem. In the worst-case scenario, NASA said the ISS crew members -- two Russians and an American -- may be evacuated from the station."

Of course, if we launched enough smaller ships to where we had multiple birds in the air at any given time, space for evacuation wouldn't be a problem. Just catch the next transport.
Which reminds me, did NASA ever get around to installing the emergency escape craft? I know it was supposed to be a stripped-down capsule, but I don't remember if they just decided to keep something docked at all times instead.

They didn't all die because there's very few disasters on the ISS that would produce near-instantaneous calamity. This particular one means no thrusters, which isn't usually a problem ( gyros work for minor correction ) - it's only bad because if it's not fixed in time for the Shuttle's departure, the shuttle's undocking will disrupt the ISS's position beyond the gyros ability to compensate.

So, they either (a) fix the computers that control the gyros on the space station OR (b) everyone still up there boards either the Soyuz or Atlantis and everyone bails leaving the station to its fiery demise after it tumbles out of control OR (c) the Russians send a progress craft up there with more fuel (does the space shuttle support in flight refueling?) and consumables for the crews (the oxygen generator on the ISS is broken too they say). The space shuttle, as far as anyone without security clearance knows, has never been refueled in flight so it looks like the most likely option is everyone bails (option 'b') unless they can either fix the computers on the IIS (which may require getting new computers on a progress ala option 'c') which seems to be increasingly unlikely at this point. Perhaps Sir Isaac Newton will finally kill a project that Congress and several Presidents have been unable to. There are certainly some scientists that will not be sad to see the ISS go, given its deleterious effects on NASA's budget for other missions.

Maybe there is a design flaw. They ought to have independant power sources. Any decent server has at least two power supplies, that can connect to independant circuits.
Anyway there is a lesson for all you software guys. Bad power can kill any OS.
Also never trust any technology more complicated than a knife and fork.
