Space station computers pass final test, Atlantis to come home

It's been a rocky few days in space, but it looks like the crashed Russian computers aboard the International Space Station are back up and running to spec, allowing the crew of Atlantis to depart tomorrow. There's still no word on what caused the computers -- which control vital life support systems, as well as the station's stabilizers and directional thrusters -- to fail, but the leading theory involves a surge from the new solar power array the shuttle astronauts installed. We're glad everything's okay -- but also we're totally curious as to what OS / processor combo they're running up there.
