IEEE Spectrum: Space Station: Internal NASA Reports Explain Origins of June Computer Crisis
In the weeks that followed the crisis and apparent recovery, station commander Fyodor Yurchikhin and his fellow cosmonaut Oleg Kotov disassembled the boxes and cabling and inspected every angle of the hardware, occasionally assisted by their American crewmate, Clayton Anderson. Multiple scopes and probes had failed to find the flaw, but their eyes and fingers eventually did.
The connection pins from the power-monitoring device they'd bypassed earlier, they found, were wet—and corroded. The final report described the “change in appearance” of fasteners on one box's connectors and noted “the presence of deposits and residue on the housings, and residue and spots on the contact surfaces.”
