Outside the International Space Station, Expedition 46 Flight Engineers Tim Kopra of NASA and Tim Peake of the European Space Agency replaced a voltage regulator box on the starboard truss of the complex during a 4 hour, 43 minute spacewalk Jan. 15. The replacement restored full power to the laboratory three months after the failure of the so-called Sequential Shunt Unit resulted in the loss of one of channels that route electricity to the station systems. Kopra and Peake were making their way through other secondary tasks when Kopra reported a small amount of water in his helmet, forcing an early termination to the excursion. The crew was never in any danger and made an orderly return to the Quest airlock where they removed their suits for inspection and further analysis. The spacewalk was the 192nd in support of space station assembly and maintenance, the third in Kopra’s career and the first for Peake.
