graviton1066: iss046e008634 NASA astronaut Tim Kopra and ESA (European Space Agency) astronaut Tim Peake conducted a spacewalk on Jan. 15, 2016 and successfully replaced a failed voltage regulator that caused a loss of power to one of the station’s eight power channels in Nov. 2015. The pair ended its spacewalk early after Kopra reported a small water bubble had formed inside his helmet. -- source link
