ESA (European Space Agency) astronaut Tim Peake seen during his
first spacewalk. Peake and NASA astronaut Tim Kopra 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.
