First British Space Station Astronaut Takes 'Electrifying' Spacewalk Today

NASA astronaut Tim Kopra and European Space Agency (ESA) astronaut Tim Peake will take venture outside the International Space Station on a spacewalk today (Jan. 15) to repair one of the station's eight vital power channels. Peake is the first British astronaut to visit the International Space Station, and this will be his first spacewalk. Kopra, who has flown once before, went on a spacewalk with NASA astronaut Scott Kelly in December.
