The two Tims are going to have a long day outside the ISS.   Tim Kopra of NASA and Tim Peake of ESA (European Space Agency) will primarily perform work to replace a voltage regulator that compromised one of the station’s eight power channels when it failed last November. There will be a link for a live feed (USTREAM) up about an hour before the 12:55 UTC / 07:55 EST EVA.
