NASA astronaut Terry Virts, Flight Engineer of Expedition 42 on the International Space Station, is seen working to complete a cable routing task while the sun begins to peak over the Earth’s horizon in February, 2015. Virts and fellow astronaut Barry “Butch” Wilmore completed a 6-hour, 41-minute spacewalk routing more than 300 feet of cable as part of a reconfiguration of the station to enable U.S. commercial crew vehicles under development to dock to the space station in the coming years.
