CAPE CANAVERAL, Fla., March 1 (UPI) -- NASA astronauts Terry Virts and Barry "Butch" Wilmore spent Sunday performing the last of three spacewalks to continue upgrading the International Space Station.
The astronauts ran cable and installed antennae to prepare the orbiting outpost for the arrival of new commercial crew vehicles beginning in 2017, according to NASA. New docking ports will be flown up later this year. NASA is streaming the walk live.
