WASHINGTON, Feb. 21 (UPI) -- Two U.S. astronauts took the first of three spacewalks outside the International Space Station today to create parking spots for so-called space taxis that will ferry crew to and from the station.
Station commander Barry "Butch" Wilmore, 52, and flight engineer Terry Virts, 47, started the spacewalk shortly before 8 a.m. ET for the 6 1/2 hour venture. This is the first of three spacewalks in the next eight days to install wiring for two docking mechanisms for crewed commercial capsules built by Boeing and Space X. It is the first major overhaul of the station since it was completed in 2011.
