On November 20, 2009 two astronauts from U.S. shuttle Atlantis crew performed the first spacewalk of their current mission to the International Space Station. Spacewalkers Michael Foreman and Robert Satcher completed a 6-hour and 37-minute spacewalk at 04:01 p.m. EST (21.01 UTC). The astronauts installed a spare communications antenna on the exterior of the orbital station, hooked up some cables and greased a robotic arm on the Kibo module. They also managed to do some extra maintenance work scheduled for the second spacewalk of the current STS-129 mission.
