Chamitoff during EVA 1

ISS027-E-035206 (20 May 2011) --- NASA astronaut Greg Chamitoff, STS-134 mission specialist, nears the completion of his role in the mission's first session of extravehicular activity (EVA) as construction and maintenance continue on the International Space Station. During the six-hour, 19-minute spacewalk, Chamitoff and NASA astronaut Andrew Feustel (out of fame) retrieved long-duration materials exposure experiments and installed another, installed a light on one of the station's rail line handcarts, made preparations for adding ammonia to a cooling loop and installed an antenna for the External Wireless Communication system.
