ISS015-E-19120 (23 July 2007) --- Astronaut Clay Anderson, Expedition 15 flight engineer, waves to the camera while participating in a session of extravehicular activity (EVA) as construction continues on the International Space Station. During the 7-hour 41-minute spacewalk, Anderson and cosmonaut Fyodor N. Yurchikhin (out of frame), commander representing Russia's Federal Space Agency, installed a television camera stanchion, reconfigured a power supply for an antenna assembly, and performed several get-ahead tasks. Also, while riding on the end of the Canadarm2, Anderson jettisoned the Early Ammonia Servicer (EAS) by shoving it opposite of the station's direction of travel.
