ISS020-E-037387 (1 Sept. 2009) --- This is a close-up view of the face of astronaut John ?Danny? Olivas, STS-128 mission specialist, as he participated in the STS-128 mission's first session of extravehicular activity (EVA) as construction and maintenance picked up once more on the International Space Station. During the six-hour, 35-minute spacewalk, Olivas and astronaut Nicole Stott (out of frame), Expedition 20 flight engineer, removed an empty ammonia tank from the station's truss and temporarily stowed it on the station's robotic arm. Olivas and Stott also retrieved the European Technology Exposure Facility (EuTEF) and Materials International Space Station Experiment (MISSE) from the Columbus laboratory module and installed them on Discovery's payload bay for return.
