Parazynski during STS-120 EVA 1

ISS016-E-006493 (26 Oct. 2007) --- Astronaut Scott Parazynski, STS-120 mission specialist, uses a digital still camera to expose a photo of his helmet visor as he participated in the first of five scheduled sessions of extravehicular activity (EVA) while Space Shuttle Discovery is docked to the International Space Station. Also visible in the reflections are the station and a blue and white Earth. In just over six hours, Parazynski and Doug Wheelock (out of frame), mission specialist, installed the Harmony module in its temporary location on the station, readied the P6 truss for its relocation during the second EVA session, retrieved a failed radio communications antenna and snapped shut a window cover on Harmony that opened during launch on Discovery.
