Wheelock during STS-120 EVA 1

ISS016-E-006490 (26 Oct. 2007) --- Astronaut Doug Wheelock, STS-120 mission specialist, participates in the first of five scheduled sessions of extravehicular activity (EVA) to perform work on the International Space Station while Space Shuttle Discovery is docked to the station. In just over six hours, Wheelock and astronaut Scott Parazynski (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.
