English: Expedition 20 flight engineer Nicole Stott participates in the STS-128 mission's first space-walk as construction and maintenance continue on the International Space Station. During the six-hour, 35-minute space-walk, Stott and astronaut Danny Olivas (out of frame) 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 and Materials International Space Station Experiment from the Columbus laboratory module and installed them on Discovery's payload bay for return.
