Astronaut Sunita L. Williams Expedition 14 flight engineer as construction continues on the International Space Station.

Astronaut Sunita L. Williams, Expedition 14 flight engineer, uses a digital still camera during the final of three sessions of extravehicular activity (EVA) in nine days, as construction continues on the International Space Station. During the 6-hour, 40-minute spacewalk, Williams and Michael E. Lopez-Alegria (out of frame), commander and NASA space station science officer, completed tasks that will allow for the attachment of a cargo platform during the STS-118 mission this summer and relocation of the P6 truss during STS-120 later this year.
