Astronaut Jeffrey N. Williams, who went on to spend over six hours outside the Space Shuttle Atlantis with the International Space Station, gives a confident wave inside Atlantis' airlock. Astronauts Williams and James S. Voss started the spacewalk early and remained ahead of schedule throughout. The astronauts secured a United States-built crane that was installed on the station last year; installed the final parts of a Russian-built crane on the station; replaced a faulty antenna for one of the station's communications systems; and installed several handrails and a camera cable on the station's exterior.
