STS112-E-5333 (12 October 2002) --- A high angle view of the S0 (S-zero) truss which was photographed during a six hour, four minute spacewalk, the second of three scheduled for the STS-112 mission. Astronauts Piers J. Sellers and David A. Wolf are the assigned spacewalkers for all three. The airlock spur, a route used by spacewalkers to get from the Quest airlock on the International Space Station (ISS) to the outpost's truss, is visible in the upper right portion of the frame.
