Astronauts Mark C. Lee (right), payload commander, and Steven L. Smith, mission specialist, perform the final phases of Servicing Mission 2 (SM2) spacewalk duty using the Shuttle's Remote Manipulator System (RMS). Lee holds a patch piece for Bay #10, out of view, toward which the two were headed. A sample of the patch work can be seen on Bay #9 in the upper left quadrant of the picture.
