S114-E-7266 (6 August 2005) --- The Space Station Remote Manipulator System arm or Canadarm2 appears to be waving good bye to the Space Shuttle as the orbital outpost moves away from Discovery. Earlier, the crews of the two spacecraft concluded nine days of cooperative work. As the Shuttle moved away to a distance of about 400 feet, astronaut James M. Kelly, pilot, began a slow fly-around of the Station, while cameras on each spacecraft captured video and still images of the other. Undocking occurred at 2:24 a.m. (CDT), August 6, 2005.
