S115-E-05306 (10 Sept. 2006) --- While working to survey the thermal protection system on the Space Shuttle Atlantis, the orbiter boom sensor system (OBSS), attached to the remote manipulator system (RMS) arm was positioned near the shuttle's aft cabin windows. This enabled one of the STS-115 crewmembers to record this digital still close-up image of the Canadian-built system.
