Inspection Tool Assessment
• CSA had a desire to image an old potential MMOD strike on the SSRMS
• ISAG developed a plan to use the SPDM arm OTCM camera and DTO VIPIR camera. 
• Video of the area of interest was acquired from several different arm positions and wrist 
rotations to allow creation of stereo imagery for analysis. 
• Provided a valuable test of focused inspection capability using existing and planned ISS 
cameras (VIPIR2 and “Dextre Deployable Vision System” a.k.a. “Dextre Operated Camera”).
