Description of Driving Event:

Space Vision System (SVS) targets have become an undue burden during EVA. The requirement to restrain cables away from SVS targets added 45 minutes to 1 hour EVA time and will change during the mission. The EVA community has been informed that the targets can be easily damaged by EVA loads, yet the targets are in or near translation paths. A better understanding of the criticality of keeping the targets free of obstructions and the sensitivity of the targets to EVA contact is required. The SVS community must understand the EVA environment and not place unrealistic constraints on the conduct of the EVA. The EVA Project Office is working with the SVS community to resolve these issues.

Root cause: Insufficient coordination and understanding between the SVS and EVA communities.
