scope:

Physical mockups were used to perform a human factors analysis to improve the ground processing of the Constellation Program's (CxP) Ares-1 and Orion, verify ground processing requirements for flight hardware, and validate ground activities. The inclusion of infrared motion capture analysis with the physical mockups improved the human factors analysis and also helped to facilitate development of detailed work instructions and improve training materials. Analyses were accomplished by first developing a timeline of events that included each activity, and then each activity was analyzed by operability and human factors experts with spacecraft processing experience. A human factors analysis tool was adapted for this activity. Several human factors and operations experts were brought together in a small team to perform this analysis. Following each issue discovered during the analysis, the necessary analysis design engineers were brought into the process to address the issue for design improvements.
