Aims:

Evidence from the Apollo Medical Summit and from video analyses of falls indicated that the high and aft CG of the Apollo EVA suits caused significant instability for several crewmembers.  The current studies will identify and refine the range of acceptable CG locations for prototype exploration EVA suits that permit crewmembers to perform critical mission tasks effectively and efficiently. The following studies have been completed to address this task: CG Assessment (during Exploration Scenario activities); Optimal Weight of Suit Assessment (during Exploration Scenario activities); EVA CG Assessments; EVA CG & Optimal Suit Weight Assessments; EVA Optimal Suit Weight; EVA Work Efficiency Index (WEI) assessment; Constellation Program (CxP) EVA Systems Test 3 - Effect of Center of Gravity on Metabolic Costs and Biomechanics of Ambulation in a Planetary Suit; Effect of Center of Gravity and Suit Weight on Human Performance in Partial Gravity; EVA CG Assessments; EVA CG & Optimal Suit Weight Assessments; EVA Optimal Suit Weight; EVA CG Assessments; EVA Optimal Suit Weight; EVA Work Efficiency Index (WEI) assessment; Exploration Scenario 2; EVA CG Assessments; EVA Optimal Suit Weight; Task Efficiency; EVA Work Efficiency Index (WEI) assessment; EVA CG Assessments; EVA Task Efficiency Index (TEI) assessment; EVA Work Efficiency Index (WEI) assessment; Integrated Parabolic Flight Test: Effects of Center of Gravity & Mass on the Biomechanics, Kinematics, & Operator Compensation of Exploration Tasks in Lunar Gravity.  Pending future exploration missions, additional studies may be required.


Integration/Unique Aspects: These studies are being coordinated and performed by a cross-center team that includes personnel from Constellation EVA Systems Project Office, and Life Sciences (ABF, EPSP, ECP, Neurosciences).
