ABSTRACT	Simulating partial gravity on Earth is difficult. Many methods exist;; all have significant limitations. This report focuses on: characterizing the partial-gravity analog environments used during integrated suit tests conducted between 2006 and 2009;; how subjects performed in the two testing environments;; how the test environments compared with each other;; how strengths and weaknesses associated with each environment affected the quality of partial-gravity simulation for human performance testing;; and general lessons learned on usability and features of each environment. The primary partial-gravity analog environments discussed are: the Space Vehicle Mockup Facility partial gravity simulator (POGO), which uses a vertically oriented, manually adjusted, servo-controlled pneumatic cylinder to create a selectable offload of a subject and allows for up to 2.4 m vertical travel;; and the Reduced Gravity Office C-9 parabolic-flight aircraft, which allows unrestrained movement in all 6 degrees-of-freedom and provides a true lunar-gravity kinetic environment with all aspects of subject and suit off-loaded to the same partial-gravity level. We believe a groundbased, partial-gravity analog that has the advantages of POGO while improving on POGO s limitations offers the best primary test bed for characterizing suited human performance. Parabolic flight would then be used for specific tests and limited verification of groundbased simulators.
