ABSTRACT
The Constellation Program is designing a new vehicle based on recently developed anthropometric requirements. These requirements specifY the need to account for a spinal-elongation factor for anthropometric measurements involving the spine, such as eye height and seated height. However, to date there is no existing data relating spinal elongation to a seated posture. Only data relating spinal elongation to stature have been collected in micro gravity. Therefore, it was proposed to collect seated height in microgravity to provide the Constellation designers appropriate data for
their analyses. This document will describe the proccss in which thc bcst method to collect seated height in micro gravity was developed.
