“…The use by astronauts of three-dimensional spacecraft volume, body restraints to perform tasks (29,78), and changes in movement strategies as a result of the lack of gravity can be studied only with high fidelity in a true 0 g setting such as parabolic flight. Nevertheless, many of the anthropometric effects of 0 g on the body are time dependent and express themselves fully only after extended time in space.…”

Ground-based analog facilities have had wide use in mimicking some of the features of spaceflight in a more-controlled and less-expensive manner. One such analog is parabolic flight, in which an aircraft flies repeated parabolic trajectories that provide short-duration periods of free fall (0 g) alternating with high-g pullout or recovery phases. Parabolic flight is unique in being able to provide true 0 g in a ground-based facility. Accordingly, it lends itself well to the investigation of specific areas of human spaceflight that can benefit from this capability, which predominantly includes neurovestibular effects, but also others such as human factors, locomotion, and medical procedures. Applications to research in artificial gravity and to effects likely to occur in upcoming commercial suborbital flights are also possible.

“…Early designs for spaceflight hardware and human-machine systems were based on body shapes and postures in a 1g environment, such as upright standing or sitting postures. However, positioning and maintaining the body segments off from the NBP required strength exertions, potentially inducing fatigue and discomfort (Tengwall et al, 1982;Vogler, 2005). Thus, newer system designs have adopted an estimated NBP as a design reference.…”

The neutral body posture (NBP) has been characteristically observed from crewmembers in a 0 g space flight. This study quantified the NBP from International Space Station crewmembers using a new technique for structured camera calibration and multiple-camera 3D triangulation. Template manikins derived from 3D body scans of the individual subjects also were used to improve accuracy. A skeletal link system was embedded in the manikin and articulated to reproduce the posture matching with the calibrated video images. The estimated body shapes and postures were compared against the NASA Technical Standards. The NBP, as more reliably estimated from this study, can help to improve spaceflight hardware and spacesuit design.
