Parabolic flight is the only ground-based condition in which weightlessness (0G) can be
created long enough for safely testing changes in human perception and behavior. In
addition to the 0G period, parabolic flight generates equal duration periods of 1.8G,
which present another unique opportunity to test the same responses to hypergravity and
back to 1G.
Spatial orientation perception is a critical subsystem that is used by the central
nervous system in the control of vehicles and other complex systems in a high-level
integrative function. Evidence from space flight research demonstrates that spatial
orientation is altered by the transitions in gravito-inertial force levels (Clément 2011;
Clément & Reschke 2008), transitions corresponding to mission phases particularly
critical for crew safety and mission success. Accurate perception of self-in-space motion
and self-motion relative to other objects is critical for successful operations that
involve motor control e.g. doing an extra-vehicule activity or piloting the spacecraft.
To date, there is only limited operational evidence that these alterations cause
functional impacts on mission-critical operations and control capabilities. Immediately
after space flight, most crewmembers have reported some degree of
disorientation/perceptual illusion, often accompanied by nausea (or other symptoms of
motion sickness), and frequently manifested by lack of coordination, particularly during
locomotion The hypothesis is that alteration in sensorimotor performance induced by
inverted vision is gravity depend: maximum alteration during hypergravity, intermediary
alteration during normal gravity, minimal alteration during weightlessness.
