The ELaboratore Immagini TElevisive Space 2 (ELITE-S2) investigated the connection between the brain, visualization, and motion in the absence of gravity. ELITE-S2 provides a system for observations on body motor control during long-term exposure to microgravity and performs quantitative data collection and analysis on board the International Space Station (ISS). The primary goal of ELITE-S2 was to study the strategies for dynamic control of posture and body motion and adaptive mechanisms which allow adjustment of motor control strategies resulting from exposure to microgravity. ELITE-S2 investigated whether gravity representation also affects mental imagery of an interceptive task in microgravity. In addition, it examined the effects of weightlessness on breathing mechanisms.

To better understand the neural mechanism for motor control in microgravity, the ELITE-S2 analyzes movement of crewmembers from sitting to standing while monitoring the quantitative postural response to optokinetic stimulation (visual tracking of motion). The role of sensory inputs in the organization of the locomotion patterns and the role of sensorimotor integration mechanisms are evaluated during pointing and reaching tasks. Cardiorespiratory physiology is examined by quantitatively analyzing the chest wall compartment mechanics. To aid in ergonomic design and human factors for future spacecraft design, this investigation also evaluated working posture.
