Astronaut Susan J. Helms, payload commander, measures the distance between Jean-Jacques Favier’s head and the luminous torque, used for the Canal and Otolith Interaction Study (COIS) on the Life and Microgravity Spacelab (LMS-1) mission. Favier, representing the French Space Agency (CNES), is one of two international payload specialists on the almost-17-day flight. This view shows the Voluntary Head Movement (VHM) segment of the experiment. The VHM is meant to characterize how the coordination of head and eye movement changes as a result of spaceflight. Since most vestibular functions are influenced by gravity, the COIS experiment is meant to measure response differences in microgravity.
