COLOR 20 JUNE - 7 JULY 1996 STS078-398-032 JOHNSON SPACE CENTER, HOUSTON, TEXAS STS-78 ONBOARD VIEW --- Astronaut Susan J. Helms, payload commander, measures the distance between Jean-Jacques Faviers 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 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.
