In this photograph, astronauts Owen Garriott on the body restriant system and Byron Lichtenberg prepare for a Vestibular Experiment during the Spacelab-1 mission. The Vestibular Experiments in Space were the study of the interaction among the otoliths, semicircular canals, vision, and spinal reflexes in humans. The main objective was to determine how the body, which receives redundant information for several sensory sources, interprets this information in microgravity. Another objective was to record and characterize the symptoms of space sickness experienced by crewmembers. The body restraint system was a rotating chair with a harness to hold the test subject in place. The crewmember wore an accelerometer and electrodes to record head motion and horizontal and vertical eye movement as the body rotated. The first Spacelab mission, Spacelab-1, sponsored jointly and shared equally by NASA and the European Space Agency, was a multidisciplinary mission; that is, investigations were performed in several different fields of scientific research. The overall goal of the mission was to verify Spacelab performance through a variety of scientific experiments. The Spacelab-1 was launched aboard the Space Shuttle Orbiter Columbia for the STS-9 mission on November 28, 1983. The Marshall Space Flight Center had management responsibilities for the mission.
