Astronaut Tamara Jernigan being 'weighed' in space. As conditions in orbit are without gravity, body weight can not be measured. Instead, the subject's mass is measured using this special chair. As the chair moves back and forth, a timer records how much the crewmember's mass retards the chair's movement. This was one of the instruments used in the Spacelab Life Sciences SLS-1 laboratory flown in the cargo bay of Shuttle Columbia during Mission STS-40 of 5-14 June 1991. All of the seven crew were involved in the multitude of life science experiments in SLS-1, with the overall aim of testing physiological adaptation to microgravity in space.
