S73-20622 (March 1973) --- Scientist-astronaut Joseph P. Kerwin, science pilot of the first manned Skylab mission, demonstrates the Body Mass Measurement Experiment (M172) during Skylab training at the Johnson Space Center. Dr. Kerwin is in the work and experiments area of the crew quarters of the Skylab Orbital Workshop (OWS) trainer at JSC. The M172 experiment will demonstrate body mass measurement in a null gravity environment, validate theoretical behavior of this method, and support those medical experiments for which body mass measurements are required. The data to be collected in support of M172 are: preflight calibration of the body mass measurement device and measurements of known masses up to 100 kilograms (220 pounds) three times during each Skylab mission. The device, a spring/flexure pivot-mounted chair, will also be used for daily determination of the crewmen's weight, which will be manually logged and voice recorded for subsequent telemetered transmission.
