To better observe the process skylab carried three mass measuring devices two small ones experiment m074 for measuring the intake and outgo of each astronaut and a large one experiment m172 with an oscillating chair designed for daily monitoring of the weight of the astronauts. Using an instrument called the space scale the velocities of a target object and a reference mass are measured.

Astronaut body mass measurement. The empty chair oscillated with a period of 0889s what is the mass of an astronaut who oscillates with a period of 215 s when sitting in the chair. The main featur instrument for measuring astronaut body mass ieee conference publication. As weve seen astronauts measure their mass by measuring theperiod of oscillation when sitting in a chair connected to aspring. If the force constant of the spring is 2200 nm her mass is 65 kg and the amplitude of her oscillation is 16 cm what is. Russia came up with a slightly different solution called the body mass measurement. An astronaut uses a body mass measurement device to measure her mass.
Firstly the astronaut has to wrap their legs and body around the device as seen in andrés photo. Nasas space linear acceleration mass measurement device slammd used to measure the mass of iss astronauts. The body mass measurement device on skylab a 1970 rm s space station had a spring constant of 606 nm. Currently crews on board the space station use two devices to calculate their weight. One important quantity was the body mass of the astronauts. The empty chairoscillated with a period of 0866 s.
Using slammd astronauts can accurately measure body mass with the help of newtons second law of motion fma force is equal to mass times acceleration. Here on earth it would be called body weight and would be measured by weighing a person on scales. But astronauts still have mass which they can measure to determine what their weight on earth would be and to let medical researchers track changes in body mass due to deconditioning in orbit. A practical high precision method for measuring the mass of an astronaut under microgravity conditions is pro posed. The body mass measurement device on skylab a 1970s spacestation had a spring constant of 606 nm. Measuring mass on a space station in 1973 nasa put in orbit the space station skylab and its experiments included a careful monitoring of the health of the crew.
Space scale a design of the body mass measurement device bmmd was proposed to obtain a lightweight instrument with sufficient accuracy.
