Instrument for measuring the mass of an astronaut
Yusaku Fujii,Kazuhito Shimada +1 more
TL;DR: In this paper, a practical and lightweight instrument for measuring the mass of astronauts under microgravity conditions is proposed, which connects the subject astronaut to the base with a rubber cord and uses an optical interferometer to measure the acceleration of the subject.
Journal ArticleDOI
Balance for Measuring Mass Under Microgravity Conditions
TL;DR: In this article, a method for efficiently and accurately measuring mass under conditions of weightlessness is proposed using the law of conservation of momentum, where the velocities of two different uniform motion states of an object and the reference mass are measured highly accurately using an optical interferometer.
Journal ArticleDOI
Instrument for Measuring the Body Mass of Astronauts Under Microgravity Conditions
TL;DR: An improved prototype of the space scale, which has been proposed as a practical and lightweight instrument for measuring the body mass of astronauts under microgravity conditions in the International Space Station (ISS), has been developed as mentioned in this paper.
Journal ArticleDOI
Mass measuring instrument for use under microgravity conditions.
TL;DR: A prototype instrument for measuring astronaut body mass under microgravity conditions has been developed and its performance was evaluated by parabolic flight tests by measuring the mass of a sample object.

The Space Scale: An Instrument for Astronaut Mass Measurement
Yusaku Fujii,Kazuhito Shimada +1 more
TL;DR: In this article, the velocities of a target object and a reference mass are measured with high accuracy by optical interferometry using an instrument called the "Space Scale" for measuring the mass of an astronaut under microgravity conditions.

Specimen mass measurement
J. Ord,William E. Thornton +1 more
TL;DR: The Skylab specimen mass measurement device was operated throughout the altitude test in close simulation of the 56-day Skylab mission and performed operational specimen measurements well until it was passed out of the chamber for replacement of the specimen hold-down and was autoclaved prior to return.

A direct-reading inertial balance (teaching)
TL;DR: In this article, a balance consisting of two oscillators, weakly coupled, is used for demonstrating inertial mass and for providing a means of measuring it using a flat metal spring.
