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. A prominent feature of the proposed instrument is the use of a bungee cord as the source of force. This results in a simple, lightweight, and compact structure of the instrument. It also results in a large displacement during the measurement and then the reduction of the effect of change in subject posture. The feasibility of the prototype design has been evaluated by quantifying the body mass of a human subject in a parabolic flight test. The present and future statuses of the space scale are discussed.
