Astronauts need artificial gravity to prevent deconditioning during long space missions. This study explores a human-powered centrifuge design for the Space Shuttle, analyzing forces and power needs for exercise and artificial gravity.

Area of Science:

  • Space exploration
  • Human physiology
  • Biomedical engineering

Background:

  • Physiologic deconditioning is a significant risk for astronauts on long-duration space flights.
  • Artificial gravity is a potential countermeasure to mitigate these deconditioning effects.
  • Centrifuges are a viable technology for generating artificial gravity.

Purpose of the Study:

  • To present a design study for a human-powered centrifuge for use on the NASA Space Shuttle.
  • To analyze the forces and performance parameters associated with such a centrifuge.
  • To explore the feasibility of using a human-powered centrifuge for astronaut exercise and artificial gravity exposure.

Main Methods:

  • Engineering design analysis of a human-powered centrifuge concept.
