Maintaining health and physical condition of astronauts during long-duration space missions requires measures to prevent microgravity effects. At present, such measures consist in practicing certain physical exercises, in using elastic suites, as well as in special medication. However, the efficiency of these solutions is limited. An alternative approach, technologically more difficult, but considerably more efficient, consists in producing a state of artificial gravity in the module inhabited by the crew. Such a ...

Long-duration human space flights involved by interplanetary journeys or space station missions expose the crews to effects of weightlessness. Such effects, consisting in loss of bone density, skeletal muscle atrophy, cardiovascular deconditioning etc., can raise significant risks on the health of the astronauts and for their capacity to accomplish the missions. Therefore, a large number of studies were dedicated to solutions for creating artificial gravity. The paper studies dynamic effects produced in a tethered...
