[ExI] Humans in space need artificial gravity

Aboard the International Space Station (ISS), astronauts rely on a
strict regimen of exercise and resistance training to mitigate the
physiological effects. These include muscle atrophy, bone density
loss, organ function, eyesight, and effects on cardiovascular health,
gene expression, and the central nervous system. But as a recent NASA
study revealed, long-duration missions to Mars and other locations in
deep space will need to be equipped with artificial gravity.


NASA is currently investigating centrifuges and artificial gravity for
space stations and missions to deep space. Examples include the NASA
concept study titled “Non-Atmospheric Universal Transport Intended for
Lengthy United States Exploration” (NAUTILUS-X), a rotating
torus-shaped module that would provide artificial gravity.
As NASA and other space agencies send astronauts to the Moon (to stay
this time) and pursue crewed missions to Mars and beyond, artificial
gravity may become a regular feature of spacecraft, space stations,
and even surface habitats.

Leaving Earth long-term is really difficult for humans.
