Living in microgravity

  • Astronauts will face many biological and cosmic challenges. Without Earth’s gravity, astronauts will experience a decline in bone density, reduction in muscle mass, changes in vision, and other physiological and psychological effects.
  • NASA is practicing living in space on the International Space Station. Astronauts test air, food, water, and waste systems – and astronauts are making one-year visits to the station while testing and refining reliable deep space systems.
