NASA’s one-year mission investigates how space affects astronauts’ functional performance

(NASA/Johnson Space Center) Adapting to the microgravity environment of space changes the way your brain interprets sensory signals, decreases muscle strength and alters cardiovascular function. Astronauts will need to overcome these changes to perform critical mission tasks on a journey to Mars. Comparing One-Year Mission preliminary results to six-month data yielded similar findings. Tasks that challenged postural stability, or balance control systems, changed the most as a result of spaceflight.
