Astronomy Fun Fact #59

Astronauts in space work out for about 2 hours EVERY DAY!


People don't experience as much gravity in space as they do here on Earth, which puts them at risk of muscular atrophy (muscles wasting away from lack of use).


To avoid this, astronauts have to use special exercise equipment developed by NASA engineers to basically get the same amount of exercise that the typical person gets by walking around on Earth's surface.
