7 surprising things NASA’s Scott Kelly learned from 300 days in orbit

What it’s like to spend more than 300 days in space

Astronaut Scot Kelly answers a Reddit AMA from the International Space Station.

Living in space presents lifestyle challenges, with food, exercise, and more. 

 > “Sleeping is harder here in space than on a bed … because the sleep position here is the same position throughout the day. You don’t ever get that sense of gratifying relaxation here that you do on Earth after a long day at work. Yes, there are humming noises on station that affect my sleep, so I wear ear plugs to [bed].”

And don’t even think about what happens if you aren’t careful to cover your mouth and nose when you sneeze.

Kelly also says he “will appreciate nature more” when he’s home on Earth.
