During my time in orbit, I lost bone mass, my muscles atrophied, and my blood redistributed itself in my body, which strained my heart. Every day, I was exposed to ten times the radiation of a person on Earth, which will increase my risk of a fatal cancer for the rest of my life. Scott Kelly atrophybloodbody share on social
It is a little bit surreal to know that you are in your own little spaceship, and a few inches from you is instant death. Scott Kelly bitedeathinch Change image and share on social
What we look for are people that are technically competent. You need a background in a scientific field, whether it's as a scientist, an engineer, medical doctor, or, you know, a person that's in the military with some kind of technical background.

I don't think people have an appreciation for the work that it takes to pull these missions off, like humans living on the space station continuously for 15 years. It is a huge army of hard-working people to make it happen. Scott Kelly appreciationarmycontinuously share on social
A year is a long time to live without the human contact of loved ones, fresh air, and gravity, to name a few. Scott Kelly aircontactfresh Change image and share on social
There are few aspects of everyday life that aren't touched by the technologies developed for space travel. Scott Kelly aspectdevelopeveryday Change image and share on social
People do really well on space missions, but it's the physiological, the medical stuff, the stuff like radiation, loss of bone mass and muscle mass and density. It's those things that we need to figure out. Scott Kelly bonedensityfigure share on social
The thing I like most about flying in space is not the view. The thing I like about it is doing something I feel very, very strongly about. Scott Kelly feelflyspace Change image and share on social
When I look at the clouds over the Earth, and I know how high clouds are, I get a sense we are really, really far above those clouds. I wouldn't call it scary, but I am aware I am in space. Scott Kelly awarecallcloud Change image and share on social
We do a lot of science on the space station. Over the course of the year, there'll be 400 to 500 different investigations in all different kinds of disciplines. Some are related to improving life on earth in material science, physics, combustion science, earth sciences, medicine. Scott Kelly combustiondisciplineearth share on social
