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.
There are few aspects of everyday life that aren't touched by the technologies developed for space travel.
We used to have a crew of three on board the space station and even at one time a crew of two people, so it's something we can adjust to.
We've got to get rid of the stuff on the space station somehow. So we do have a pretty significant capability to bring back stuff on SpaceX that you might not imagine.
I don't mean to say it's not fresh on the space station, but there's nothing like new, cold air coming into the capsule.
I am not a great sleeper. I don't think I have ever slept 8 hours straight in the last 20 years.
