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.
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'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.
