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.
