A lot of the data we collect is stuff that has to be analyzed on the ground. For instance, we can't see, you know, bone loss. Our cells, you know, that's something that we'll have to notice with imaging technology when I get back.
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.
