Space has its own unique smell. So whenever a vehicle docks, or if guys are out doing a spacewalk, the smell of space when you open up the hatch is very distinct. It's kind of like a burning-metal smell, if you can imagine what that would smell like.

I would say that as a government employee, I am subject to the Hatch Act.

The ride to orbit was impressive, as it always is. But once I got on board the space station, it really felt like I was visiting an old home; it felt very comfortable.

I'll be helping them getting suited up, getting them in the airlock, getting the airlock prepared, and getting them out the hatch, and then talking them through these three spacewalks.

When you look at the... atmosphere on the limb of the Earth, I wouldn't say it looks unhealthy, but it definitely looks very, very fragile and just kind of like this thin film, so it looks like something that we definitely need to take care of.
