As far as the sounds on the space station, it's pumps, fans, motors, certain modules are louder than others, but it's generally a pretty nice working environment. It's not too loud or too smelly.
From Scott Kelly
The earth is a beautiful planet.
It's for us to take care of the air we breathe and the water we drink. And I do believe we have an impact on that, and we do have the ability to change it if we make the decision 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.
We don't do laundry because that requires a lot of water, and water's at a premium up here. Plus, it'd be pretty complicated, I think, to make a space washer, although I guess you could do it.
It seems like in the beginning of my flight, the space dreams were rare. And now, almost 150 days into it, the Earth dreams are more of the rare ones.
I think what most people miss, and what I missed last time, are the people that are important in your life. You know, the relationships you have with people on the ground.
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.
There are parts of the Earth that are covered with pollution all the time. I saw weather that was unexpected. Storms bigger than we've seen in the past. This is a human effect. This is not a natural phenomenon.
