When I look at the clouds over the Earth, and I know how high clouds are, I get a sense we are really, really far above those clouds. I wouldn't call it scary, but I am aware I am in space.

From Scott Kelly

There are definitely parts of Asia, Central America that when you look at them from space, you're always looking through a haze of pollution. As far as the atmosphere is concerned, and being able to see the surface, you know, I would say definitely those areas that I mentioned look kind of sick.

From Scott Kelly

The majority of astronauts have to change their eyeglasses while in space. They bring eyeglasses with them and typically change a few months into the mission.

From Scott Kelly

The workouts have positively impacted the astronauts' bones and muscles, and they are coming back in really good shape. But some are losing bone and muscle but not as much as we saw in the early days.

From Scott Kelly

Just like the bones and muscles, the heart is designed to work in one gravity here on Earth, so when you put the heart in space, it operates differently and changes shape.

From Scott Kelly

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.

From Scott Kelly

I feel more like an environmentalist since I've been up here. 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.

From Scott Kelly

I've flown in space four times now, so it's going to be hard in that respect, but I certainly look forward to going back to Earth. I've been up here for a really long time and sometimes, when I think about it, I feel like I've lived my whole life up here.

From Scott Kelly

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. So we generally throw our clothes out. I think I've been wearing this pair of pants for about two months.

From Scott Kelly

Now, 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.
