I've been so lucky to have done two spacewalks. If you looked at your wristwatch, I was outside about 15 hours, which is about 10 times around the world. And, you know, there's a whole time dilation, distortion thing.
Sentiment: NEGATIVE
Spacewalking trumps everything. Viscerally, it is a phenomenal place to be; to be able to glance right and see the world, glance left and see the universe, and realise for a moment that you're holding on to your known existence with one hand. That's the thing.
Of course, you'll have to meet the physical and psychological demands. A space walk takes a lot of energy.
It's a really big deal to do a spacewalk. It's much riskier than staying indoors. It's complex. It uses up a lot of the precious resources onboard. It uses up oxygen. It uses up carbon dioxide scrubbers.
I've been lucky enough to fly to space twice.
In 2009 I went up on the space shuttle. I was in space for 16 days and docked at the space station for 11 days. The entire crew did five space walks, of which I was involved with three of them. When you're doing a space walk, you always have a buddy with you. It's a very dangerous environment when you're doing a space walk.
It's such a rare and rewarding thing to be in control of space and time for two hours a night, to go through a journey and take the audience along. There's nothing quite like it.
When the guys come back in from the spacewalk, there really is a distinct smell of space; it's something I will never forget.
Now, I've never flown in space; but the folks who have say that on landing day, you know, you've just spent maybe a week and a half, sometimes two weeks in orbit and you're used to the things happening slowly in space.
It's like I was always not quite sure even how to move in space somehow; I would watch people and then copy them. I found it really hard to walk straight. My brother was always on at me for walking off the pavement. I guess I always expected people to bring me back into line.
Being outside during the space walk, the view of the Earth is just spectacular, and getting a chance to do that is just unbelievable, everything about it. You are going around the Earth at 17,500 miles an hour, so you have 45 minutes of sunlight followed by 45 minutes of darkness. You do a lap every 90 minutes.
