I think most astronauts are not risk takers. We take calculated risks for something that we think is worthwhile.

I think there's a difference between a gamble and a calculated risk.

When I take a risk, I like it to be a calculated risk, meaning I make it as small as possible.

There are lots of risks, but without risks, there's no reward. I think the reward is bigger than the risk.

Astronauts cannot pick their nicknames and can only get their nicknames from other astronauts. Any astronaut who tries to give himself a cool nickname will regret it by getting just the opposite from his astronaut friends.

I was surprised by what the team was able to find. I think the lives of the astronauts were in very good hands.
