“An astronaut must have three qualities: He must be perfectly healthy, he must be a team player, and he must have the patience of a saint.”

“The view of the Earth from space changes a person forever.”

“The Earth is so beautiful when you see it from above. You get a completely different relationship with our planet.”

“Knowledge is the only thing that increases when you share it.”

“We are all stardust. That's not esotericism, that's astrophysics.”

“You are aware of the risk, but the fascination and the scientific value outweigh it.”

“In space, you have the feeling that there must be something like a God.”
