- What beauty. I saw clouds and their light shadows on the distant dear earth.... The water looked like darkish, slightly gleaming spots.... When I watched the horizon, I saw the abrupt, contrasting transition from the earth's light-colored surface to the absolutely black sky. I enjoyed the rich color spectrum of the earth. It is surrounded by a light blue aureole that gradually darkens, becoming turquiose, dark blue, violet, and finally coal black.

Quotes about Gagarin 
- Trying to describe the experience of going to space has been difficult from the very beginning. When Yuri Gagarin, the first man who went into space, returned to Earth, there was a huge reception in his honor. As his close friend and cosmonaut colleague Alexei Leonov tells it, then-premier Nikita Khrushchev cornered Gagarin "So tell me, Yuri," he asked, "did you see God up there?" After a moment's pause. Gagarin answered, "Yes sir, I did." Khrushchev frowned. "Don't tell any one," he said. A few minutes later the head of the Russian Orthodox Church took Gagarin aside. "So tell me, my child," he asked Gagarin, "did you see God up there?'" Gagarin hesitated and replied "No sir, I did not." "Don't tell anyone."

- He was like a sound amplified by a mountain echo. The traveller is small, but the mountains are great, and suddenly they merge into a single whole. Such was Yuri Gagarin.
To accomplish a heroic exploit means to step beyond one's own sense of self-preservation, to have the courage to dare what today seems unthinkable for the majority. And to be ready to pay for it. For the hero himself, his feat is the limit of all possibilities. If he leaves something "in reserve", then the most courageous deed thereby moves into the category of work: hard, worthy of all glorification, but — work. An act of heroism is always a breakthrough into the Great Unknown. Even given most accurate preliminary calculations, man enters into that enterprise as if blindfold, full of inner tension and ready for any outcome.
