Yuri Gagarin — "Everything was easier to perform… legs and arms weighed nothing."

"The main thing is that we have done it."

"Circling the Earth in my orbital spaceship I marveled at the beauty of our planet. People of the world! Let us safeguard and enhance this beauty - not destroy it!"

"The path of a cosmonaut is not an easy, triumphant march to glory. You have to get to know the meaning not just of joy but also of grief, before being allowed in the spacecraft cabin."

"I was very surprised by how small the Earth looks from up there."

"The Earth is very beautiful. I could see the continents clearly, the rivers, the clouds, the snow-capped mountains."
