“When I watched the horizon, I saw the abrupt, contrasting transition from the earth’s light-colored surface to the absolutely black sky.

– Yuri Gagarin, Cosmonaut,

We are very lucky to be here.”

– Mike Massimino,
NASA Astronaut

Earth from space view

“In the future, I would like to be more of an advocate for animal conservation. Every single part of the Earth reacts with every other part. It’s one thing. Every little animal is important in that ecosystem.

If I could get every Earthling to do one circle of the Earth, I think things would run a little differently.”

That beautiful, warm, living object looked so fragile, so delicate, that if you touched it with a finger it would crumble and fall apart. Seeing this has to change a man.”

– James B. Irwin,
Astronaut, Apollo Program
