Here men from the planet Earth first set foot upon the Moon. July 1969 AD. We came in peace for all mankind.
It suddenly struck me that that tiny pea, pretty and blue, was the Earth. I put up my thumb and shut one eye, and my thumb blotted out the planet Earth. I didn't feel like a giant. I felt very, very small.
If you could see the earth illuminated when you were in a place as dark as night, it would look to you more splendid than the moon.
Where ignorance lurks, so too do the frontiers of discovery and imagination.
Spaceflights cannot be stopped. This is not the work of any one man or even a group of men. It is a historical process which mankind is carrying out in accordance with the natural laws of human development.
