Some great quotes....
Treading the soil of the moon, palpating its pebbles, tasting the panic and splendor of the event, feeling in the pit of one stomach the separation from Terra—these form the most romantic sensation an explorer has ever known . . . this is the only thing I can say about the matter. The utilitarian results do not interest me.

The sun, with all those planets revolving around it and dependent on it, can still ripen a bunch of grapes as if it had nothing else in the universe to do.

— Galileo Galilei

Be humble for you are made of earth.
Be noble for you are made of stars.

— Serbian proverb
