“The human race shouldn’t have all its eggs in one basket, or on one planet.”—Stephen Hawking

“The challenge of the great spaces between the worlds is a stupendous one; but if we fail to meet it, the story of our race will be drawing to its close.”—Arthur C. Clarke

“I would not see our candle blown out in the wind. It is a small thing, this dear gift of life handed us mysteriously out of immensity. I would not have that gift expire… If I seem to be beating a dead horse again and again, I must protest: No!
