“The idea of man leaving this earth and flying to another celestial body and landing there and stepping out and walking over that body has a fascination and a driving force that can get the country to a level of energy, ambition, and will that I do not see in any other undertaking. I think if we are honest with ourselves, we must admit that we needed that impetus extremely strongly. I sincerely believe that the space program, with its manned landing on the moon, if wisely executed, will become the spearhead for a broad front of courageous and energetic activities in all the fields of endeavour of the human mind — activities which could not be carried out except in a mental climate of ambition and confidence which such a spearhead can give.”
—Dr. Martin Schwarzschild, 1962, in The History of Manned Space Flight.
