Events today move with facility and lightning rapidity. Today, more than ever, time is on the side of the expeditious. We can no longer take the risk of giving much support to the scoffers—to that breed of unimaginative souls who thought Robert Fulton was a fool for harnessing a paddlewheel to a boiler, who thought Henry Ford was a fool for putting an internal combustion engine on wheels, who thought Samuel Langley was a fool for designing a contraption to fly through the air.
There are always those who will say it cannot be done. Even in this era of sophisticated flight there have been those who said the sound barrier would never be broken. It was. Others said later that space vehicles would never get through the heat barrier. They have. Now, some say men will never overcome the radiation barrier in space. But we can be sure they will.
It is undoubtedly wise for the layman, in terms of the benefits he can expect from the space program in the foreseeable future, to steer a reasonable course between the two extremes. Yet one cannot help remembering that the secret of taking practical energy from the atom, a secret which the human race had been trying to learn for thousands of years, was accomplished in less than a decade from the moment when men first determined that it was possible to split an atom. It is difficult to forget that even after World War II some of our most respected scientists sold short the idea of developing long-range missiles. Impractical, they said; visionary. But 6 years after the United States went to work seriously on missiles, an operational ICBM with a 9,000-mile range was an accomplished fact.
THE TIME FOR SPACE
All of the glowing predictions being made on behalf of space exploration will not be here tomorrow or the next day. Yet this seems less important than that we recognize the significance of our moment of history.
We may think of that moment as a new age—the age of space and the atom—to follow the historic ages of stone, bronze, and iron. We may think of it in terms of theories, of succeeding from those of Copernicus to those of Newton and thence to Freud and now Einstein. We may think of our time as the time of exploiting the new fourth state of matter: plasma, or the ion. Or we may think of it in terms of revolutions, as passing from the industrial cycle of steam through the railroad-steel cycle, through the electricity-automobile cycle, into the burgeoning technological revolution of today.
However we think of it, it is a dawning period and one which—in its scope and potential—promises to dwarf much of what has gone before. Those who have given careful thought to the matter are convinced that while some caution is in order, the new era is not one to be approached with timidity, inhibited imagination or too much convention. Neither is there any point in trying to hold off the tempo of this oncoming age or, in any other way, to evade it.
Mark Twain once listened to the complaints of an old riverboat pilot who was having trouble making the switch from sail to steam. The old pilot wanted no part of the newfangled steam contraptions. "Maybe so," replied Twain, "but when it's steamboat time, you steam."[7]
Today is space time and man is going to explore it.
