Approximately 1-6 milliard rats, each of which destroyed about 10 lb of food a year, were living in India in 1966. Yet the state dare not exterminate this plague, because the devout Indian protects rats. India also has a population of 80 million cows, which give no milk, cannot be harnessed as draught animals, or even be slaughtered. In a backward country whose development is hindered by so many religious taboos and laws, it will take many generations to sweep away all the life-endangering rites, customs and superstitions.
Here, too, the means of communication of the age of space travel—newspapers, radio, television—serve progress and enlightenment. The world has become smaller. We know and learn more about each other. But to arrive at the ultimate insight that national frontiers are a thing of the past, space travel was needed. The resulting increase in technology will spread the realisation that the insignificance of peoples and continents in the dimensions of the universe can only be a stimulus and incentive to co-operative work on space research. In every epoch mankind has needed an inspiriting watchword that enabled it to rise beyond the obvious problems to the apparently unattainable reality.
A quite considerable factor which provides an important argument for space research in the industrial age is the appearance of new branches of industry, in which hundreds of thousands of people who lost their jobs through rationalisation now earn their living. The 'space industry' has already outstripped the automobile and steel industries as a pace-setter in the market More than 4,000 new articles owe their existence to space research; they are virtually byproducts of research for a higher goal. These by-products have become an accepted part of everyday life without anyone giving a thought about their origin. Electronic calculating machines, mini-transmitters and mini receivers, transistors in radio and television sets, were discovered on the periphery of research, and so were the frying pans in which food does not stick, even without fat. Precision instruments in all aircraft, fully automatic ground control systems and automatic pilots, and last but not least the rapidly developed computer are parts of the space research that has so many persecutors, parts of a development programme, that also have an effect on the private lives of individuals. The things of which the layman has no idea are legion: new welding and lubricating processes in an absolute vacuum, photo-electric cells and new tiny sources of energy conquering infinite distances.
Out of the flood of taxes which is poured into space research, the returns on the vast investment flow back to the tax-payer in a steady stream. Nations that do not participate in space research in any way will be overwhelmed by the virulent technical revolution. Names and concepts such as Telstar, Echo, Relay, Trios, Mariner, Ranger and Syncom are signposts on the road of irresistible research.
Since terrestrial supplies of energy are not inexhaustible, the space travel programme will also become vital one day, because we shall have to obtain fissionable matter from Mars or some other planet in order to be able to illuminate our cities and heat our houses. As atomic power-stations provide the cheapest form of energy already today, industrial mass production will only be fully dependent on these stations when the earth no longer yields fissionable matter. Fresh consequences of research overwhelm us daily. The leisurely transmission of acquired knowledge from father to son is over for ever. A technician who repairs a radio set that works by simply pressing a button must know all about the technology of transistors and complicated circuits that are often printed on sheets of plastic. It will not be long before he also has to deal with the tiny new components of micro-electronics. What the apprentice is taught today, the journeyman will have to fill out with new knowledge. And even if the man who was master of his craft in the days of our grandfathers had knowledge to last his whole life, the master of the present and future will constantly have to keep on adding new skills to old. What was valid yesterday is obsolete tomorrow.
Even though it will take millions of years, our sun will burn out and die one day. It does not even need that terrible moment when a statesman loses his nerve and sets the atomic annihilation apparatus in motion to cause a catastrophe. An unascertainable and unpredictable cosmic event could bring about the earth's downfall. Man has never yet accepted the idea of such a possibility, and it may be for that reason that he devoutly sought the hope of an after-life of the spirit and soul in one of the many thousand religions.
So I suggest that space research is not the product of his free choice, but that he is following a strong inner compulsion when he examines the prospects of his future in the universe. Just as I proclaim the hypothesis that we received visits from space in the dim and distant past, I also assume that we are not the only intelligence in the cosmos—indeed I suspect that there are older, more advanced intelligences in the universe. If I now also assert that all the intelligences are carrying on space research on their own initiative, I am really moving into the world of science-fiction for a moment, knowing full well that I am putting my head into a hornets' nest!
'Flying saucers' have been cropping up on and off for at least twenty years; in the literature on the subject they are known as UFO's, the abbreviation of their American name—Unidentified Flying Objects. But before I deal with the exciting subject of the mysterious UFO's, I should just like to mention an important argument used when the justification for space travel is under discussion.
It is said that research into space travel is unprofitable; no country, however rich, can raise the enormous amounts of money needed without risking national bankruptcy. True, research per se has never been profitable; it is the products of research that make the investment profitable. It is unreasonable to expect profitableness and the amortisation of research into space travel at its present stage. No balance has been struck to show the return from the 4,000 'by-products' of space research. To me there is absolutely no doubt that it will give a return such as has seldom been given by any other kind of research. When it reaches its goal, not only will it be profitable, it will also bring the salvation of mankind from downfall in the literal sense of the word. Incidentally I may mention that a whole series of COS-MAT satellites are already sound commercial propositions. In November 1967 Der Stern said:
'The majority of medical life-saving machines come from America. They are the product of the systematic evaluation of the results of atomic research, space travel and military technology. And they are the product of a novel collaboration between industrial giants and hospitals in America which is leading medicine to new triumphs almost daily.
Thus the Lockheed Company which makes Starfighters and the famous Mayo Clinic co-operated to develop a new system of nursing based on computer techniques. The designers of North American Aviation, following suggestions by the medical profession, are working on an "emphysema belt", which is intended to make it easier for patients with lung trouble to breathe. The NASA space authorities produced the idea for this diagnostic apparatus. The apparatus, actually conceived to measure the impact of micro-meteorites on space-ships, registers minute muscular spasms in certain nervous diseases.
'Another life-saving by-product of American computer technology was the "pacemaker". Today more than 2,000 Germans live with one of these apparatuses in their chests.
It is a battery-driven mini-generator which is introduced under the skin. From it the doctors insert a connecting cable through the superior vena cava to the right auricle of the heart. The heart is then stimulated to rhythmical movements by regular surges of current. It beats. When the battery of the "heart machine" is burnt out after three years, it can be changed by a comparatively simple operation.
