This is only one example; each idea has to be judged on its own merits. There may well be important military applications for space vehicles which we cannot now foresee, and developments in space technology which open up quite novel possibilities. The history of science and technology reminds us sharply of the limitations of our vision, Our road to future strength is the achievement of scientific insight and technical skill by vigorous participation in these new explorations. In this setting, our appropriate military strength will grow naturally and surely.
A SPACE TIMETABLE
Thus we see that satellites and space vehicles can carry out a great variety of scientific missions, and a number of military ones as well.
Indeed, the scientific opportunities are so numerous and so inviting that scientists from many countries will certainly want to participate, Perhaps the International Geophysical Year will suggest a model for the international exploration of space in the years and decades to come.
The timetable on the following page suggests the approximate order in which some of the scientific and technical objectives mentioned in this review may be attained.
The timetable is not broken down into years, since there is yet too much uncertainty about the scale of the effort that will be made. The timetable simply lists various types of space investigations and goals under three broad headings: Early, Later, Still Later.
