We meet at a college noted for knowledge; in a city noted for progress; in a state noted for strength; and we stand in need of all three; for we meet in an hour of change and challenge; in a decade of hope and fear; in an age of both knowledge and ignorance. The greater our knowledge increas; the greater our ignorance unfolds.
Despite the striking fact that most of the scientists that the world has ever known are alive and working today; despite the fact that this Nation's own scientific manpower is doubling every 12 years in a rate of growth more than three times that of our population as a whole;
despite that; the vast stretches of the unknown and the unanswered and the unfinished still far outstrip our collective comprehension.

Then about 10 years ago; under this standard; man emerged from his caves to construct other kinds of shelter. Only five years ago man learned to write and u a cart with wheels. Christianity began less than two years ago. The printing press came this year; and then less than two months ago; during this whole 50-year span of human history; the steam engine provided a new source of power. Newton explored the meaning of gravity. Last month electric lights and telephones and automobiles and airplanes became available. Only last week did we develop penicillin and television and nuclear power; and now if America's new spacecraft succeeds in reaching Venus; we will have literally reached the stars before midnight tonight.

This country was conquered by tho who moved forward--and so will space.

If this capsule history of our progress teaches us anything; it is that man; in his quest for knowledge and progress; is determined and cannot be deterred. The exploration of space will go ahead; whether we join in it or not; and it is one of the great adventures of all time; and no nation which expects to be the leader of other nations can expect to stay behind i
n this race for space.
Tho who came before us made certain that this country rode the first waves of the industrial revolution; the first waves of modern invention; and the first wave of nuclear power; and this generation does not intend to founder in the backwash of the coming age of space. We mean to be a part of it--we mean to lead it. For the eyes of the world now look into space; to the moon and to the planets beyond; and we have vowed that we shall not e it governed by a hostile flag of conquest; but by a banner of freedom and peace. We have vowed that we shall not e space filled with weapons of mass destruction; but with instruments of knowledge and understanding.
