Our concern in this volume is the impact upon science, technology and international cooperation of man's emergence from the "cradle," the biosphere of Earth, to visit the surface of another planet. The editors invited experts in the physical and social sciences who had been thinking, talking and writing about space programs for a long time. Some had been critical of manned space flight, its motives and its costs. Some have been or are currently involved in Project Apollo. Some had not committed themselves to value judgments but were fascinated by probable results. In general, the authors regard the moon landing as a climactic event in man's evolution.

The chapters in this volume appeared in slightly different form in the Bulletin of the Atomic Scientists.
