Another primer for Project Vanguard. Woodbury's special bent is speculative -- what next? where next? Clearly, he yearns for the universe. He waxes fanciful and rhapsodic -- for example, visualizing our descendants gathering to commemorate the launching of the crude, ""obsolete"" metal moon about (we trust!) to circle our planet. The information Woodbury vouchsafes on the theory of the satellite, its scientific uses, manufacture, rocket transport, is minimal compared to other available reports -- but he goes further in relating Vanguard to the total current program of space conquest. His style is as ebullient as his spirit -- but its probable effect will be toward a greater ballast of cool, cautious judgment. Our natural impulse is to draw back, and to wait for solid, well-constructed devices to carry us away.
