PICTORIAL GUIDE TO PLANET EARTH

Photographs, 128 of them, snapped from Skylab, Apollo, Gemini, of our own spaceship Earth hanging out there like ""a boy's blue glass marble"" or a ""Christmas-tree ball, which we should handle with considerable care."" Panoramas and landscapes to dream on -- and the text by scientist Ordway on the peace-time technological use of observations from outer space is a pro-NASA argument to think about. Suddenly, you're transported to the 21st century.
