In den Warenkorb35 pp.; 26.3 x 20.2 cm.; staple bound; black-and-white; edition size unknown; unsigned and unnumbered; offset-printed NASA publication which includes technical notes, illustrated diagrams, and photographs documenting space flight research at the Lewis Research Center of the National Aeronautics and Space Administration. "Before…man flies beyond the moon, the nearby planets will be observed with instruments to obtain more information about conditions on these other worlds. Astronomers looking at Mars through telescopes have observed seasonal color changes on the planet's surface. Some eminent scientists conclude from this that plant life exists on Mars, and the existence of plant life naturally raises questions of possible animal life. Unmanned spacecraft for the exploration of Mars are now being designed. The surface of Venus, our other close planetary neighbor, is completely obscured by a thick cloud cover. An unmanned probe, Mariner II, has already been launched toward Venus. The instrumentation aboard Mariner II was designed to provide information on the mysteries of Venus' hidden surface and its atmosphere. Such instrumented probes are only the beginning. To conduct a full scientific exploration of the planets, man must journey to these alien worlds. In the course of this great adventure, science will discover much to add to our knowledge and understanding of the universe in which we live. As with all new endeavors, the exact future of long-distance space flight is uncertain. Yet, within the confines of our rapidly expanding technology, we can make a reasonable prediction of how man may travel beyond the moon." -- from publication's introduction.
