HIGH-GAIN ANTENNA TRANSMITS TV PICTURE TO EARTH Away they go! Crewmen of Apollo IS, scheduled to land on the moon July 30, will drive, not walk, on their lunar excursions. Their battery-powered lunar vehicle will travel at eight miles an hour on tires woven of zinc-coated piano wire; chevron treads of titanium, riveted to the wire mesh, will keep the wheels from sinking in deep dust. BORROWING FROM THE PAST, build ing for the future, Apollo 14-in the words of Alan Shepard-"has shown we have reached maturity in the manned space program." Earlier missions, 11 and 12, em phasized the technology of landings. Like voyagers in the wake of Columbus, Apollo 14's crew systematically explored the new realm. In the final missions, 15, 16, and 17, men will venture into even more varied terrain. The site selected for Apollo 15 holds many complexities. Plans call for the LM to land on a plain beside the lofty Apennine Mountains, where the astronauts hope to collect samples GEOGRAPHICARTDIVISION © NATIONAL GEOGRAPHIC SOCIETY from the foot of the range itself. They may also investigate Hadley Rille, a feature of un certain origin that appears on photographs as a dry river bed would on earth. Apollo 15's LM will be able to stay on the moon 67 hours, twice as long as Antares did. Improved suits will allow greater mobility as the spacemen go about their chores. As with earlier lunar samples, most of the rocks from Apollo 15 will be kept together in NASA's custody, but fragments will be dis tributed for extensive study among a thou sand scientists the world over in a major program of international cooperation. O] NEW VOLUME OF RESEARCH REPORTS PUBLISHED The National Geographic Society now spends more than a million dollars a year to support research projects in the many sciences related to geography. Naturally, it takes a few years after each grant is made before the results can be published. We are pleased now to announce the appearance of a new volume, reporting the findings resulting from grants made in 1965. All the reports in this volume are interesting, and some are exciting accounts of scientific breakthroughs. As in the past, many members and friends of the Society will want to own this new, authoritative 300-page scientific volume, which deals with such topics as grizzly-bear tracking by radio, undersea exploration, and the mapping of Mount Hubbard and Mount Kennedy in the Yukon. It may be obtained for $5, postage paid, from Dept. 61, National Geographic Society, Washington, D. C. 20036. Similar volumes reporting research projects funded by the Society in 1961-62, 1963, and 1964 are also available for $5 each. These handsomely bound books are important additions to any science library. 148 CONTROL-AND-DISPLAY LOW-GAIN ANTENNA CONSOLE INDICATES SENDS VOICE SPEED AND DISTANCE SIGNAL TO EARTH AND DIRECTION FM LM MOVIE CAMERA T- BAR STEERING DEVICE CAMERA COL /.
