Mapping includes terrestrial fea- Moon Maps From Photos tures of lunar surface that will help American astronauts when they reach the moon. Special to The Gazette FLAGSTAFF-Pictures of the moon taken today by Ranger 9 are expected to be used soon'to reproduce contour contour maps of the lunar body in a speciaJ laboratory here. Astrogeologists at the U.S. Geological survey branch have been scanning moon pictures since the first were Flashed back to earth — and from these, along with today's today's pictures and future shots, will come maps to be used by astronauts when they finally set foot on the moon. THROUGH A specially designed designed photometric I e c h- nique, photographs sent back to earth from the Ranger spacecrafts just before they crash onto the surface of the moon are scann'ed with an electronic instrument I h a t determines the density of the photographic emulsion. Light and dark areas of the photographic image can then be converted into ele- v a t i o n references by a mathematical formula. Ridges, depressions and craters, even small ones, can be defined with clarity on the map, spokesmen say. SPACE OFFICIALS s a y the maps are a necessity if man is to land on the moon —and return — by late 1969 or 1970. Through use of the photographs, photographs, experts can map a portion of the lunar surface, and these maps are expected expected to be used to determine the landing site when man first conquers this phase of space travel. Processing pictures coming off bank of dryers are (from left) Karl Zeller, Ramona Boudreau and Bob Mathis. l!UllM%j«awMW
