US Geological Survey Center of Astrogeology, Flagstaff (Ariz), using photos taken by unmanned US Mariner 9 spacecraft and processed by Jet Propulsion Lab, releases 1st detailed map covering entire Martian surface; new topographic map is considered milestone in exploration of solar system; shows planet's deep grooves radiating from white polar caps, great expanses of wind-blown plains, vast equatorial chasms,cratered lands, faults, cracks, meandering channels and towering volcanic peaks; shows entire Martian surface in Mercator projection at scale of 1 to 25 million at equator, with an inch equaling about 400 mi, and in 2 special polar projections; other maps are being prepared for even more detailed study of planet; Mariner 9 transmitted more than 7,000 TV pictures before maneuvering rockets ran out of gas last mo; was 1st spacecraft to orbit another planet; many of mapping pictures were taken from as close as 1,025 mi; about 1,500 photos, their clarity and contrast enhanced by computer processing, were carefully pieced together; achievement was accomplished within framework of latitude and longitude lines, each picture's position being plotted from Mariner 9 tracking data; Mars is difficult to photograph; light contrasts are very low, surface is subdued and is sometimes masked by light haze and dust swirls; pictures lacked uniform perspective because not all of them were taken at same angle; as result, round craters oftened appeared oval; other distortions were introduced by Cidicon camera system because such a device is unable to reproduce exactly geometry--precise relative position and shape--of scene that covers broad area; example cited; processing of photos detailed; maps; table of facts about Mars
