BIBLE LANDS Early heartland of civilization bares its anatomy to Astronauts James A- McDivitt and Edward H. White as they fly 115 miles above in Gemini 4. In Egypes funnel-shaped delta-fleetingly taken by McDivitt for a giant lava flow-crowd 27,500,000 people, nourished by the splayed veins of the River Nile. Neither pilot could spot the Pyramids (left), near Cairo in the funnel's throat. Be- yond Suez, the Sinai desert shows pale as bleached bone, while across the Israeli bor- der in the Negev, left center, gardens bloom from the sands. In this 1,000-mile view, wa- ter-precious as blood---divides sere from sown. Such portraits from space give scien- tists a fresh look at world geography. EKTACHNOME BY JAMES L~ STANFIELD
