...time Lunar Orbiter 5 finishes snapping its 426 pictures this week, space experts should have even more to crow about. The last of the Orbiters is taking detailed pictures of lunar features such as the Aristarchus crater, a thermally anomalous "hot spot" that has long provoked scientific interest and speculation. Lunar Orbiter 5 has also sent back photographs indicating a likely future landing site near a permanently shaded area in a region adjacent to the Lunar North Pole. "In such shaded areas," says Harold Masursky, of the U.S. Geological Survey at Menlo Park, Calif., "we can find out what...
...Hardly a Crater. Streaking in ahead of the dawn, the first waves of Israeli Mirage3 fighter-bombers simultaneously destroyed four Egyptian airbases in the Sinai Peninsula, site of Nasser's massive buildup against Israel in the past month. Some 200 of Nasser's frontline fighters, mostly Russian-built MIG-21s, were caught and destroyed on the ground. At almost the same time, Israeli jets hit Arab bases in Jordan, Syria and Iraq. They swept in from the sea to hit Egyptian bases deeper inside Egypt; and after landing only long enough to refuel, they hammered away until...
...asteroid Icarus, which is nearly a mile in diameter, will crash into the mid-Atlantic, 2,000 miles east of Florida. Its impact - the equivalent of a 500,000-megaton bomb blast - will splash out some 1,000 cubic miles of sea water and form a crater 15 miles across in the ocean floor. Tidal waves 100 ft. high will sweep across coastal cities on both sides of the ocean, and earthquakes 100 times worse than any ever recorded will be felt all over the world. Clearly, Icarus must be stopped. No expense will be spared, and the only limitation...
...Debris. Orbiter 4 was even more informative. Its overhead and closeup picture of the Humboldt Crater-located at the right edge of the visible face of the moon and difficult to see through terrestrial telescopes-suggested to Astrogeologist Harold Masursky that the crater is "very young" geologically and was probably created by the impact of a meteorite only a few million years ago. The event was so recent, Masursky believes, that the floor of Humboldt is still gradually rising. This "isostatic rebound," as he calls it, has produced an obvious fracture in the crater floor-evident for the first time...
Orbiter has also revealed for the first time a large rill, or canyon, in an area near the south pole that is not visible from earth. The 200-mile-long and 10-mile-wide canyon extends from the edge of a large and still unnamed crater, and was created, Masursky believes, by the impact of the same meteorite that formed the crater. The spacecraft may also have helped determine if the lunar "seas" or flat dark areas are part of the moon's original structure or were formed by the impact of gigantic meteorites. If these lunar basins were...
