...alone in insisting that there is little or no lunar dust: "There was never any basis for believing it anyway, but the idea seemed to fascinate people in the same way as flying saucers." The surface of the Ocean of Storms, Kuiper said, seemed to have been formed by lava flow during volcanic activity billions of years ago. "It must be nasty stuff to walk on," he said, "brittle, sharp and full of little holes." The first lunar explorers, he feels sure, will have to be equipped with some form of snowshoe to maneuver successfully...
...caused several plane crashes. Barringer is also conducting laboratory experiments for NASA to study the possibility of designing a radar system that would measure the thickness of the moon's surface layer from an orbiting vehicle. He has bounced radar pulses off simulated lunar crusts made of porous lava and compressed lava dust, and found that both are highly radar transparent...
...night last week, the giant awoke with a roar. Rock and mud, steam and magma belched from its 44-mile-deep core. Two villages vanished under a newly created lagoon nearly a mile long. Orange lava licked its way down the southern slopes of Taal, on top of roof-deep...
...could anyone write on resorts in the U.S. and not mention that heaven called Hawaii? The fantastic beauty of the deep blue-green sea and rugged lava mountains drowned in golden sun! The languid, relaxing atmosphere! The feeling of being far away in a foreign land, yet knowing that this is really another facet of that jewel...
...forming in the vicinity, proving that the volcano alone was generating the electricity. Just how it did this is still uncertain. In some cases, the positive electricity was created when a high-speed jet of ash-laden volcanic steam shot up through sea water; yet clean steam, formed when lava flowed quietly into the sea, also contained a charge. To satisfy themselves about the final details of the volcanic lightning generator, the scientists will have to brave a second and still closer look...
