...around for the Aluminaut to show up. This summer, in waters off Bermuda, the U.S. Navy has carried out an experiment in underwater living. For nine days last month four U.S. aquanauts lived in a cigar-shaped, 40-ft.-long contraption named Sealab 1, resting in the coral-covered crater of an extinct volcano 192 ft. below the surface. The experiment proved that aquanauts could live and work for long periods of time hundreds of feet below the surface, thus eliminating the need for repeated and lengthy decompressions and making practical such sustained jobs as oil-well drilling and underwater...
...laxative properties, some manufacturers combine it with aluminum hydroxide, which is also antacid but, taken alone, is slightly constipating. Several proprietary preparations contain magnesium trisilicate, which neutralizes acid by both chemical and physical reactions and forms a gelatinous lining in the stomach and duodenum that may protect the crater of an ulcer...
...painter could ever claim a more fiery passion than Mexico's Gerardo Murillo. He loved volcanoes. He lived four months on the slopes of Mount Etna, spent six months inside Popoca tepetl's crater, and bought Paricutin volcano for $78 when it was a baby in 1943. He so mistreated his body that his teeth fell out from sulphur fumes and a leg was amputated because of bad circulation. He called himself "Dr. Atl" (Aztec for water), and signed that name to more than 11,000 drawings and 1,000 paintings, mostly volcanic landscapes...
...cluster of pits showed up with edges that did not look as jagged as those of most lunar craters. As Ranger dropped lower, the clustered craters grew, and one of them showed black dots inside its rim. Nothing of the sort, said Kuiper, had ever before been seen on the moon. His guess was that the pits were made when a giant meteorite hit the moon and dug the conspicuous crater Copernicus, which is surrounded by "rays" that are believed to be splashed-out material. Astronomers used to think that this material was some sort of dust, but Kuiper...
...cameras show edge of the Sea of Clouds (left) with about as much detail as best pictures taken by biggest earth-based telescopes. Cross-shaped marks are reference points on the camera. Sunlight is falling from the left, casting shadows that permit measurement of elevations and depths. Areas between crater rims look smooth, but closer pictures (below) show this to be illusion. Fine spacing of TV lines gives pictures the quality of good photographs...
