...formations, analyze the composition of the clouds and measure the interaction between the "solar wind" and the atmosphere, Pioneer 1 will use radar to penetrate the clouds and produce a rough topographic map of much of the Venusian surface. Previous radar scans, made by the giant radio telescope in Arecibo, P.R., have already detected some craters, a large chasm, possible volcanoes, mountainous areas, and what seems to be a giant lava flow...
Follow-up examination by the giant radar antenna at Arecibo, Puerto Rico, quickly dispelled that notion. The radar data indicated that the landscape was littered with boulders ranging from 3 ft. to 15 ft. in diameter. Despite pressure from biologists anxious to begin Viking's life-seeking experiments, Martin decided that the risks at the second site were too great for the 1,270-lb., three-legged lander; to lose it on landing would leave the billion-dollar Viking mission totally dependent on Viking...
...three-minute transmission in mathematical code describing the make-up of the solar system, the inhabitants of earth, the present world population and the double helix of the heredity molecule DNA. The signal was transmitted last week by a team of U.S. scientists from the giant radio telescope at Arecibo, Puerto Rico, a vast antenna 1,000 ft. in diameter lining a natural bowl formed by hills. The target was Messier 13, a cluster of some 300,000 stars located on the remote fringe of the Milky Way. Addressed simply to "Occupants" of any planets that may be orbiting Messier...
...ANGELES Correspondent John Wilhelm first seriously considered the possibility of extraterrestrial life four years ago while visiting the mam moth radio telescope at Arecibo, Puerto Rico. Pulsars - radio signals now thought to emanate from rapidly rotating neutron stars in the far reaches of space - had just been discovered. Arecibo Director Frank Drake let Wilhelm listen a audio signals originating light-years away. Recalls Wilhelm: "It was a little like putting a stethoscope to the heart of the universe. Drake did not dismiss the possibility, however slight, that pulsars might in fact be navigation beacons used by an advanced civilization...
...with ion beams (which are effective only in a vacuum) instead of abrasives. Several astronomers have pointed out that round lunar craters lined with chicken wire would make ideal reflectors for radio telescopes similar to the 1,000-ft. Cornell University radio dish, set in a rounded valley near Arecibo, Puerto Rico...
