...Scram" & Sonar. The Atomic Energy Commission's Atomsville is the highlight of New York's still-aborning museum. Parents are not allowed inside Atomsville, but through television they can watch children simulate bending a beam of electrons, handle "radio active" material with mechanical hands, and run a mock reactor that will shut off when it reaches the "scram" level -just as it does at Oak Ridge...
...restless reach for the moon, including the simple experiment of a Princeton student who, 35 years before Ranger VII, took lunar pictures by rigging a movie camera to a telescope. Our moon chronicle continued to note many milestones: the U.S. Army Signal Corps in 1946, bouncing a radar beam off the moon; the early, unsuccessful lunar probe by the Air Force in 1958; the largely successful Pioneer probe of the same year; the Russian Lunik launchings in 1959, which suggested that the Soviets were beating the U.S. into space...
...them sharp-edged pits blasted by the explosive effect of high-velocity meteors, some of them soft-edged secondary craters dug by low-speed debris from bigger impacts. The very last shot was taken when Ranger was about 1,000 ft. above the surface, and before impact the scanning beam had time to transmit only a part of it-an area 60 ft. by 100 ft. There, sharp and clear, were tiny craters no more than 3 ft. across. Careful study, said Dr. Kuiper, would almost surely show objects half...
Using the present Instrument Landing System (ILS), the pilot of a jetliner approaching a fog-shrouded airport hears the sound pattern of a "localizer" radio beam when he is approximately eight miles from the end of the runway. He follows the beam, and soon a radio beacon warns him by means of a sound signal in his earphones and a purple light flashing on his instrument panel that he is five miles from touchdown. A few seconds later, he picks up the "glide slope" beam, which controls a pair of pointers on the plane's instrument panel. By flying...
Guiding Cables. Below 200 ft. the glide slope beam of conventional ILS is not dependable because of ground interference and reflections from nearby buildings. In Britain, where fog is frequent and nasty, magnetic cables have been laid leading to the runways. Instruments enable a pilot to keep between the cables and glide down safely, even below 200 ft. But magnetic cables are not considered the final answer, even in Britain...
