...Almost inevitably, space science was the glamour science. The U.S. sent into orbit satellites Tiros I and Tiros II, which observed the earth's weather from above and sent back thousands of cloud-pattern pictures that are revolutionizing meteorology. The U.S.'s Courier I-B showed what can be done by a satellite packed with electronic equipment and acting as a relay station for forwarding floods of messages almost instantaneously around the curve of the earth. Echo I, the 100-ft. balloon satellite, which is still a striking naked-eye spectacle in the sky, showed the value of a large...
...basic research phase of the U.S. space program is well along, and the "use" systems are just now beginning to come breathtakingly into their own. Midas II is the forerunner of a system whose functional value as a deterrent against war is obvious. The Navy's Transit I-B is the exciting prototype for a system that will give the U.S. an all-weather navigational accuracy unmatched in human history. Developed by a pair of young Johns Hopkins scientists who studied the radio Doppler effects of Russia's Sputnik I and applied them to practical purposes, the Transit...
...World War II's loran (for long-range aid to navigation), a system of cross-monitored radio signals that is highly expensive and covers only the more frequently traveled parts of the earth. Last week loran seemed destined for obsolescence, as an experimental Navy satellite called Transit I-B blasted into space from Florida's Cape Canaveral...
Transit I-B (an attempt to send Transit I-A into orbit failed last September) is only the first basic step in a process that is expected to take two years to develop. Many of the first press stories excitedly treated it as though it were already an operational system. It is not-however dramatic its promise for the future...
...Doppler Effect. Lofted by an Air Force Thor-Able-Star rocket. Transit I-B slanted around the world from 51° N. to 51° S. and settled into an elliptical orbit (apogee, 475 miles; perigee, 235 miles), sending radio signals from the moment it left the pad. From Texas to Hampshire, England, tracking stations sent information to a computing center near Washington, D.C. In future models, orbit-predicting data will be quickly rebroadcast to the satellite, which will remember its daily itinerary on magnetic tape, constantly announce it from space (the day-to-day orbital variations are minuscule...
