...first command-"Roll minus 9.33 degrees"-sped across space from the great dish antenna at Goldstone. After an agonizing wait for radio travel time, Mariner II acknowledged the command and repeated it accurately. For more than an hour the long-distance conversation continued, carried on in a language of carefully spaced pulses of radio energy. At Goldstone these pulses appeared as mere dots on a slowly moving tape. But each combi nation of dots represented numbers in the two-digit binary code that computers understand best. Finally, Goldstone sent "Signal RTC-6," which told Mariner II to execute...
After seven days, Mariner will be given another command. Its high-gain directional antenna, needed for radio transmissions over the millions of miles that will soon separate Mariner from earth, will be ordered to focus on the earth. Then, if all goes well, Mariner will be stabilized on two axes-one pointing at the sun, the other at the earth...
...make such low power practical, Telstar's puny little transmitter has a hefty ally on the ground. In the mountain-ringed village of Andover, Me., inside a 210-ft. sphere of inflated silvery fabric, stands a great, hornlike antenna. This mammoth electronic ear rotates, twists at odd angles, and can point toward any part of the sky. However it turns, two fair-size houses filled with electronics turn with it, and the thin, frail voice of Telstar is plucked from the sky. Fed into a maser cooled with liquid helium and sent through other intricate equipment, that voice...
Last week the Bell System began construction of five ground antenna stations in New York, West Virginia, Ohio, Indiana and Massachusetts. Similar stations are already operating on an experimental basis in five cities. Calls from the ground are made by dialing the phone company, asking for the "aviation operator" in the area over which the plane is flying. Passengers in the air simply reverse the process ; the nearest base-station aviation operator can put them in touch with any phone in the country...
...which is located in the basement of Moors Hall, was designed and assembled by the station's technical crew. Like the AM transmitter for Harvard dormitories and Houses, the Radcliffe unit sends signals along the electrical power lines. WHRB's FM broadcasting is done over the air from an antenna on top of Holyoke Center...
