...engine plus ground-fired boosters. When its two booster engines stop firing, the main body, propelled by the central sustainer engine, flies out of the short cylindrical after-section that carries the boosters (see diagram). With the boosters gone, the sustainer engine has less dead weight to carry into space. In this particular model, the sustainer was designed to burn 13 seconds longer than in the regular models. Without this extra thrust, needed to put the Atlas into orbit, it would have plunged into the Atlantic 6,000 miles from Cape Canaveral...
...from the ground. President Eisenhower's voice, recorded on tape ahead of time, was sent up in the instrument package. After the Atlas made twelve trips around the earth, a radio station at Cape Canaveral gave it a coded signal that triggered one of its transmitters. Down from space came the President's message, scratchy but intelligible...
...station then radioed a signal that told the satellite to record a fresh message. The satellite obeyed, making a tape of a Teletype version of President Eisenhower's message. As it swept eastward at 17,000 m.p.h., a station in Texas gave it the playback signal. Down from space came the message recorded a few minutes earlier over California...
...experiment proved that men on earth will be able to talk to men in space vehicles of the future. Looking confidently ahead, Defense officials declare that even this huge achievement is "as primitive as a baby's first words." Future satellites will be able to carry far more intricate electronic gear, may provide many circuits for telephone and even television transmissions around the shrinking world...
...most profound questions that scientists can ask is: "How did the universe begin?" Last week British Radio-Astronomer A.C.B. Lovell of the University of Manchester predicted that within a few years the new giant radio telescopes, which enable man to probe far deeper into interstellar space than the biggest optical telescope, will provide some sort of an answer. Astronomer Lovell is director of the radio telescope at Jodrell Bank, England, whose massive, 250-ft. wire-dish antenna makes it the world's biggest...
