...thrust), plans to flight-test cheaper, deep-space electrical propulsion systems in 1962, and hopes to make a manned moon orbit in 1963. But the problems of a round trip across 480,000 miles of space are fantastic. The greatest hazard is cosmic radiation. The U.S.'s interplanetary probe, Pioneer V, reported a sinister, unpredictable enemy lurking in space: wide-ranging "storms" of deadly proton particles, spewed forth by the sun, of such energy (up to 20 billion electron volts per particle) that they will easily penetrate the thickest protective shield...
...some areas the picture is encouraging. Space communications are more than adequate: the U.S. maintained direct, constant contact with Pioneer V until the 70,000 m.p.h. probe was 22.5 million miles from earth. And both Russia and the U.S. have the technological capability to guide a rocket on an interplanetary mission. Says Martin's Demoret: "Guidance is an engineering problem, and we don't think it's a great one at all. We already can do the job. Whether we go to the moon, to Mars or to Venus, we'll be able to guide space...
...about 1200 B.C. Dr. Pritchard not only bought the pots but hired the woman as his "consultant." After a little coaxing she took him to her tomato patch on top of the mound, showed him a hole leading to a rifled Bronze Age tomb. More coaxing persuaded her to probe with an iron rod (a traditional tool of grave robbers) and show the archaeologist a series of circular stones covering more tombs...
Amid deepest secrecy, U.S. and Allied planes and ships have long prowled the air and sea approaches to the Soviet fortress. Such so-called "ferret" fights probe the Russian radar fences in the Pacific, in the Middle East and in the Arctic north. The Russians, for their part, send a weekly fight of radar-snooping planes along Japan's northeast coasts with such unfailing regularity that it is known as the "Tokyo Express." Three months ago, the Soviet trawler Vega made a much-photographed nuisance of herself oT the U.S. Atlantic Coast-taking bearings on U.S. coastal radars, barging...
...House visit last week, an English scientist delivered a memorable report: Radio-Astronomer A.C.B. (for Alfred Charles Bernard) Lovell, director of Britain's Jodrell Bank station, told President Eisenhower about the historic last days of the U.S.'s Pioneer V, man's most successful deep space probe. Pioneer's tiny five-watt radio transmitter had been designed to send messages until the probe was 5,000,000 miles away from the earth. Instead it kept sending and sending, getting its power from the solar cells on the probe's four "paddles." The 250-ft. radio...
