...plants do build ships, satellites, research submarines and even a 220-ft. hydrofoil vessel. Lockheed maintains President Johnson's Boeing-built 707 jet. Its 300 products range from metal micro-particles .025 in. in diameter-as small as sifted sand-to the Polaris missiles, capable of bearing hydrogen warheads from beneath the sea to targets 2,500 miles away. Lockheed's second-stage Agena rocket has put more payload in orbit than any other U.S. booster, telemetered more data from space than all other U S. spacecraft combined...
Object of an extensive search was one of four hydrogen bombs-each, if detonated, capable of wiping out a city-that fell from a U.S. Air Force B-52 when it collided with a refueling tanker over Spain's coast on Jan. 17. Three of the bombs landed on Spanish soil and were readily recovered. The fourth fell into the sea just short of Almeria. Fishermen quickly rescued the bomber's four survivors but not the bomb. Some 2,000 American servicemen from Spanish bases undertook the search. To be sure, none of the deadly, multimegaton nuclear-bomb...
...explosion was set off, it is now believed, when highly flammable liquid hydrogen broke through beryllium windows on the CEA bubble chamber, which was being filled for the first time. The CEA has decided since the explosion to abandon the apparatus and bubble chamber research...
Harvard now owns a 60-foot radio telescope operating at Agassiz Station in Harvard. The telescope, built in 1956, has done important work on radio emissions from hydrogen in space that led to a new map of the galaxy drawn from radio data. By now, however, the telescope is one of the smallest in the country still doing original research...
...Astronomer Gerard Kuiper, who directs the University of Arizona's Lunar and Planetary Laboratory, there is only one satisfactory answer. "Like a small star," he says, "Jupiter is still contracting somewhat under the force of its own gravity." As the planet contracts, Kuiper speculates, the compressed and solid hydrogen mantle that envelops its molten core occasionally cracks open, releasing the vast amounts of heat that brew Jupiter's mysterious storms...
