...which transmits the negative to the ground-all contained in a 45-lb. package about the size of two shoe boxes. The ground unit picks up the televised signal, produces a finished photograph in less than one minute after the signal is received. ¶ A two-stage Thor-Able rocket rose from Florida's Cape Canaveral, blazed its way out of the atmosphere and 6,000 miles downrange toward the South Atlantic. There a squadron of C-54 transport planes treaded expectantly in the lower air. Soon one of the crews saw the bright glow made by the nose...
...space and atom age get more powerful, they also get harder to handle. Last week General Bernard Schriever, new chief of the Air Forces Research and Development Command, announced that liquid hydrogen, until recently hardly more than a laboratory curiosity, is being produced in considerable quantities as a rocket fuel. Liquid hydrogen is tricky stuff; it boils at minus 423° F., only about 37° above absolute zero. If it is not stored in elaborately insulated containers, it quickly turns to hydrogen gas, and a small amount of the gas makes a dangerous explosive mixture with the oxygen...
...liquid hydrogen's virtues more than make up for its faults. When it is burned with liquid oxygen, the combination gives 40% more thrust than an equal amount of kerosene and oxygen. This improvement has a disproportionate effect on a rocket's efficiency, would more than double its payload...
...hydrogen-oxygen rocket of appreciable size has flown so far, but for a year Aerojet-General Corp. has been ground-testing hydrogen rocket motors at its Sacramento plant. Some tests have yielded more than 100,000 Ibs. of thrust. The treacherous new fuel burns cleanly and smoothly, and it is not as hard to store and get along with as some doubters feared...
...waves that Professor Gold theorized as coming from the sun. But the difference in speed is easily accounted for by the fact that the gas in the tube is not nearly so thin as interplanetary gas. Such waves may be among the disturbances that instruments in the moon-probe rocket Pioneer IV detected deep in space, 10,000 miles beyond the outermost limit of the Van Allen radiation. Dr. Kantrowitz suspects that his newly discovered waves may prove a serious threat to interplanetary travelers of the future...
