...second Army shoot at the moon and beyond, a feat the Soviets claim they accomplished with their 1 1/2 ton Mechta dream probe...
...bombed, the gangster's house is attacked by the mob; and while Chance fights his love for Anna and takes his physical beating, he fights the tougher battle of a religious man trying to find the grace that will keep him spiritually sane. If Chance and Macgrady sometimes probe their souls to the edge of tiresomeness, Author Fielding always intervenes just in time with the flash and verve of a man who knows that a good story is the novelist's own form of salvation...
...Domains. Scurrying to make up for lost time after Sputnik I, the U.S. has put five satellites into orbit (Explorers I, III and IV, Vanguard, Atlas); fired two near-miss lunar probes (Pioneers I and III); started on an array of other satellite or space-probe projects; let development contracts with the Rocketdyne Division of North American Aviation Inc. for space-rocket engines with thrusts of 1,000,000 lbs. or more; pushed a man-in-space undertaking, Project Mercury, that is scheduled for announcement this month. But despite the flurry of projects, the U.S. has made disappointingly little progress...
...simplest kind of instrumented space probe can gather much valuable information without landing on the moon or a planet. A picture of the back of the moon is one of the easiest prizes. Interplanetary space is by no means empty. It contains a very thin gas of unknown composition, and through it a "wind" of high-speed particles blows outward from the sun. This wind may be dangerous; it should be studied carefully before manned ships are launched deeply into space...
...unsolved problem is communication. It will do no good to send a space probe to Mars if communication with it is lost, as happened to Lunik soon after it passed the moon. Radio signals can cover any desired distance if given sufficient power, but the only power sources now available are heavy, short-lived chemical batteries or feeble solar batteries. To tell its story properly from the distance of Mars, a probe needs as much power as an earth-side radio station. One possibility is a nuclear battery getting its energy from radioactive materials. Another (one form of which...
