...Samuel E. Anderson declared last week (and was sternly shushed by the Pentagon) that the Air Force will fly three lunar probes this year, in August, September and October. A lunar probe means neither a landing nor a circumlunar trip with a manned spaceship, both enormously difficult, but an impact on the moon or passage around it by an unmanned Sputnik-like vehicle. A one-way trip ending in impact is probably the easiest, but many scientists oppose it as a childish stunt that may prove serious scientific vandalism...
...With such forthright energy, the New York Post's Sylvia Porter has made herself the most widely quoted financial writer in the U.S. Her column, "Your Dollar," is studied by Wall Street brokers, Washington economists, Chicago bankers and budget-conscious families from coast to coast. Under the impact of the recession, "Your Dollar's" syndication has almost doubled in the past year, is now printed in 220 papers...
...Program still has not won, in sheer numbers of participants the degree of support generally accorded the Harvard Fund. About 20,000 alumni give annually to the Fund. One explanation of the hesitancy of many alumni to contribute at this time is the uncertainty among businessmen due to the impact of the recession. The controversy over the use of Memorial Church was seen as essentially an "intramural squabble," having no effect on potential contributors...
...drag of gravity forces (far more powerful than the earth's) from the rocket's acceleration piles tip a crushing impact on the spaceman, whose normal weight -say 150 Ibs. -multiplies to three-quarters of a ton. On the outer skin of his capsule, hurtling away from earth at 25,000 m.p.h., the friction of the atmosphere generates temperatures tip to 1,600°F. Beyond the atmosphere, the outside temperature drops to -454°F. -close to absolute zero -and gone is the atmospheric pressure that keeps man's organs from exploding like a blood bomb...
...rocket, he coasts for several seconds at high but steady speed; when the second stage blasts off, he can take it, and his body is also ready for the acceleration of the final blast. On reentry, the g forces loosed by deceleration are likely to be far more perilous. Impact of hitting even the thinnest outer layer of the atmosphere head-on at 18,000 m.p.h. is like driving a car through a blast furnace against a cliff at 60 m.p.h. To slow down, the pilot may have to glide in at an angle of no more than...
