...been ladled too many over-sanguine assurances in the past, only to be confronted later with the familiar due bills of heavier manpower commitments, steeper costs and higher casualties. Nonetheless, one of the most exhaustive inquiries into the status of the conflict yet compiled offers considerable evidence that the weight of U.S. power, 21 years after the big build-up began, is beginning to make itself felt. Within the next 18 months or so, White House officials maintain, the increasing impact of that strength may bring the enemy to the point where he could simply be unable to continue fighting...
Then they put it to the crucial test of action. First they fired Surveyor's vernier engines for 33 seconds to consume more fuel and reduce the craft's landing weight. New instructions were radioed to Surveyor's memory bank and programmed into ground-based computers. As a result, the craft's main retrorocket began firing at a height of 26 miles above the lunar surface, instead of the originally planned 52 miles. It shut off at an altitude of only 4,400 ft., instead of 40,000 ft., after braking Surveyor...
...Biosatellite was stabilized in orbit to provide less than 1/100,000th of the earth's gravity for its tiny occupants. It also was equipped with a strontium 85 source that irradiated some of the organisms with gamma rays to determine whether the effects of radiation were different under weight less conditions...
Generally, the M-16 rates high praise from the men in Viet Nam, who find its light weight (7.6 Ibs.) and rapid rate of fire ideal for jungle warfare. With proper maintenance, which will always be necessary to prevent jamming, the fighting men in Viet Nam should also find it a lethally reliable friend in need...
Working with bits of bone, fossilized impressions in stone and educated intuition, scientists have cleverly deduced the appearance, weight, speed and even habits of animals that have long been extinct. Now, University of Arizona Paleontologist-Biochemist Tong-yun Ho has gained an unexpected new insight into the metabolism of many of these extinct animals. He has learned to take their temperature...
