...their endless search for water, oil and minerals beneath the surface of the earth, prospectors and scientists have used everything from divining rods to sophisticated seismic devices. But more often than not, they have had to fall back on costly and time-consuming drilling to probe the earth's secrets. Now, New Mexico's Sandia Corp. has developed new tools for preliminary subsurface exploration that may do in minutes or hours what now takes days and even months to accomplish. The new devices: high-speed, instrumented projectiles dropped from aircraft or propelled by rockets...
Sandia's earth-probe projectiles have been proposed to investigate the suitability of remote sites along Colombia's Atrato River for the location of dams. Eventually, in addition to a role in mineral exploration, the projectiles may be used to find water, to place deep-sea anchors, and to bury radioactive fuels re-entering the atmosphere after the flights of nuclear rockets. Shot from unmanned spacecraft orbiting distant planets, one Sandia scientist proposes, the projectile probes could even help determine if there are water tables beneath the surface of Mars and Venus...
...gravity by removing them from the centrifuge, the animals gained approximately 10% in body mass. Conversely, weanling rats raised under normal gravity lost about 10% of their mass-much of it in body fat-within 24 hours after being placed in the higher artificial gravity of a centrifuge. To probe the fat-depletion phenomenon further, Oyama plans to induce arteriosclerosis in rabbits by feeding them high-cholesterol diets and then putting them in a centrifuge to determine if the disease is lessened under conditions of higher gravity...
...carnage, followed in turn by further hints of negotiations. The most recent talk about talks became intense in late December and early January, when the North Vietnamese said officially that they would agree to discussions if the U.S. stopped bombing North Viet Nam. Washington followed up with a deep probe of Hanoi's intentions. The chief question throughout was whether Hanoi would give assurances that it would not militarily exploit a bombing cessation. This demand was part of the "San Antonio formula" laid down by Lyndon Johnson in September and later denned as meaning that Hanoi should not increase...
Carrier v. Bomber. Because the Russians consider the U.S.'s seaborne air-power to be a major threat in case of all-out war, one of their favorite tricks is to harass and probe U.S. carriers. Soviet destroyers and trawlers try to break a carrier's screen of protective smaller ships in order to force the flattop to change course while launching or landing aircraft and thus maybe dump a few planes into the sea. In the air, bombers of the Soviet navy^s 750-plane, land-based air force continually test to see how close they can approach...
