...command from its computer, Mariner 6's electronic gear poured out an endless stream of data from the red planet-information about the density and composition of its atmosphere and its varying surface temperatures. On board the ungainly, 850-lb. ship, whose four solar panels gave it the look of a stubby windmill, tiny transmitters also sent back to earth, some 60 million miles away, the best close-up portrait man has ever had of Mars. At week's end, an identical twin named Mariner 7 moved into position for similar electronic observations. Mariner 6 aimed its close...
...long after Eagle's successful touchdown, the Soviet space vehicle Luna 15 met with a less fortunate fate. The unmanned ship dropped from her lunar orbit and headed for the moon's surface. Telemetered data picked up by Western observatories indicated that Luna had hit too hard to survive. To most space experts, the failure was one more proof that the Russians are months if not years behind the U.S. in space technology...
...small, 3-ft.-sq. box directly behind them in the lunar module. Despite its deceptively simple appearance, the 100-lb. package was the heart of the LM's communications system. Known as a signal processor, it accepted the astronauts' voices as well as 900 other signals-telemetric data on heartbeats, for example, pressure readings in the cabin, data from the computers-and imposed them on a single "carrier" frequency of 2,282.5 megahertz. An amplifier increased the signal's power from half a watt to 20 watts, the strength of a small ham-radio transmitter...
...communications web stretches around the earth-and above it. Key parts of the network are the huge radiotelescope dishes at Goldstone, Calif., Madrid, Spain, and Canberra, Australia, 17 ground stations, four U.S. Navy ships scattered over the seas and eight communications planes-all receiving and transmitting vital bits of data throughout the mission. No one is more aware than the astronauts themselves of how impossible a flight would be without such support...
Drug users insist that marijuana, amphetamines, LSD and other psychedelic agents give them pleasure, a euphoric "high" and a marvelous expansion of consciousness. A growing body of medical data suggests that they are kidding themselves on all these counts. Psychiatrists and psychologists are coming to the conclusion that potheads and acidheads do not turn on simply for pleasure and thrills, but in a futile attempt to escape profound depression; that if they get high, it is only in an ecstatic defense; and that they do not wind up with an expanded consciousness but with a decidedly contracted...
