What the scientists were unable to detect conclusively was any sign of life. One chemist placed samples of lunar dust and rock chips under a 300,000-power microscope and found no evidence of lunar organisms, either living or fossilized. Another chemist did detect a trace of carbon, an element essential to life. But it was mainly volatile hydrocarbons that are familiar ingredients of lubricating oil; they might well have come from tools, or from the cabinets in which the samples had been placed...
...warned that even at the spacecraft's relatively close distances, vegetation would be all but unobservable. The two Mariners, moreover, were designed only to determine whether Mars could support life. At week's end, investigators were already mulling over two important observations. Mariner 6 had failed to detect any nitrogen -an ingredient of all earthly life -but it found signs of water in the form of ice in the Martian atmosphere or on the surface...
...phase of earthly life has profited more than medicine. By adapting the compact electronic equipment designed to monitor the life functions of space travelers, doctors are now able to watch a wardful of seriously ill patients from afar. By modifying a meteoroid sensor, they can detect minute body tremors caused by such neurological disorders as Parkinson's disease. Another adaptation involves the so-called "sign switch": intended to be actuated by the mere movement of an astronaut's eyes so that his hands will be free, it has already been installed in a motorized wheelchair for paraplegics...
...entire spectrum of these frequencies. Furthermore, by building radio telescopes on the back side of the moon, astronomers will be able to escape completely from the radio interference caused by earth's increasingly electronic civilization. Without the background "noise" to contend with, radio astronomers will be able to detect much fainter radiation from space, perhaps even the weak signals of a distant civilization...
...civilian, he is paid more than any other astronaut ($30,054 a year, v. Aldrin's $22,650 as an Air Force colonel and Collins' $20,400 as an Air Force lieutenant colonel), a fact that has stirred resentment. There are men in the space program, in fact, who detect behind Armstrong's supercool all-American image a rigid character who has more faith in the perfectibility of machines than of people. "He's all scrubbed up on the outside," says a NASA official, "but inside he has nothing but contempt for the rest of mankind that isn't willing...
