...data sent back to earth by two Mariner spacecraft more than 60 million miles away seemed to offer as little hope as the lunar rocks that life would be found elsewhere in the solar system. Flying past the planet Mars, the small, instrument-packed spacecraft detected no evidence of nitrogen, an indispensable ingredient of life on earth. Probing the upper reaches of the Martian atmosphere, they failed to find anything like the ozone shield that protects the earth's surface from the sun's deadly rain of ultraviolet radiation. Even their stunning close-up photographs from only...
...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...
...beef sandwich aboard the Gemini 3 flight in 1965 and littered the spacecraft interior with crumbs, the astronauts were allowed a supply of bread. To withstand the pure-oxygen atmosphere, which quickly dries bread and makes it crumbly, the slices of white and rye bread had been flushed with nitrogen, a process that keeps them fresh for two weeks...
...procedure. If the astronauts and the Apollo craft are indeed harboring alien organisms, the bugs could escape into the air when the hatch is opened, or be washed into the ocean while the astronauts are donning their biological suits. If the organisms are fond of oxygen or nitrogen-or thrive in salt water -they could begin to spread and multiply. Most scientists agree that the chances of life on the moon are remote, and some believe that any moon organisms would have reached the earth long ago on particles ejected from the moon during meteor impacts. If they are wrong...
...Auto-Ceptor crash-restraint system is especially useful for drivers of minicars. In case of collision, big nitrogen-inflated nylon balloons pop out of the steering column and dashboard, pinning motorists to their seats and keeping them from flying through the windshield. They deflate immediately after a crash, leaving motorists free to get out. Developed by Eaton, Yale & Towne Inc., the balloons would replace shoulder straps, which few motorists use any way (seat belts would still be needed for protection in rolling accidents). The Auto-Ceptor system works automatically: balloons inflate in one twenty-fifth of a second when...
