...other, quite legal, ways in which we are steadily bringing about the end of the world. Just for an example, there's the Greenhouse Effect gone wild. Our heavy industry, oil heat, and combustion in general are putting too much CO2 into our air. CO2 in our atmosphere absorbs ultraviolet radiation from the sun (reflected off the earth) as heat. This is called the Greenhouse Effect. It was important in the evolution of the earth into a life-supporting planet. The world is getting hotter and hotter. When it gets hot enough, the polar ice caps will start to melt...
...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 2,200 miles above the red planet seemed to indicate that Mars is a cold, cratered globe, altogether inhospitable to life as man knows...
...organisms that found shelter in a relatively hospitable ( -94°F.) region near the edge of Mars' southern polar cap, where Mariner 7 concentrated its cameras and instruments. There, he said, they might have drawn water from the polar ice and protection from the sun's ultraviolet radiation under a cloud of carbon-dioxide particles...
...ship, lost no weight at all. Locked away with 16 other men-including two doctors and a NASA public relations man-the astronauts spent their free hours playing pingpong, watching color TV and reading the accounts of their voyage (which are sent through an air lock and sterilized by ultraviolet light). After their leisurely evening meals (sample menu: T-bone steak, a bottle of 1964 Chateau Lafite Bordeaux), the astronauts usually chatted with their families through the glass partition...
Seeking to answer that age-old puzzle, scientists from Caltech's Jet Propulsion Laboratory at Pasadena crammed Mariners 6 and 7 with vastly improved electronic gear, ranging from tape recorders to miniature computers to extraordinarily sensitive infra-red and ultraviolet measuring equipment. The total cost of the Mariners and their launch vehicles: $148 million...
