...comets form, molecule by molecule, out of frozen gases beyond the outermost planets. They pick up bits of dust and start drifting ever so slowly toward the distant sun. When they gather speed as they approach the sun, their surface gets hotter, turning some of the frozen gas to vapor and freeing some of the dust to form the comets' glowing heads and tails. When an old comet disintegrates, it leaves bits of fluff to wander in space...
Next morning Cooper was back in his Faith 7 capsule. As he lay on his back, the ten-story-high launch assembly swayed gently. The thin skin of the Atlas popped and clinked with expansion and contraction. Vapor whistled with pitch-pipe tones through the liquid oxygen release valve. Gyros purred-and, to the astonishment of control-center monitors, Cooper's respiration rate dropped to twelve per minute. Astronaut Cooper apparently was taking a catnap...
...real estate. An 18-hole standard course takes 125-175 acres, but 18-hole par-three takes only 40 because of its smaller tees and greens and shortened fairways. This also enables compact courses to be built much closer to cities; some 200 of them are equipped with mercury-vapor lamps and are thronged far into the night...
...response to tiny fluctuations in temperature. Special filters allow only a very narrow band of the infrared, between eight and 14 microns, to fall on the thermistor. The filter rejects the shorter infrared waves omitted by the sun and reflected by the moon. The earth's atmosphere, where water vapor, ozone and carbon dioxide absorb other portions of the infrared, also acts as a sort of filter. However, one can easily derive the temperature of the moon from the intensity of infrared radiation in the band transmitted between eight and 14 microns...
First quick studies of Stratoscope's data showed that water vapor and CO2 are indeed present, but scarce. Now the data have gone to the University of California for closer analysis, as scientists continue their search for any evidence of the possibility of Martian life...
