...density of CO2 increases, the gas acts somewhat like a one-way mirror. Rays of life-giving sunlight can pierce it, heating the surface of the earth. But when this heat is radiated back by the ground in the form of longer infra-red waves, it is screened by the CO2, which absorbs it, thereby raising its own temperature and that of the ground. This so-called greenhouse effect is dependent on the concentration of atmospheric CO2: the greater the amount, the warmer the earth may become...
...blue cloud of exhaust fumes, 46 of the diesel-powered 40-ton machines roared through Red Square. One Western government observer's assessment: "A very businesslike-looking weapon." Already in service in East Germany and the Soviet Union, the T-72 has a 115-mm. gun with an infra-red and laser range-finding system for accurate fire through fog or at night. Because the gun is loaded automatically, the tank requires a crew of only three; crews of four are required by its predecessor, the 37½-ton T-62, as well as by the tanks of NATO...
...trouble comes in the form of a beetle-shaped Soviet satellite about 10 ft. long and 3 ft. wide, equipped with very-high-frequency radio antennas and small, square infra-red scanners that work in tandem with radar to direct the killer toward its orbiting prey. The anti-satellite interceptor (ASAT) has a parabolic "dish" antenna that homes in on the target satellite and gets the ASAT - actu ally a space bomb - close to the target, where it detonates. The ASAT goes off like a super hand grenade, spraying the victim satellite with metal-piercing fragments. ASAT's main...
Presuming Voyager 2 overcomes its troubles, the twin flight is a unique project. The Voyagers go elaborately equipped for sightseeing. They carry wide-and narrow-angle television cameras, cosmic ray detectors, magnetometers, infra-red spectrometers and radiometers, as well as instruments for detecting and recording ultraviolet radiation and radio emissions from the planets. They will, it is hoped, give man his closest look yet at Jupiter, a planet that contains more matter than all the other planets in the solar system put together. The pair will also devote a good deal of attention to four of Jupiter...
Fading Light. Astronomers have known of the existence of the star -dubbed MWC 349-since the 1930s. But it was not until this past year that researchers studying the star through the 2.3-meter (90 in.) infra-red telescope at Arizona's Steward Observatory and the 91-cm. (36 in.) infra-red scope in Ames' Kuiper Airborne Observatory, realized how unusual it was. In simultaneous observations, the scientists discovered that the star, already ten times the size and 30 times the mass of the sun, was surrounded by a great glowing disc some 224 million km. (approximately...
