Also on the Columbia were two devices designed to map various geological resources. An imaging radar, a 30-foot long rectangular antenna, bounced sonar waves off terrain and oceans to produce images of the reflecting surfaces. And a multispectral radiometer scanned selected areas at ten infrared wavelengths...
Scientists hope to use the data from both the imaging radar and the radiometer, combined with pictures from Landsat satellites, to identify the most useful infrared band for surveying specific minerals...
...antiaircraft missiles from the Soviets. Altogether, the week's news reinforced an impression that the Administration is improvising day to day in Middle East diplomacy rather than following a careful strategy. Said one American lobbyist for Israel, alluding to U.S. efforts to build a radar-eluding airplane: "Reagan's Middle East policy is like the Stealth-you can't see it or hear it, but it sure bombs...
Much of their information comes from an unmanned Pioneer spacecraft. Since it began orbiting Venus three years ago, it has studied the planet's weather by photographing changing cloud patterns and lifted its veil with a radar beacon, mapping 93% of Venus' shrouded surface. Though the planet has continent-size land masses topped by a mountain a mile higher than Everest, it does not seem to be rent by the earth's major mountain builder: continental drift. Rather, the key tectonic process appears to be volcanism, accompanied by lightning, flows of lava and an otherworldly version...
...Whenever a different driver enters the automobile, he inserts a plastic card in the dashboard that adjusts the seats, air conditioning and mirror to his specific desires. Shock absorbers automatically regulate the car's suspension to accommodate the number of passengers. Once the car is under way, a radar-activated cruise-control senses vehicles ahead and applies the brakes when necessary. In addition, an ultrasonic system warns the driver of any obstructions up to ten feet behind the vehicle. If it starts to rain, electronic windshield wipers adjust their speed to the amount of precipitation...
