What NASA did not reckon with was the unexpected intensity of solar disturbances accompanying the current sunspot cycle. More sunspots have appeared than were anticipated, great magnetic storms and solar flares are raging on the sun, and more charged atomic particles-which make up the solar wind-are being hurled into space. The stronger solar wind heats the thin gases in the outer fringe of the earth's atmosphere, which causes them to expand outward into the orbit of Skylab. That increases the drag on the craft...
...teachers started from scratch and wrote a textbook with the help of the Colorado office of energy conservation. The course involves 390 students in six Jefferson County schools. Points are made mostly through class activities. A sample: "Catch the Sun," a lab experiment that measures the heating power of solar energy on a thermometer. A key exercise calls for students to record their household energy use?kilowatt-hours of electricity, cubic feet of natural gas?on special grid sheets. In this way they can compare their energy use with the much smaller world average. Most students take to heart what...
...High School has created a course in energy careers. Students pursue individual projects, such as assessing the effectiveness of the city's fuel use, and are aided by Shaeffer & Roland, an environmental management firm. Says Teacher Frances Vandervoort, grandly: "By 1980 there a will be 300,000 jobs in solar energy alone, and we are helping prepare our students for these opportunities." At suburban Evanston Township High School, an architectural drawing program includes the study of solar heating, wind generators and maximum use of insulation. At a recent science fair at Brooklyn's Roy Mann Intermediate School, there...
...smaller rocket motor enabled scientists to cram a dozen instruments into Pioneer's drum-shaped "bus," 2.5 meters (8.2 ft.) in diameter. In addition to carrying devices that will map the Venusian atmosphere and cloud formations, analyze the composition of the clouds and measure the interaction between the "solar wind" and the atmosphere, Pioneer 1 will use radar to penetrate the clouds and produce a rough topographic map of much of the Venusian surface. Previous radar scans, made by the giant radio telescope in Arecibo, P.R., have already detected some craters, a large chasm, possible volcanoes, mountainous areas...
...editorial entitled "Sun Day Sermon" (Crimson, May 1), Dr. David Jhirad, Acting Director of the Union of Concerned Scientists (UCS), was misquoted as having said that solar energy could provide for the entire energy needs of the United States before the end of the century. The error was mine. In fact, on the basis of a comprehensive two-year study performed by Dr. Jhirad and his colleagues, Dr. Jhirad concludes that aggressive implementation of the solar option (encouraged by federal purchasing programs and tax incentives), combined with efficient fossil-fuel use, could result in solar energy providing one-quarter...
