...long-range benefits of this effort are not yet clear. With client regimes in power in Angola and Mozambique, the Russians have buckled a kind of Red belt of influence across the middle of the continent. Now if they can hold on to Somalia and bring Ethiopia into their orbit, they will have hooked a suspender onto the belt. Meanwhile the other gallus is shaping up along the Atlantic coast of Africa, involving Zaire, the Congo, Benin and Guinea-Bissau...
...satellite Lageos, conceived and designed by scientists in the Center's division of geoastronomy, may provide a measure of continental drift. The satellite, now in orbit, is two feet in diameter, and is covered with 426 small mirrors. Scientists at two different ground stations direct lasers at the satellite. By precisely measuring the round-trip time of each beam, they hope to determine the distance between the stations to an accuracy of two centimeters--the distance many think Europe and North America drift apart each year. The researchers' accuracy is at about ten centimeters now. But most of the research...
...face the sun, and painted a heat-absorbing black on the other side. The total weight of the sail and the instrument-packed ship mounted in a hole at its center will be only 5,000 kilograms (11,000 lbs.)-a payload that could easily be launched into earth orbit by a rocket...
Once the package has been hauled by the shuttle into near-earth orbit, a small rocket will push it to escape velocity. At about 100,000 kilometers (60,000 miles) above the earth, the framework will be assembled and the sail deployed automatically...
...year-old farmhouse in West Berlin. He calls it "a forced learning process in the simultaneous skills of driver, messenger, clerk, telex operator and office manager." Aikman went to Berlin after four years in Hong Kong. Both cities, he notes, "are outposts of Western enterprise and freedom within the orbit of Communist states...
