...climb into a pressure suit and go outside to reel the limb in. If that fails, the arm will have to be jettisoned in space. For unless the shuttle's big, heat-shielded cargo doors are shut tight, Columbia will not survive the scorching descent through the atmo sphere back to earth...
Racing toward Saturn at 54,000 m.p.h.-20 times as fast as a speeding bullet-the 1,800-lb. spacecraft came within a cosmic hair of the planet's stormy cloud tops, clearing them by 63,000 miles. Then it plunged downward behind the huge gaseous sphere and passed through a large gap near the edge of the thin disc of icy debris that forms Saturn's multi-hued rings. Finally, like a pebble in a great celestial slingshot, it was sent hurtling off toward Uranus on a new course created by the powerful pull of Saturn...
...creation, an ordinary planet, even the second largest in the sun's family, hardly seems likely to awe or surprise. Yet, remarkably, Saturn still has that power, as the Voyager 1 spacecraft so dramatically showed last November. Swooping within 78,000 miles of the luminous ringed sphere, the little robot sent back a collection of full-color images as dazzling as any ever received from deep space...
After only a year or so of operation, enough plutonium (about 35 Ibs.) could be generated in a small reactor to build two or three bombs of the type dropped on Nagasaki. The plutonium would be formed into a hollow sphere containing a small neutron source that might be made of radium and beryllium. The plutonium itself would be wrapped in a beryllium or uranium reflector, which helps contain neutrons and prolong the chain reaction. This shield would in turn be covered by a layer of TNT charges, the most critical aspect of the design. The charges would have...
McIntosh insists that many women will not be satisfied with the lives they have led until they see the difference between true feminists, "who can define success in terms of a family," and women's libbers, who retain a traditional bias against the private sphere "and view success in the way men always have...
