...planet Mars follows such an eccentric orbit around the sun that it is accessible to probing spacecraft from earth only one month out of every 25-a period referred to by scientists as "the window." All through November the window was open, but the first U.S. attempt to peek inside failed when the Mariner C spacecraft, unable to jettison its 300-lb. fiber-glass protective shield, could not attain the necessary speed...
...Kennedy a three-stage, 100-ft. Atlas-Agena rocket blasted downrange over the South Atlantic missile track in a perfect launch. Five minutes later, the protective shield, a redesigned shroud of magnesium thorium, was jettisoned right on schedule. Thirty-seven minutes after that, from a 115-mile-high parking orbit over the Indian Ocean, the rocket engine reignited, kicking the 575-lb. Mariner D payload toward Mars at the required speed-25,600 m.p.h. At week's end all was going well with Mariner D and its 138,-000 individual parts. But the spacecraft still has quite...
...years, the loudest noises in the aerospace business have been the rumble of liquid-fueled boosters blasting spacecraft into orbit, the sharper roar of solid-fuel military missiles climbing into their long trajectories, and the continuing, wordy battles between the promoters of each type. Now, back of the racket, can be heard the insistent voice of still another competitor in the rocketry race-the hybrid that manufactures its power by combining liquid oxidant with solid fuel. Detractors may scoff that the hybrid combines all the dangers and difficulties of both solids and liquids. Its champions are confident that...
Marxism." By any name, it is spreading through the Soviet orbit and causing considerable ferment. Czech economists have openly attacked the Marxist economic system, and Czech President Antonin Novotny recently stressed the necessity of "material incentives" for the workers. Even more important for its potential effect on the Communist world, the new way of thinking has given encouragement to the long-suffering consumers of the Soviet bloc, who have begun to sound off loudly about the inefficiencies of a system that provides them with so few comforts...
Even the luckiest people need a star to sigh by-or so it seemed when Astronaut Scott Carpenter, 39, went backstage to visit Broadway's Fanny Girl Barbra Streisand, 22. "I'm really honored," bubbled Barbra, clearly launched into orbit. "I'm always interested in scientific and medical things. Whenever I go to the dentist, I can spend three, three-and-a-half hours there talking about nerve endings and things like that. But about those things up there-I don't know what a star's made of. Do you?" "Good looks-talent...
