...with neat precision. Early Bird, first satellite to be sent aloft by Comsat (Communications Satellite Corp.), climbed as high as 22,300 miles above the earth, then curved down as low as 776 miles. When this original orbit had been analyzed and Early Bird was at an apogee, a signal from the earth fired a small rocket motor to give just enough extra speed to put the satellite into a circular orbit that matched the earth's 24-hour period of rotation. In effect, the intricate electronic package put together by Hughes Aircraft picked a spot high above...
When the rocket cleared the atmosphere, the windscreen was jettisoned; the reactor and its conical support section went into orbit 800 miles above the earth. As soon as SNAP's scientists were convinced that the proper orbit had been attained, they sent a signal that told the reflector mechanism to reduce neutron leakage. Slowly the nuclear reaction started; heat built up in the core, and a magnetic pump circulated the metallic coolant at 1020°F. through tubes in the skin of the support structure. The inner ends of 2880 pellets of a germanium-silicon material were heated while...
...began during the 16-week New York newspaper strike of 1963 when Gallery Owner Robert Graham was at a loss for a way to advertise. To signal shows, he hit on having each artist design his own flag. His idea was so successful that other galleries followed suit, and Graham, along with Barbara Kulicke, wife of a New York painter and framemaker, founded the Betsy Ross Flag & Banner Co. Before long, 35 artists had made nylon flags to fly outdoors and felt banners to hang indoors like tapestries. So far, shows of their work have traveled to 30 U.S. museums...
...program-a character not unlike Wernher von Braun -and is all set for a preposterous last-reel countdown. He shoots it out with the Gestapo, slaughters scores of guards, finally pulls the switch that opens the doors that let out the light that serves as a signal to Allied planes. The bombardiers drop in their eggs just in time to abort an intercontinental missile called "the New York rocket," lifting off for parts unknown. In fact, Germany's underground rocket factory was never bombed. Operation Crossbow probably won't be so lucky...
...five months to the day since Khrushchev's lieutenants had deposed him, and this glimpse of him quite naturally raised a lot of questions. How was he faring? Where was he going? What had he been doing lately? Did his reappearance in public signal a possible return to some kind of office? Nikita himself would not or-more likely-could not answer. To requests for an interview, he snapped: "Not now, some time." Still, most of the answers were plain...
