...first big glitch occurred on July 12, when a computer detected contamination in Challenger's hydrogen fuel and aborted the launch 3 sec. before takeoff. The 112-ton spacecraft blasted off 17 days later, but 5 min. 15 sec. into the flight, a monitoring device reported that one of the three main engines seemed to be heating up to a dangerous 1,950 °F. That sensor alerted the onboard computer, and for the first time in the 24-year history of the U.S. manned space, an engine was shut down in flight. But as the craft hobbled bravely heavenward...
Fortunately, there proved to be no need for more sweeping measures. The operation, which took 2 hr. 53 min., went smoothly. A team of six doctors headed by Navy Captain Dale Oller, chief of general surgery at Bethesda, snipped out a 2-ft.-long portion of Reagan's colon, the section containing the 2-in.-long polyp, and sewed the intestine back together. "Our patient, our President is doing very, very, very well," Oller announced about an hour after the surgery was completed. "The operation went absolutely perfectly." There were no signs of the complications that sometimes develop during...
...High Noon ? Did you miss the bus to work because you caught Stagecoach at 3 a.m.? Well, suffer from horse-opera hangover no more! Now there's Silverado, the Cuisinart western! Silverado dices, splices, chops, co-opts, hones and clones every oater archetype in just 2 hr. 13 min.; that's less than 1% of the time it would take you to sit through the collected works of John Wayne! And if you act now, we'll throw in nine, yes, nine of the cinema's rising stars--Kevinklinescottglennrosannaarquettejohncleesekevincostnerbriandennehydannygloverjeffgoldblumandlindahunt--almost none of whom look at home on the range! That...
...biggest ovations last week were reserved for a more subtle use of computer-graphics technology: a touching, 5-min. animation titled Tony de Peltrie. Created by a design team from the University of Montreal, it depicts a once famous musician who sits at a grand piano in the middle of a hardwood floor, tickling the keys and tapping his white leather shoes to the beat of his memories. In striking contrast to the awkward, robot-like characters in earlier computer films, De Peltrie looks and acts human; his fingers and facial expressions are soft, lifelike and wonderfully appealing. In creating...
Last week's SIGGRAPH attendees got a taste of that insight during a 3-min. film sequence, produced at Lawrence Livermore Labs, that showed in a few seconds what biology teachers have labored for years to make clear: the precise mechanism by which molecules of DNA fold upon themselves to form thick strands of chromosomes. "It's something you could never do with a camera," says Livermore's Nelson Max. The audience at SIGGRAPH greeted his technological tour de force with enthusiastic applause...
