...Wood, a young physicist from California's Lawrence Livermore Laboratory, delighted his colleagues (although he did not exactly convince them) with a plan to give the earth a virtually limitless energy supply. He suggested tapping the energy of a mini-black hole in orbit around the planet. From a spacecraft orbiting at a safe distance, pellets would be fired at the hole. This would create so much heat that the energy could be converted into microwaves and beamed down to earth. Even Wheeler, who is now at the University of Texas, and his former student, Kip Thorne, once proposed construction...
...hole's "event horizon." Anything crossing this border would be stretched spaghetti-thin, pulverized by gravitational tidal forces, and sucked into the singularity. To an observer outside?say an astronaut watching his abandoned craft plunge into the black hole?the result would be different. Because of relativistic effects, the spacecraft would appear to move ever more slowly, and closer and closer to the event horizon, without ever reaching...
DIED. Mstislav Keldysh, 67, prominent Russian mathematician who helped shape his country's space program; in Moscow. His own research centered on rocketry and spacecraft, but as chief of the Soviet Academy of Sciences from 1961-75, Keldysh oversaw a national network of scientific projects and organizations. His working knowledge of English helped him maintain contacts with many Western scientists, and he professed a desire for Soviet-American cooperation in space research...
Last week Aho's group went ahead on its own and dedicated a 14-acre clearing near Washington's Mount Rainier as a Spacecraft Protective Landing Area for the Advancement of Science and Humanities (SPLAASH). The saucer enthusiasts plan to ask the Pentagon not to attack aliens who try to land there. How will they recognize their earthly crash pad? Through mental telepathy, says Aho. "If we send out the right kind of thoughts, we will communicate." Just in case the vibes are bad, the landing site is also clearly marked by ropes and a sign reading NEUTRAL...
...been slated to make a space walk; Romanenko was to remain behind at Salyut's open hatch. Both were wearing a new type of space suit equipped with a radio and an hour's supply of oxygen. Thus when cosmonauts are working outside an orbiting spacecraft, they require no umbilical link to the mother ship other than a simple tether to keep them from drifting off. Everything was going smoothly during Grechko's extraterrestrial stroll until Salyut passed over the western Pacific Ocean-out of range of Soviet ground stations. Suddenly, Romanenko, who was not tethered, jumped...
