...must then travel to Earth across the vast ocean of the cosmos. The dispatch may move at the speed of light, but the journey can still take hours, years, epochs--turning current events into history long before we ever learn of them. Signals from the Cassini spacecraft, currently studying Saturn's moons, take 84 min. to reach us; the supernova whose cataclysmic birth astronomers observed earlier this year was already fading millions of years...
...Pentagon geeks that searches obsessively for the next big thing in the technology of warfare, is 50 years old. To celebrate, DARPA invited Vice President Dick Cheney, a former Defense Secretary well aware of the Agency's capabilities, to help blow out the candles. "This agency brought forth the Saturn 5 rocket, surveillance satellites, the Internet, stealth technology, guided munitions, unmanned aerial vehicles, night vision and the body armor that's in use today," Cheney told 1,700 DARPA workers and friends who gathered at a Washington hotel to mark the occasion. "Thank heaven for DARPA...
...exploration have always been the unmanned ships--and right now they're enjoying something of a golden age. The U.S. currently has no fewer than 11 interplanetary probes scattered about the solar system; five are orbiting, roving or approaching Mars alone, and the others are targeting Mercury, the sun, Saturn and numerous comets or asteroids. One probe is heading for a never before rendezvous with Pluto, a destination it won't reach until...
This spring three of the rugged ships stand out from the rest. Near Saturn, the Cassini orbiter, launched by the Jet Propulsion Laboratory, just executed a dramatic dive through an icy geyser that reaches 950 miles (1,530 km) into space from the Saturnian moon Enceladus, and there are plans to follow that up with even higher-risk maneuvers. In May NASA's Phoenix Lander will set down in Mars' arctic region in search of water ice. And later this month NASA and the European Space Agency will retire their Ulysses solar surveyor after a 17-year mission that...
Before the orbiter attempts that maneuver, it will execute two flybys of the moon Titan, whose opaque orange atmosphere has been increasingly pierced by the spacecraft's radar. And this summer Cassini will make an unusually high orbit above Saturn's massive B ring, promising unique images of the ring, spread like an immense halo around the planet. The ship will also have the rare opportunity to observe the sun cross the plane of the ring from south to north, literally shedding light on the B ring's complex particle structure. "We want to know what a particle would look...
