...leveled Hiroshima. If it hit in the ocean, he predicted, it would cause a tsunami (commonly called a tidal wave) hundreds of feet high, flooding the coastlines of surrounding continents. "Where cities stood," he said, "there would be only mudflats." A land hit, he calculated, would blast out a crater at least 30 miles across and throw up a blanket of dust and vapor that would blot out the sun "for weeks, if not months...
...washboard topography made up of a series of parallel cliffs, each the size of Mount Rushmore. Elsewhere the spacecraft spotted bright crustal fractures crisscrossing older, darker ones, suggesting that the ice is being cracked and recracked by similar subsurface sloshing. Still elsewhere the ship photographed a crater whose floor seems to have swelled up from beneath--its central peak pushed above its rim--probably the result of slushy seas deforming the crater after it was created. "We'd never seen the surface at this resolution," says James Head, a Galileo scientist. "It's a little bit like putting it under...
...Shoemaker will finally get his dearest wish. When NASA's Lunar Prospector blasted off toward the moon last week, it carried a small capsule containing an ounce of Gene Shoemaker's ashes. On brass foil surrounding the capsule was an image of Arizona's Meteor Crater, where Shoemaker trained NASA's astronauts. After reaching the moon this week, the spacecraft will ease into a 63-mile-high orbit, peer down and begin a search for minerals, gases and any evidence of water. Then, some 18 months from now, Prospector will crash onto the lunar surface, carrying Gene Shoemaker's ashes...
...will be a dramatic turnaround in the Japanese trade position, the export sector will grow, and investors will see the budget deficit getting much bigger." But Courtis warned the plan could backfire: "The Japan problem isn't over. If they raise taxes too much, the economy is going to crater...
Hurtling in from space some 16 million years ago, a giant asteroid slammed into the dusty surface of Mars and exploded with more power than a million hydrogen bombs, gouging a deep crater in the planet's crust and lofting huge quantities of rock and soil into the thin Martian atmosphere. While most of the debris fell back to the surface, some of the rocks, fired upward by the blast at high velocities, escaped the weak tug of Martian gravity and entered into orbits of their own around...
