...them is out of the question. (A single pint of water weighs about a pound, and every pound you fly to the moon costs about $50,000.) The LRO, however, will not be traveling alone. Launched on the same booster will be another entire spacecraft known as the Lunar Crater Observation and Sensing Satellite (LCROSS...
...site of the explosion is marked by a 15-foot crater. The devastation wrought all around resembles the aftermath of a wartime aerial assault. Investigators are picking through the rubble that lies all around for clues. Rescuers in the building have been conducting a search of their own, hoping to lift survivors to safety. After hours of rummaging, they locate the body of Kamal Ahmed, the hotel's much-liked general manager. But he is no longer alive, to the despair of his family...
...hanging from tree branches as a warning against banned pop music. They've since devised more lethal uses for the recording medium. After a recent roadside bombing of an American convoy in Ghazni province that killed three Afghan police officers, streams of tape were found ahead of the blast crater. The reflective quality of the tape, soldiers said, had allowed militant spotters to be forewarned of the arrival of enemy forces and to time the explosion from afar. Once the detonation cord was traced back to a village compound, the bombers were long gone...
...controversial paper was written by geoscientists Gerta Keller of Princeton University and Thierry Addate of the University of Lausanne, in Switzerland. Both researchers knew that challenging the impact doctrine would not be easy. The asteroid charged with killing the dinosaurs, after all, left more than the Chicxulub crater as its calling card. At the same 65-million-year depth, the geologic record reveals that a thin layer of iridium was deposited pretty much everywhere in the world. Iridium is an element that's rare on Earth but common in asteroids, and a fine global dusting of the stuff is precisely...
...Keller and Addate worried that we were misreading both the geologic and fossil records. They conducted surveys at numerous sites in Mexico, including a spot called El Peñón, near the impact crater. They were especially interested in a 30-ft. layer of sediment just above the iridium layer. That sediment, they calculate, was laid down at a rate of about 0.8 in. to 1.2 in. per thousand years, meaning that all 30 feet took 300,000 years to settle into place...
