...here, in the early 1980s, that Klimley first saw an attack by a great white, on a 400-lb. elephant seal. The shark rose almost entirely out of the water, with the massive seal in its jaws. "It was stunning," he recalls. "The shark ambushed the seal, then came back several times to take three or four bites out of it. I had never seen anything like it." Since then Klimley has analyzed more than 130 videotaped white-shark attacks. All seem to follow a pattern. The powerful first bite usually takes place underwater, and the first sign...
...house without my chaps, my six-gun and my ten-gallon hat. Or rather, my two-gallon hat. I was six years old. I thought I was Marshal Dillon. Nowadays a successful yuppie won't leave the house without his four-wheel-drive sport-utility vehicle boasting 225 lb.-ft. of torque. He's 40 years old, and he thinks he's Mark Trail...
...undisputed star of the week, however, surpassing even the rocks, was the 25-lb. Sojourner, which Rob Manning, Pathfinder's flight-systems chief engineer, dubbed "The Little Rover That Could." Having inched its way down the steeply inclined lander ramp, the six-wheeled Sojourner crept gingerly onto the Martian surface early last week and, in its first official scientific experiment, shoved the nose of its X-ray spectrometer into the dust at the foot of the lander...
Nonetheless, when Pathfinder actually reached the upper limits of Mars' wispy atmosphere, it would still have been possible for NASA to put the ship into the rough. The 1,256-lb. polyhedron-shaped pod was screaming toward the planet at 16,600 m.p.h., a speed that caused it to experience deceleration forces nearly 20 times as great as than Earth's gravity. In order to survive, the spaceship had to approach the planet at an angle of about 14.2[degrees]. "Go in too steep and you could crash and burn," says Pathfinder project scientist Matthew Golombek. "Go in too shallow...
Still another spacecraft might be launched to fly by Europa and drop a 20-lb. sphere onto its surface. Striking the frozen crust with the force of a suitcase full of TNT, the cosmic cannonball would release a mushroom cloud of ice particles into space; the mother ship would then fly through the crystalline mist, collect a bit of it and carry it back to Earth for analysis...
