...high-tech kind. Photographed from 440 miles out in space, they are views of the earth by the U.S.'s newest and most versatile earth-observing satellite, a multieyed robot called Landsat 4. Launched last July, it has been faithfully circling the globe, swinging from pole to pole and back again once every 98.9 minutes, taking electronic shots of every spot on the planet, except a small region around the poles. These images are a source of information about crops and forests, oceans, mineral resources and the atmosphere...
...Pole Vaulter Billy Olson passes 19ft. and keeps looking...
Billy Olson used to dream of flying, not over crossbars, over rooftops. "I imagined myself jumping off fences and just flying," he says, "running down the street, flapping my arms and . . . taking off." For those who have never traveled by catapult, this is the sensation of pole vaulting...
...when everyone, including Warmerdam, thought it was impossible. "It was like the sound barrier," he says. Before anyone else made 15 ft., eleven years later, Warmerdam had done it 43 times. He held the world record 15 years. "Of course I go back to when the pole was a pretty stable instrument," he explains. Warmerdam's first bolt of bamboo carried him over high hedges and cringing livestock all across his father's spinach farm in California's San Joaquin Valley. His records were built of bamboo; steel and aluminum poles came along...
...bright planet like Jupiter would ruin the observations. For protection, IRAS has a highly polished gold-plated sun shield. But its main insurance is its precise course. Circling the earth once every 103 minutes at an altitude of 560 miles in an orbit that carries it from pole to pole, IRAS roughly follows the line on the earth's surface where day meets night. Along this pathway, the telescope can always face 90° away from the sun, yet catch rays of sunlight on its solar panels to make electricity to power itself...
