Antarctica is not the only spot where ozone levels are low, says Donald Heath, a NASA scientist. Tests over Arosa, Switzerland, since the 1920s have shown an average ozone loss of 3%, mostly in the past ten years. And Heath believes he has found another hole. Centered over Spitsbergen, Norway, 700 miles from the North Pole, it is one-third the size of the Antarctic hole. Heath claims the region's ozone loss has been 1.5% a year for the past six years and says this location fits models of CFC-caused loss...
...Antarctic team's assertions are bold, since the tests are not completed. But even if the ozone change is not induced by man, says NASA Research Scientist Richard Stolarski, "it would do us well to understand, because we're going to have to react whether it's natural or man-made. We need to know if these changes are greater than in the past or if we are just paying more attention to them now. And we should know that as soon as possible...
...space shuttle Challenger, Ride seemed to find the prospect of another shuttle assignment a bit too scary. A member of the commission that investigated the disaster, Ride declared in March that the shuttle was unsafe and that she would not board it again. Currently riding a desk at NASA, she said last week that she was ready for lifting off again. Why the change of heart? NASA has done a "real good job" redesigning and testing the rocket boosters that helped cause the accident, explained Ride. All the astronauts are now eager, she adds...
...last week: satellite launching. Martin Marietta, which manufactures Titan-class rockets for the Air Force, signed an agreement with Federal Express to send aloft its ExpressStar communications satellite in 1989. President Reagan had opened the way for the new industry last month, when he an- nounced that NASA will drastically reduce the number of commercial cargoes carried aboard the space shuttle...
...only be held in contempt. How can the Reagan Administration ask the average wage earner to go on paying and paying for Social Security benefits that he may never see, for an astronomical defense budget, for aid to the contras and for yet another NASA shuttle? It is incredible that any tax reform would delete child-care credits, double-earner exemptions and IRA write-offs. What is miraculous is that after using half of my take-home pay for child care, my husband and I have enough to make payments on our home...
