NASA announced that researchers had recorded unexpected, huge flashes of light in the upper atmosphere that might affect atmospheric ozone and present potential problems for high-altitude research planes. The flashes occurred above a severe thunderstorm in the Midwest in the summer and were recorded aboard NASA's DC-8 Airborne Laboratory, based at Ames Research Center, Moffett Field, California. (NASA Release 93-167; W Post, Sep 24/93; AP, Sep 23/93)
NASA announced that results from a Spacelab crystal growth experiment flown aboard the Space Shuttle last summer had brought researchers closer to understanding the molecular structure of proteins; such understanding would aid scientists in developing more effective disease-fighting, anti-parasitic drugs. (NASA Release 93-166)
NASA announced that flight tests with a NASA research aircraft last week had demonstrated the first precision automatic approaches and landings using Differential Global Positioning System (DGPS) navigation satellite signals. The procedures were carried out without using complex processing techniques. (NASA Release 93-165)
