A fully automated landing of a transport aircraft was made using only engine thrust for control. Landing was a McDonnell Douglas MD-11 using a Propulsion Controlled Aircraft (PCA) system at NASA's Dryden Flight Research Center. PCA is expected to become an important back-up system in the event of a loss of an aircraft's hydraulic flight control system. (NASA Release 95-149; Fla Today, Sep 24/95; Av Wk, Sep 4/95)
Scientists at NASA's Marshall Space Flight Center have determined a three-dimensional atomic structure of an important enzyme from one of four species of parasites that cause schistosomiasis. Using highly specialized X-ray equipment and protein crystallization techniques developed for space-based microgravity research, they were able to perform an important step leading to the use of drugs and vaccines. Schistosomiasis affects 200 to 300 million people and is second only to malaria in cause of death worldwide. (NASA Release 95-211; Htsvl Tms, Dec 3/95)
