Research In Microgravity On Earth

Report surveys ground-based facilities for research in microgravity. Facilities fall into three categories: Those providing true microgravity environment for short time, such as rockets, airplanes, drop towers, and drop tubes; those emulating one or more aspects of microgravity environment, such as electromagnetic or acoustic levitators; and those aiding in understanding behavior of systems in microgravity, such as model furnaces and computational facilities. Concentrates on material-processing facilities of NASA at Lewis Research Center, Marshall Space Flight Center, and Jet Propulsion Laboratory. Describes facilities briefly, provides names, and telephone numbers for further information and arranges for qualified researchers to use facilities.
