Where are the Zero Gravity Research Facility and the NASA Glenn Research Center located at?
Zero Gravity Research Facility The Zero Gravity Research Facility at the NASA Glenn Research Center in Cleveland, Ohio is a unique facility designed to perform tests in a reduced gravity environment. It has successfully supported research for the United States manned spacecraft programs and numerous unmanned projects. The facility uses vertical drop tests in a vacuum chamber to investigate the behavior of components, systems, liquids, gases, and combustion in such circumstances.
Gravity Discovery Centre The Gravity Discovery Centre and GDC-Observatory Gingin is a "hands-on" science education centre, situated on the site of the Australian International Gravitational Observatory, near Gingin, north of Perth, Western Australia.
