The Zero Gravity Research Facility was built in 1966 as part of NASA's Centaur upper-stage rocket development program. In order to ensure proper firing and functioning of upper-stage rockets, NASA needed to understand the behavior of fluids (importantly, the liquid gases fueling the rockets), in the reduced gravity where they would fire.
The Zero Gravity Research Facility is a vertical vacuum chamber used for dropping experiment payloads for testing in microgravity. It enables the investigation of the behavior of components, systems, liquids, gases, and combustion when dropped in vacuum.
NASA's Zero Gravity Research Facility, located at the Glenn Research Center in Cleveland, Ohio, is a 145 m vertical shaft, largely below the ground, with an integral vacuum drop chamber, in which an experiment vehicle can have a free fall for a duration of 5.18 seconds, falling a distance of 132 m.
The NASA Glenn Research Center has a 5 second drop tower (The Zero Gravity Facility) and a 2.2 second drop tower (The 2.2 Second Drop Tower). Much of the operating cost of a drop tower is due to the need for evacuation of the drop tube, to eliminate the effect of aerodynamic drag. Alternatively the experiment is placed inside an outer box (the ...
In the late 1980s NASA began to consider replacing its previous neutral-buoyancy training facility, the Weightless Environment Training Facility (WETF). The WETF, located at Johnson Space Center, had been successfully used to train astronauts for numerous missions, but its pool was too small to hold useful mock-ups of space station components of the sorts intended for the mooted Space Station ...
NASA considered the flight EVA to be a total success, and Aldrin again returned to McDonogh to perform a post-mission evaluation of the EVA. The post-mission evaluation verified the value of using neutral buoyancy simulation training before attempting all of the EVA tasks while wearing a pressure suit and working in the hostile environment of ...
NASA Johnson Space Center has facilities such as the Space Vehicle Mockup Facility (SVMF), Virtual Reality Laboratory (VRL), and Neutral Buoyancy Laboratory (NBL). The SVMF uses the Partial Gravity Simulator (PGS) and air bearing floor (PABF) to simulate the zero-gravity and the effects of Newton's laws of motion. [41]
NASA's Plum Brook Station is located off Taylor Road, between Bloomingville and Bogart, south of Sandusky, Ohio. This remote site was established by NASA to facilitate large-scale testing of dangerous equipment. The In-Space Propulsion Facility, designed to perform full-scale test-firing of large rockets, is one of several facilities at the ...
