Description
The Zero Gravity Research Facility provides a near weightless or microgravity environment for a duration of 5.18 seconds. This is accomplished by allowing the experiment vehicle to free fall, in a vacuum, a distance of 432 ft. (132 m). The facility can provide a microgravity test environment for a fraction of the cost conducting an experiment in space and provides the best gravity levels of any of NASA’s ground based low gravity facilties.
