The Zero-G is NASA's premier facility for conducting ground-based microgravity research. The facility is used by investigators from around the world to study the effects of microgravity on physical phenomena such as combustion, fluid physics, biotechnology, and materials science.
Microgravity, a condition of relative near weightlessness, can only be achieved on Earth by putting an object in a state of free fall. The Zero-G facility allows experiment hardware to free fall a distance of 432 feet (132 m) and provides researchers with a near weightless or microgravity environment for a duration of 5.18 seconds.
