Microgravity, which is the 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 provides researchers with a near weightless or microgravity environment for a duration of 5.18 seconds.

The facility is currently used by NASA funded researchers from around the world to study the effects of microgravity on physical phenomena such as combustion and fluid physics, to develop and demonstrate new technology for future space missions, and to develop and test experiment hardware designed for flight aboard the International Space Station or future spacecraft. It was originally designed and built during the space race era of the 1960s to support research and development of space flight components and fluid systems, in a weightless or microgravity environment. The Zero-G facility has been operational since 1966. The Zero-G facility is one of two drop towers located at the NASA site in Brook Park, Ohio. The Zero Gravity Research Facility is NASA’s premier facility for ground based microgravity research, and the largest facility of its kind in the world.
