Microgravity is a unique environment where the effects of gravity are reduced or removed. This environment is created in freefall. In space, freefall is achieved by “falling around” the Earth in the International Space Station; on the Earth, freefall is achieved in special research aircraft that fly in parabola-like maneuvers. Microgravity is very important in the study of Space Science because the processes and phenomena normally hidden by dominant gravitational effects become more easily observable.
