MICROGRAVITY IS A state of almost total weightlessness experienced onboard a spacecraft outside of the Earth's atmosphere once the spacecraft's rocket motors are turned off. The crew and equipment onboard a spacecraft are not completely weightless because factors such as uneven distribution of mass in the spacecraft produce a very small gravitational field.
