Because of the force of gravity, some experiments are difficult or impossible to perform. Therefore, some researchers design experiments for microgravity conditions. Scientists research biotechnology, combustion science, fluid physics, fundamental physics and materials science in microgravity. This primer defines each research area and illustrates the benefits of microgravity research. A brief discussion of the microgravity environment of orbiting spacecraft is included.
