5. Possible Applications:
"Interest in asteroids goes well beyond the purely scientific, and includes investigation of ways in which asteroids could be deflected from a collision course with Earth, or mined for their unique and abundant resources.
All in all, asteroids could be the perfect low-gravity laboratory for advancing the physics of granular media. Such media- agricultural grains, pharmaceutical powders, ores and chemicals- are the basis for hundred-billion-dollar industries, but their behavior continues to baffle physicists and engineers".
