Electrical activity on the surfaces of Mars and the moon originates from vastly diverse sources, posing a barrier to human and robotic planetary exploration missions. Global dust storms have re-distributed a cover of dust throughout Mars. Because of the many grain collisions in the dust-laden atmosphere, dust levitated by these storms and regular dust devils is predicted to be electrostatically charged. On the other hand, dust on the moon's surface is projected to be electrostatically charged as a result of the solar wind, cosmic rays, and the photoelectric effect of solar radiation. Dust that is electrostatically charged has a strong ability to stick to surfaces. Atmospheric dust falling on solar panels on NASA's Mars exploration rovers has proven that it may reduce their performance to the point where the rover becomes useless. As the Apollo missions to the moon shown, lunar dust adhesion may obstruct both manned and robotic lunar exploration efforts.
