Presentation Abstract

Dust storms on Mars can last for months at a time and can reach peak speeds of 30 m/s. However, considering Mars's incredibly thin atmosphere, these storms should be significantly slower, if at all. We hypothesize that the triboelectric effect, friction-based electrification, in conjunction with the large levels of radiation, due to Mars thin atmosphere and lack of a magnetic field, may generate lift force upon Martian dust to produce such large storms. The triboelectric effect has been shown to cause sparks when shaking dust in a low-pressured environment, and radiation has shown its potential to cause lift; an example, a gold leaf lifting once exposed to x-rays. The aim of this research is to thoroughly investigate this phenomenon and examine the possible connection of both radiation and triboelectric effects may have on Martian dust storms.
