Mars' low atmospheric pressure and arid, windy climate provide an environment that supports the triboelectric charging of dust. A laboratory experiment has been performed to demonstrate that the vertical motion of dust is sufficient for this charging mechanism to produce strong electric fields capable of creating electrical discharges in a low-pressure CO2 atmosphere. Discharges have been visually and electronically detected, and the discharge frequencies and intensities have been measured. The range of pressures required to efficiently produce these discharges has also been examined, demonstrating that electrical discharges can occur under conditions expected on the Martian surface. Additionally, a simple theoretical model has been created to constrain the parameters involved in the dust charging experiment. This model supports the ideas developed in the experimental phase of the project.
