We have studied the interaction of five different insulator materials that have been rubbed over martian soil simulant using the Mars Environmental Compatibility Assessment (MECA) electrometer, which is an instrument intended to be part of a future Mars lander mission. The electrometer was designed primarily to study (1) the electrostatic interaction between the martian soil and the insulator materials, which are attached to the electrometer. The MECA/Electrometer is also capable of measuring (2) the presence of charged particles in the martian atmosphere, (3) the local electric field strength, and (4) the local temperature. We will present results that indicate that a martian soil simulant can triboelectrically charge up an insulator surface. Data taken at 6 mbar and at room temperature will be presented. We will also discuss methods of neutralizing these insulator surfaces, and will present data for some of these methods. This research was supported in part by a NASA/ASEE Summer Faculty Fellowship, and the Florida Space Grant Consortium.
