Understanding how small particles flow in the Martian environment is crucial for the success of the science payload on the 2009 Mars Science Laboratory rover. Triboelectric charges (charges associated with moving particles) result in an increase in particles charges causing them to stick to each other and components of the sample handling system. On Earth, these charges can be minimal due to the amount of water in the atmosphere. These conditions may be worse on Mars where there is virtually no moisture to dissipates electrical charging. We have designed an electrostatics experiment to characterize the amount of electrical charge that might be added on the particles of rocks from drilling and moving them through the sample handling system. Testing was conducted in a simulated Mars environment. Results have provided some groundwork-data regarding the electrical charging nature of processed rocks and minerals as they interact with the construction materials of the MSL sample handling system.
