Description
Dust is a major concern for NASA Lunar and Martian missions due to its abrasive nature tendency to cover equipment. However, little is known how dust behaves in low gravity environments. This paper studies the methodology and validation of a novel apparatus that will simulate low gravity using upward coulomb forces. A parametric study found that the optimized charging parameters to create a charged particle stream, using corona discharge, was a wire-plate spacing of 25 mm at 8 kV and 30 mm at 9 kV. Future work will expand the platform to simulate low gravity in turbulent conditions.
