We describe the principles of electrostatic flight in tenuous plasma around solar system bodies. The lack of an atmosphere, low gravity levels, and unknown surface soil properties pose a very difficult challenge for all forms of known locomotion at airless bodies. The environment near the surface of asteroids, comets, and the Moon is electrically charged due to the Sun’s photoelectric bombardment and lofting dust, which follows the Sun’s illumination as the body spins. If a body with high surface resistivity is exposed to solar wind and solar radiation, Sun-exposed areas and shadowed areas become differentially charged. Our work in this field is motivated by the E-Glider, i.e., the Electrostatic Glider, which provides an enabling capability for practical electrostatic flight at airless bodies, a solution applicable to many types of in situ missions, which leverages the natural environment. The E-Glider is a small spacecraft that uses, instead of avoids, the charged environment in the solar system for near fuel-less circumnavigation, allows in situ characterization of the plasmasphere of planetary bodies, and reduces the risk of landing on hazardous surfaces.
