Institute of Space and Astronautical Science (ISAS), Japan Aerospace Exploration Agency (JAXA)), Sagamihara, Kanagawa Japan, There has been evidence of dust levitation in space, first on the Moon. At asteroid Eros, dust craters, or ponds, have been observed by the Near Earth Asteroid Rendezvous mission (NEAR) in 2001, suggesting the presence of electrostatic forces able to alter the regolith distribution. Since then, work has been done to simulate and partially reproduce the phenomena observed. More recently, observations from the Hayabusa spacecraft validate predictions on particle sizes due to solar interaction. In future missions to these bodies, we hope for additional close approaches, touchdowns and mobile landers. Thus local gravity and dust properties become a greater concern for the success of the mission. As an asteroid rotates, it induces charging cycles from photoemission of electrons and collection of solar wind electrons and ions. Hence, the local surface of the small body goes from positive to strongly negative potential. However, to date, there is still little known about the coupling between electrostatic force and the low gravitational attraction on small bodies. In this paper, we revisit the modeling and theory of dust levitation for Near Earth Asteroids, and we give a measure of relative importance of the electrostatic and the gravitational fields., 資料番号: AA0064734054},
