The authors have investigated the dynamics of small dust grains ejected from the Martian satellites, considering both the solar radiation perturbation and electromagnetic forces since the grains move in a magnetized plasma. Lorentz forces can dramatically change the nature of the trajectories, resulting in, for example, prolonged lifetimes for submicron-sized grains moving through their idealized model. Though temporal changes of the solar wind were ignored and the authors only followed grains for 20 days or less, the authors suggest that a permanent, non-uniform and time-dependent dust halo of grains predominantly around 0.1 {mu}m may exist about Mars.
