We investigate the interaction of dust with space plasmas and spacecraft with a special focus on the typical values of equilibrium charge and the typical time scales required to reach them. It is well known that objects in space become charged through the combination of a number of different processes: the photoelectric effect, the collection of free electrons and ions from the plasma, and by secondary electron emission due to the impact of highly energetic particles. In the equilibrium state, currents between the plasma and the charged object are balanced. However, perturbations on the orbit of the charged body and perturbations of the distribution of plasma particles may lead to time dependent deviations in charge. In this study, we are i...
