I know of the work of Atchison & Peck (2010), Lammarzahl and Dittus (2008) and Lammarzahl et al. (2008) that rules out the possibility of electrostatic cause of FAs as a result of the Lorentz Force. What I want to know is: Is an electrostatic charge of about 10000 C realistic to consider for the spacecrafts? I mean a smeared out electrostatic charge on the surface of the spacecrafts? I am about to complete a paper on the topic and want to know if I am working on a realistic path.
