| Outline of Final Research Achievements |
Satellite charging is usually avoided for discharging phenomenon. However, this research investigated the postive use of satellite charging by ion/electron emitting for possible propulsive force on the satellite dynamics. A charged satellite on an Earth orbit is propelled by Lorentz force as a charged partcile moves in a geomagnetic field. The Lorentz force itself is quite small, while it can be used for maintaining a formation flight. A charged spacecraft in a heliocentric orbit with a charged tiny asteroid in its proximity produces Coulomb force, This Coulomb force with a combination of gravity force is shown to change the asteroid orbit quite moderately.
