The Lorentz force acts on electrostatically charged objects moving in the Earth's magnetic field. This implies charged space debris orbit can be controlled and debris may be removed by controlling its charge amount. In this paper, we propose various charge control sequences for debris removal and investigate their performance via numerical simulations. The proposed sequences focus on monotonically decreasing semi-major axis, increasing the eccentricity, and decreasing perigee distance. Finally, we optimized the charge control sequence by a combination of these sequences.
