Abstract: In this paper propulsion systems for space station control is discussed.It is concluded that propellant consumption will be a major cost factor. Electric propulsion system offers specific impulse at least an order of magnitude higher than those of chemical thrusters, so propellant masses can be reduced by the same factor. Electic propujsion systems will be used for high impulse tasks such as drag compensation and orbit transfer.

Key words: Propulsion system, Space Station
