S.6 Spacecraft Propulsion - 13- Spacecraft Propulsion is characterized in general by its complete integration within the spacecraft (e.g. satellites). Its function is to provide forces and torques in (empty) space to: - transfer the spacecraft: used for interplanetary travel - position the spacecraft: used for orbit control - orient the spacecraft: used for attitude control SMART-1 Spacecraft Mission to Moon to demonstrate innovative and key technologies for scientific deep-space missions. Nov. 2003 – Sept. 2006 While jet propulsion systems for launching rockets are also called primary propulsion systems, spacecraft, e.g. satellites, are operated by secondary propulsion systems.
