The increased lifetime demanded of state-of-the-art telecommunications satellites has necessitated the tribological redesign of an electric thruster pointing mechanism which is currently used in-orbit on the scientific ESA telecom satellite ARTEMIS. The change from dry to liquid lubrication will be described and results of in-vacuo tests under oscillatory motion will be presented. The tests were performed both at Austrian Aerospace (Austria) and at ESTL (UK). Results of stripdown inspections will be described and the lessons learned stated.
