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 strip-down inspections will be described and the lessons learned stated.
