Scientific paper

In parallel to in-flight operation as primary Electric Propulsion Subsystem (EPS) onboard the ESA SMART-1 spacecraft the PPS -1350-G qualification life test is on-going. On May 2004, 4200h firing and 3160 cycles have been achieved. Cold cycles tests have also been performed. This paper shows the evolution of the main performances along the life. This contribution also presents the results of characterisation tests in an extended voltage/flow domain (in the 250-1000V, 2-7.5 mg/s range), performed in the frame of the French research group on Plasma Propulsion involving CNRS, CNES, and Snecma Moteurs.
