A solid fuel pulsed plasma thruster (PPT) has been designed, built and flight qualified for the LES-8/9 program (due to be launched in March 1975). The satellite attitude control system will contain six PPTs for orbit acquisition, east-west stationkeeping, three-axis attitude control and station changes. Each thruster has fuel for 2650 lb-s total impulse and at 25 w generates 69 micropounds thrust at 1100 s specific impulse. A prototype thruster has passed flight qualification shock and vibration tests and operational lifetime. (Modified author abstract)
