Thruster Hot-fire Ground Verification Tests have been performed in an attempt to understand the thruster anomalies that were experienced on the FLTSATCOM Flight 2 spacecraft (IRON 6392). While the test objectives of determining the effect of gas bubble ingestion, cold starts with isolation valves closed, effect of seat leakage on first pulses, and susceptibility to 'choking' were accomplished, the exact cause for the anomaly was not established. No deleterious effects from cold starts with isolation valves closed were observed. (Author)
