These charts represent data recorded during our Trajectory Correction Maneuver (TCM) thruster firings yesterday. Thruster firings were planned to done in groupings – or “segments” – of 63 firings per segment. The first chart is annotated to show the three firing attempts. The first segment was full duration but only partially successful. The second and third attempts failed. Possible causes (under investigation) include valve malfunction and fuel supply issues.
