The observation was received and displayed. No anomalies were noted. The Spacecraft on-board computer detected a difference between the expected and actual values for the solar array wings during a scheduled wing maneuver of 30 degrees. The present limit for difference is 8.0 degrees and the safemode was activated when this limit was exceeded by the -V2 wing. A previous solar array slew of 30 degrees approximately 24 hours earlier had executed normally.
Initial analysis indicates a nominal safemode entry with all subsystems in a safe state.
Representatives from ESA are at GSFC and are supporting the investigation. Steps are under way to get the spacecraft operational on a Health and Safety Load to provide more positive and efficient ground operations control, and to facilitate the return to science operations when the problem is better understood and resolved. Plans for returning to science operations, currently on hold, will be developed after the problem is better understood.
