The Flight Team has been carefully monitoring Attitude Control subsystem performance since return to ANS on Monday evening. It is generally felt that this type of event would have been sufficient to cause the spacecraft to lose inertial reference prior to the star processing software fix made Monday evening. Telemetry indicates that they are performing well. Recreation of the problem in a test environment allows teams the opportunity to confirm that the star processing software fix uplinked earlier this week resolves the problems which had been causing recurring fault protection activation. The spacecraft is stable in Array Normal Spin.
Indications are that all spacecraft subsystems are performing well.
The Flight Team is uploading Flight Software Build 8.0 today and tomorrow. Selected flight software modules are being updated to improve Attitude Control subsystem performance. Related activities are scheduled to be completed by tomorrow afternoon. Gamma Ray Spectrometer Random Access Memory load activity begins late in the afternoon on Saturday, May 29. The Mars Observer Camera Mars Imaging Final Design Review was the subject of Mission Manager's Operations Planning Meeting this morning.
