Activities:

Data Capture:  98.56%  DOY 339-346 2010
There were minor gaps during redumps on DOY 346 resulting in 87 minutes
of data loss.

All ACE passes starting on Friday 12/10/2010 (DOY 344) are using DSN's
new DCD (Data Capture and Delivery) system.

There is a higher than normal risk of data loss from October 2010
through February 2011.  If there are problems with the passes, it may
not be possible to acquire additional DSN time.

========================================================================
Anomalies:

DOY 343  12/09/2010  S-ACE-0564  G10-0079  MUS CMD process terminated
The MMOC SLE (MUS) cmd process (ace-d27-cmd) terminated unexpectedly 2
minutes after beginning of track.  The MUS CMD process was restarted
within 6 minutes.  This last occurred on 10/08/2010 (AR#G10-0057)
IMPACT:  Manual intervention required.  Activities delayed 6 minutes.

DOY 345  12/11/2010  S-ACE-0565  G10-0080  SLE TLM disconnect
Although MUS reported active binds, telemetry was not reaching the MOC.
The FOT manually disconnected and re-established an active realtime
telemetry bind.  MMOC began receiving telemetry.  This last occurred on
11/05/2010 (G10-0070).
IMPACT:  Manual intervention required.  Activities delayed 95 minutes.

DOY 347  12/13/2010  S-ACE-0566  G10-0081  MUS CMD process terminated
The MMOC SLE (MUS) cmd process (ace-d27-cmd) terminated unexpectedly 2
minutes after beginning of track.  The MUS CMD process was restarted
within 6 minutes.  This last occurred on 12/09/2010 (AR#G10-0079)
IMPACT:  Manual intervention required.  Activities delayed 15 minutes.
