ACE Weekly 10/19/2010 - 10/25/2010

All ACE spacecraft subsystems are performing nominally.

========================================================================
Orbit/Attitude:

No maneuver was completed this week.  The next attitude maneuver is
scheduled for Thursday 10/28/2010.

=======================================================================
OCRs:

None

========================================================================
Activities:

Data Capture:  100%  DOY 290-297 2010

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 294  10/21/2010 S-ACE-0551  G10-0067  ANSR notifications not received
ANSR notifications were not received by FOT throughout the support.  
On-Call Engineer went to MOC and confirmed pass activities were 
executing nominally.  MMOC System Administrators (SAs) notified.  
Analysis showed while ANSR was contacting the mail server, an error 
was preventing ANSR notifications from being sent.  In addition, SAs 
discovered a file permission issue had caused ANSR's logging mechanism
to crash, thus preventing further analysis of the ANSR error.  File 
permissions were modified and ANSR recycled.  FOT began receiving
notifications.
IMPACT:  FOT monitored support activities real-time.

DOY 295  10/22/2010  S-ACE-0549  G10-0065  DSS-27 Power Outage
D27 experience a power outage 90 minutes into ACE's support.  Telemetry 
offline for remainder of support.  (DR#N106665)
IMPACT:  No data or commands for 120 minutes.  No data to NOAA Space
Weather Prediction Center (SWPC) for 120 minutes.  Manual intervention 
required to complete pass activities.  All data recovered during SSR 
playbacks on subsequent supports.

DOY 297  10/24/2010 S-ACE-0550  G10-0066  IONet Mail Server Down
MMOC team stopped receiving notifications following DOY 296 support.
On-call Engineer came in on DOY 297 to assess status of the pass once 
nominal BOT notifications were not received.  Once pass activities 
confirmed nominal, ACE Engineer notified MMOC team that notifications 
were not being issued.   
IMPACT:  Unable to monitor Pass activities.  Delayed FOT 
response if an anomaly had occurred during DOY 297 support.
IONet Mail Server back up prior to start of DOY 298 ACE support.
