ACE Weekly 10/07/2009 - 10/13/2009

All ACE spacecraft subsystems are performing nominally.

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

No maneuvers have been completed this week.  The next attitude maneuver
is scheduled for Friday 10/16/2009.

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

None

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

Data Capture:  100%  DOY 277-284 2009

DOY 279 10/06/2009 - Multi-Mission Operations Center (MMOC) Test
There were no problems receiving telemetry or sending commands with
DSS-34.  The spacecraft was commanded to high-rate and SSR data from the
previous pass was redumped.  ACE reformatted data was forwarded for NOAA
space weather for the entire pass.  ACE Science Center (ASC) continues
to block ACE real-time data from the MMOC.

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

DOY 283  10/10/2009  S-ACE-0466  S09-0008  Increase in SBE_CT_B
SSR B Single Bit Error Count (SBE_CT_B) increased from 5646 to 6089
since last checked on DOY 272 (09/29/2009).  SBE_CT is tracked as a
measure of SSR health.
IMPACT:  Minimal.  Single Bit Errors are automatically corrected by the
SSR.  No non-correctable errors (Hard Single Bit Errors & Double Bit
Errors) have occurred throughout the mission.
