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

GRD-166 - 09/01/06 - OpenSSL and new Perl libraries were installed on the
ACEDDS for the upcoming DSN SPS Transition.

============================================================================
Ongoing Activities:

Attitude Training - The OE's will begin training the remainder of the FOT on
attitude determination, maneuver planning, and maneuver execution beginning
September 11.

RIONET - The transition to the RIONET on String 3 will tentatively occur
around mid-September.  

Space Link Extension (SLE) - ACE SLE version 2.1 was delivered to the
Library on April 28, 2006.  The delivery to the ACE MOC will not occur until
after the MOC is converted to the RIONET.

Multi-Mission MOC - The FOT has begun supporting the effort to determine the
feasibility of transferring to a multi-mission MOC.

Automation - Development for the next ROBOTT automation release in ongoing
on String 3 and the ACEDDS.  A ROBOTT SPS release is expected no later than
September 18.

============================================================================
Extra Activities:

The FOT transitioned to the online Goddard SOARS database for anomaly
reporting on September 1, 2006.

The kickoff Configuration Control Board (CCB) Meeting was held September 6. 

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

DOY 250 (09/07/06)  S-ACE-0001(G06-0081) Thruster Setup Procedure Ver. 2
The thruster setup procedure was exported a second time while waiting for
the MOPSS box to turn yellow.  This changed the version from a2006250_01cmds
to a2006250_02cmds.  
IMPACT:  None.  The procedure was valid and the FOT used it.

DOY 250 (09/07/06)  S-ACE-0002(G06-0082) Incorrect Maneuver Summary Report
The maneuver summary for DOY 250 2006 did not include the spacecraft weight
(field was blank).  Investigation found that the maneuver summary report for
DOY 242 2006 did not have the correct spacecraft weight (incorrect:
1395.266lbs, correct: 1395.615lbs).
IMPACT:  The corrected information was sent to FD.
