ACE Weekly 08/17/2007 - 08/24/2007

All ACE spacecraft subsystems are performing nominally.  ACE was launched 10
years ago on 08/25/1997.

============================================================================

No maneuvers were performed this week.  The next attitude maneuver is
scheduled for Friday, 08/24/2007.

OCRs:

DOY 233 (08/21/2007)  GND-185  ACE SLE v2.1 Software Install
ACE SLE v2.1 user software provides the ability to send CLTUs built by TPOCC
to DSN's F-CLTU Service Provider.  This software is installed on 2 Red Hat
Linux workstations (ac1sle1 & ac2sle2).  ACE SLE v2.1 was delivered on April
28, 2006, but its use was delayed by the transition to the Restricted IONet.
Telemetry will continue to be sent from DSN in the original SFDU format and
will not be sent via SLE.

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

Space Link Extension (SLE) - Configuration and testing continues.  After
much effort, the ACE MOC was able connect to the DSN Test Facility (DTF-21)
and send NO_OP commands on Wednesday 08/22/2007 and Thursday 08/23/2007.
Configuration and testing will continue.

Planning continues for integrating ACE operations into a multi-mission ops
center (MMOC).  The current TPOCC mission software will be replaced by ITOS
and the ROBOTT automation software will be replaced by GMSEC tools (CAT,
GREAT, ANSR, etc).  The ADS attitude software will be replaced by
MSASS/MTASS.  The timeline for when this will occur has not yet been
determined.

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

DOY 229  08/17/2007  S-ACE-0219  G07-0073  AC3PR3 Printer Not Printing
The String 3 printer continues to have problems printing.  Unknown if this
is a hardware, software, configuration or network problem.
IMPACT:  Time and effort troubleshooting
