Activities:

DOY 205 07/23/2008 - The Multi-Mission Ops Center (MMOC) successfully tested
sending ACE NO_OP commands to DSN's Test Facility (DTF-21).  There was no
impact to ACE's operations pass with DSS-66.

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

DOY 207  07/25/2008  S-ACE-0341  G08-0078  DSS-66 Telemetry Loss
DSS-66 experienced 1% data loss throughout the pass.  All data was recovered
through redumps.  The redumps took 80 minutes to complete.  Note that the
initial data dump was 150 minutes.  Additional time was available on the
following day with DSS-27.
IMPACT:  All data was captured through redumps.  On a per frame basis, the
initial data loss was only 1%.  However, in terms of complete major frames
(128 second cycle), the initial data loss corresponds to 20% (5 hours).
