There was only one scheduled Deep Space Network (DSN) pass in the
past week, and all spacecraft subsystems performing normally.
Approximately five hours prior to the scheduled start of the DSN pass,
a PACI (Payload Attitude Control Interface) reset occurred. The last
time a PACI reset occurred was on July 30 and the spacecraft entered
Safe Mode as a result. A Flight Software (FSW) patch was developed and
installed in late August. This patch successfully re-enabled the PACI
and prevented the spacecraft from entering Safe Mode as expected.
Although the root cause of the resets has not been found data is still
being collected to help determine the cause.

The second part of flight sequence 12 was successfully retransmitted to the
spacecraft and is now active waiting for its start time on December

Sequence SC011 is the active sequence. Sequence SC012 is on-board and
part one is waiting to start its execution on December 6.
