The attitude and station keeping maneuver #68 were delayed one day due
to DSN DSS-54 antenna being unavailable.

The next attitude maneuver is scheduled for Tuesday 01/21/2014.

The Near Earth Network continues to performed range tests in order to
analyze the range bias with the Flight Dynamics Facility.

DSN is having problems with several antennas.  DSS-54 is down an
additional day per week (during daylight hours) for continued corrective
maintenance in relation to the azimuth drive noise that had the antenna
red from 12/20/2013 to 12/27/2013.  The DSS-45 transmitter is red from
1/13/2014 to 1/20/2014.  The DSS-34 transmitter has issues, but is
working with a reduced uplink power.  There are also problems with a
couple of the 70m DSN antennas, but ACE does not use those.

ACE had passes with WS1 on 1/8/2014, 1/9/2014 and 1/14/2014 to free up
time on DSN this past week.
