Station-keeping maneuver #74 is scheduled for Friday 3/13/2015.  The
next attitude maneuver is scheduled for Tuesday 3/17/2015.  The reason
for the maneuvers on different days is due to very short passes with
insufficient time for 2 maneuvers.

A review for closing the B latch valves is scheduled for Monday
3/16/2015 with a expected execution on Tuesday 3/17/2015.

Data Capture:  100%  DOY 060-067 2015

MMS is scheduled to launch 3/13/2015 ~0300z (DOY 072).  MMS passes are
not usually during the ACE viewperiod, but DSN antenna time is limited
due to several missions.  No data loss is expected in March, but the
risk of data loss is higher than usual.
