Data Capture:  100%  DOY 032-039 2015

Santiago (Near Earth Network) continues their ranging tests while ACE is
in the low downlink rate.  The data will be used in preparing for the
DSCOVR mission.  No tests have been scheduled for the upcoming week.

The DSCOVR launch has slipped several times.  Because pass activities
are initiated via ground command, ACE is very flexible in inserting
passes when previously occupied antenna time becomes available.

2/5/2015 DOY 036 - NASA/NISN has 2 SCDs (Small Conversion Device) at
VAFB for routing data from AFSCN.  These SCDs also route ACE data from
AFSCN to NOAA SWPC via the GSFC MMOC when the usual SWPC antennas are
not available.  The second SCD has been transitioned to be solely for
DSCOVR data.
