Santiago 9-meter antenna (used by NASA's Near Earth Network) is getting
closer to having a range test with ACE.  Santiago will track ACE
(downlink only) within the next 2 weeks and the range test will be
scheduled for April.  The FOT will monitor the spacecraft via the WS1
ground station.  The test will be used in planning for the DSCOVR
mission.
