ACE Weekly 12/04/2013 - 12/10/2013 All ACE spacecraft subsystems are performing as expected. ======================================================================== Orbit/Attitude: Type Attitude Date 12/10/2013 DOY 344 2013 Thrusters 2R 4R+ 4R- Duration 7:00 min Start 16:14:16z Stop 16:21:16z HGAStart -8.97 deg HGAStop +9.01 deg SunStart 14.17 deg SunStop 17.98 deg SpinStart 4.9750 rpm SpinStop 4.9765 rpm Nutation 0.08 deg Firing 35 pulses FuelUsed 0.1150 lbm FuelRemain 110.0476 lbm FinalSCMass 1344.308 lbm The next attitude maneuver is scheduled for Tuesday 12/17/2013. ======================================================================== OCRs: None ======================================================================== Activities: Data Capture: 100% DOY 337-342 2013 A second DSS-15 demo had been scheduled for Wednesday 12/4/2013 (DOY 338) to acquire extra antenna time. DSN cancelled the demo due to servo maintenance. Fortunately, LADEE had reduced their DSN usage on 12/4/2013 and ACE was able to fit in 2 short passes. Santiago "range-only" certification tests began on Monday 12/2/2013. The first set of tests will be with Santiago's 9m antenna. The first test (12/2) had valid doppler data, but the range data off by 17,000km. The second test (12/3) had valid doppler and range data. The third test (12/6) appeared to have valid data, but is awaiting official word from FDF. A fourth test with Santiago's 9m antenna has been scheduled for 12/18/2013 in order to have 3 successful tests for the Near Earth Network's certification process. Tests of Santiago's 13m antenna will be performed in January 2014. ======================================================================== Anomalies: DOY 344 12/10/2013 S-ACE-0670 G13-0013 JPL Network Problems A problem with the JPL RPG firewall caused the MMOC to lose the network connection to JPL and DSS-27 for 21 minutes (1756-1817z). DR#N109241 IMPACT: Recorded science data was recovered after the network was restored. No real-time data to NOAA Space Weather Prediction Center for 21 minutes.
