ACE Weekly 01/08/2014 - 01/15/2014 All ACE spacecraft subsystems are performing as expected. This weekly report covers 8 days in order to include the delayed maneuver on Wednesday 1/15. ======================================================================== Orbit/Attitude: Type Attitude SK-68 Date 01/15/2014 01/15/2014 DOY 015 2014 015 2014 Thrusters 2R 4R+ 4R- 3A 4A Duration 6:08 min 36.562 sec Start 13:31:44z 14:25:46 Stop 13:37:52z 14:26:24 HGAStart -9.02 deg +8.98 deg HGAStop +8.98 deg +8.97 deg SunStart 12.75 deg 11.70 deg SunStop 11.70 deg 11.70 deg SpinStart 4.9805 rpm 4.9815 rpm SpinStop 4.9815 rpm 4.9729 rpm Nutation 0.06 deg 0.03 deg Firing 31 pulses continuous FuelUsed 0.1030 lbm 0.1207 lbm FuelRemain 109.5408 lbm 109.4201 lbm FinalSCMass 1343.801 lbm 1343.680 lbm 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. ======================================================================== OCRs: DOY 010 (01/10/2014) 1420-1422z CRIS-011 2 cmds The Image Intensifier was powered on after being automatically safeguarded during the last week's solar activity (Wednesday 1/8/2014 09:18z, DOY 008). This OCR was last executed on 05/28/2013. ======================================================================== Activities: Data Capture: 99.99% DOY 005-012 2014 DOY 007 15:59:27-15:59:30 4 second gap while catching up on data DOY 007 17:02:48-17:02:51 4 second gap covered by ADC ADC format includes data from CRIS, EPAM, MAG, SIS, and SWEPAM-I but does not include data from SWICS, SWIMS, ULEIS and SWEPAM-E The Near Earth Network continues to performed range tests in order to analyze the range bias with the Flight Dynamics Facility. 01/09/2014 1830-1930z 9m Santiago 01/10/2014 1620-1710z 9m Santiago 01/13/2014 1750-1840z 13m Santiago 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. ======================================================================== Anomalies: None
