ACE Weekly 03/04/2015 - 03/10/2015 ACE spacecraft subsystems are performing as expected. ======================================================================== Orbit/Attitude: Type Attitude Date 03/09/2015 DOY 068 2015 Thrusters 2R 4R+ 4R- Duration 8:52 min Start 22:17:52z Stop 22:26:44z ra,decStart 347.86,-19.95 ra,decStop 354.95,-16.00 ra,decExpect 355.52,-15.47 Deviation 0.76deg(-9%) HGAStart -8.19 deg HGAStop +8.73 deg SunStart 15.68 deg SunStop 12.71 deg SpinStart 5.0033 rpm SpinStop 5.0061 rpm Nutation 0.10 deg Firing 45 pulses FuelUsed 0.1417 lbm FuelRemain 100.0036 lbm FinalSCMass 1334.263 lbm 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. ======================================================================== OCRs: None ======================================================================== Activities: 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. ======================================================================== Anomalies: None
