DAILY REPORT #3070
PERIOD COVERED: 0000Z (UTC) 03/11/02 – 0000Z (UTC) 03/12/02
Daily Status Report as of 071/0000Z
1.0 OBSERVATIONS SCHEDULED AND ACCOMPLISHED:
Science operations are scheduled to begin at approximately
071/0122Z, just after the period of this report.
2.0 FLIGHT OPERATIONS SUMMARY:
2.1 Guide Star Acquisitions:
Scheduled Acquisitions: 5
Successful: 5
Scheduled Re-acquisitions: 0
Successful: 0
2.2 FHST Updates:
Scheduled: 12
Successful: 12
2.3 Operations Notes:
All HST subsystems are reported to be in a nominal state. The
Science Instruments are all out of safe and awaiting resumption of
post-SM3B verification and normal science.
Per operations requests, the following actions were taken:
A gyro bias update at 070/1612Z.
An adjustment of SM3B limits at 070/1702Z.
An attitude reference update at 070/1830Z.
Gyro #6 was powered off at 070/2204Z. Gyro 6 limits were then
adjusted.
Using ROP DF-10A, a 486 safeware/table dump was made at 070/1715Z.
SSR-1 uncorrectable EDAC errors were cleared at 070/1934Z per ROP
SR-9A.
An engineering status buffer limit (SESBSLD=1) was modified at
071/0221Z, using ROP DF-18A.
At 071/025129Z, during a guide star acquisition, QSFGENB0 (Saved
FGS Error Null Bias 0) and QFGENB0 (FGS error null Bias 0) flagged
out-of-limits low. HSTAR 8548 was written.
As documented in HSTAR 8549, the NICMOS Cooling System CPL radiator
B temperature (MNCRADBT) flagged out-of-limits low with a value of -68.33 ,
the NICMOS Cooling System CPL Htex2 temperature (MNCHX1T) flagged low at
-63.33, and the NICMOS Cooling System CPL Radiator A temperature (MNCRADAT)
flagged low at -68.165. All occurrences were from 071/051558Z to 071/052748Z.
During the WF/PC-2 decontamination, the limits were managed at
071/0803Z per an operations note.
3.0 SIGNIFICANT FORTHCOMING EVENTS:
Commencement of Servicing Mission Orbital Verification (SMOV)
activities and the eventual continuation of normal science observations and
calibrations.
