SIGNIFICANT EVENTS:

Executing Health and Safety (H&S)/Science Instrument (SI) Recovery SMS
SB190O00 (190/04:00Z - 190/22:00Z)

Recovery from Zero Gyro Sun Point (ZGSP) Safemode commenced @
189/14:41Z (OR 17218-2 with attached, red-lined Recovery from Zero
Gyro Procedure 7A). Transition from ZGSP to Software Sun Point
occurred @ 189/15:37Z. Aperture Door was opened @ 189/16:41Z.
Intercepted H&S load @ 190/04:00Z. Started SI recovery @ 190/07:00Z.
ZGSP recovery complete @ 190/03:43Z. Intercept Science SMS expected @
190/22:00Z.

Loaded RGA Scale Factor/Alignment and Gyro Bias Offset Tables (69 and
156) @ 189/14:55Z (OR 17215-3 with COP 3.48a, Section D, Steps D1 -
D5, D7, and D9 and ROP DF-1A). Dumped and compared Table 69 and 156.
No miscompares or missing data.

Performed ZGSP Recovery Coarse Attitude Determination @ 189/15:37Z (OR
17216 with COP 3.46).

Opened +DD SPA Trim Relay @ 189/17:52Z (OR 17213 with COP 4.22).

Enabled Magnetic Field Model Preview Mode @ 189/17:55Z (OR 17220 with
COP 3.53)

Fine Attitude Determination and Bias Calculation @ 189/19:06Z,
189/22:28Z, 190/00:11Z, 02:00Z, and 03:22Z (OR 17222). Uplinked
N02Z5260C and set ATP Pointer @ 190/02:29Z (OR 17223).

Cleared ACS and STIS Engineering Data Reports (MSAFINT1, MSAFINT3) @
189/17:57Z (OR 17219 with ROP NS-05). These reports were both set
upon ACS and STIS entry into safemode when vehicle entered ZGSP.
Reports need to be cleared prior to the start of SI recoveries in the
H&S SMS.
