Previously completed step 8 of SOP56003, Safe Mode Recovery to A-Side Equipment. This uplinks SCS141 to establish NSM as part of regaining PCAD control to OBC from CPE. Tonight's plan: (2) do steps 9-18 of SOP56003. ~1-1/2 hr. (3) steps 19-33,35,36,38,39 PCAD +CAPs ~1-1/2 hr. Tomorrow morning plan: (4) Fine attitude init. CAP456a is being written tonight, will be executed Fri AM ~3 hr. (5) SI prep+observ ~2 hr. EVENTS (times are approx.)

Done via CAP. Expect a CAP during SI enables tomorrow to turn this IRU off. (3) The above modification of the script caused an improper ordering of the update to ephemeris time and activation of the Commanded Attitude Monitor. This resulted in a trip of the CAM and generated an OBC error, but did NOT actually trip the resulting safing actions based on the way the trip was generated. There turned out to be no significant detrimental effects from this error except time lost to traceback. SCS 38 and SCS 28 were disabled (both related to the CAM and resulting safing) to protect the spacecraft from inadvertant safing actions during investigation and will need to be reactivated during Fine Attitude Init. in the morning. (4) We did perform step 37 of SOP 56003 since at a post-briefing update it was shown that this is just a patch upload and does not involve moving the SIM as previously stated. It merely prepares the SIM for later commanding.
