[1771](/occweb/web/webapps/ifot/ifot.php?r=flightops&t=properties&format=sheet&id=950633) | 012/2029z | LETG Diagnostic Manual Insert The LETG insertion on day 2025:012 failed due to the Insert microswitch not reading INSR at the end of the move. Without this positive indication of LETG insertion, OTG FSW cannot be used to retract the grating. A manual insertion will be commanded using timed SCSs to execute the motions as a diagnostic attempt to get the Insert Microswitch to engage and stay engaged. [1772](/occweb/web/webapps/ifot/ifot.php?r=flightops&t=properties&format=sheet&id=950640) | 013/0020z | Reset Last Move Success Flag and Retract LETG If an OTG motion fails for any reason the Last_Sequence_Successful flag is set to False to inhibit future OTG motions. To re-enable OTG motions after the initial OTG motion error is corrected; the Last_Sequence_Sucessful flag must be reset to True. After the Last_Sequence_Successful is reset, a software retraction of the LETG will be commanded so that the final conditions can be verified in realtime. Radiation: Solar activity is expected to be low with a chance for M-class flares and a slight chance for an X-class flare on days one, two, and three (13 Jan, 14 Jan, 15 Jan). MP: JAN1425 Return-to-Science loads out for review. ENG: LETG insertion issues on Saturday night. Ran through all allowed short moves, but failed to trigger insert microswitch. SCS 107 manually activated to safe instruments and stop loads. Also ran CAP 1772 to clear failed move flag. Flag cleared up but retration not performed due to glitch in OBC with forthcoming patch. Reasoning behind failure of microswitch triggering still in investigation. GOT: No issues.
