SIGNIFICANT EVENTS:
The NSSC-1 BL/B! 9.2.0 FSW image was successfully transferred from the SSM486 via OR 19039-4 at
067/14:36 UTC. This was followed by a successful recovery of the NSSC-1 to Normal mode at
067/14:40 UTC.
The SIs have all been successfully recovered to their nominal Operate states following the
installation of the NSSC-1 BL/BQ 9.2.0 FSW image earlier this morning (with the exception of
NICMOS, which will continue to remain in Safe with TECs off).
Real-time commanding to recover both WFC3 and the ESM, NCS CPL, & PCE was successfully completed at
067/16:04 UTC and 067/17:10 UTC respectively. Stored commanding recovery transitions from the SMS
have been monitored since ~067/19:00 UTC through ~067/22:00 returning ACS, STIS, and COS, to their
nominal boundary states. WFC3 will be the first instrument to return to nominal science operations
with its first observation, scheduled for ~067/22:59 UTC. The ACS WFC will follow at ~068/00:05
UTC. STIS preparations for return to science will continue through the LV turn-on of both MAMAs,
which will complete tomorrow at ~068/15:00 UTC. COS is continuing to thermally stabilize before
resuming observations at ~068/22:39 UTC. Because the ACS SBC has been off for several months, the
068 SMS includes special commanding to perform a slow, full HV ramp-up (the final ramp-up from the
recovery from anomalous shutdown procedure) starting at 069/12:44 UTC. ACS Event Flag 2 in the
NSSC-1 has already been cleared to allow this commanding to execute. The ramp-up is followed two
days later by an SBC Fold Test, with the first nominal ramp-up commanding starting at 071/20:29 UTC.
