SIGNIFICANT EVENTS:
Initial STIS telemetry after the first MAMA exposure indicates that the STIS MAMA Image Header Time 
Stamp issue (coarse time bits shifted-see HSTAR 13596) has cleared after the MIE FSW was reloaded 
(as part of the standard recovery sequence).  Steve A  From: Swain, Scott Sent: Wednesday, February 
20, 2013 5:55 PM To: List - Ops Flash Report Subject: SCI: *FLASH* Report -- Payload Recovery from 
DOY 046 SWSP  As of 051/22:52 UTC (5:52 pm EST this evening, 20 February), with the powering of the 
MAMA-2 detector on STIS, the recovery of the HST Payload from the SWSP safemode entry on DOY 046 
(15 February) has been completed.  Now that ACS, STIS, and COS have been recovered, temperatures in 
the Aft Shroud are returning to normal and the modified limits put in place after the SWSP entry 
may be restored.  All three instruments have all been successfully transitioned from Safe to their 
respective Operate states and are in varying  stages of recovering detectors and returning to 
normal science operations.  A timeline of the return to science activities was provided in the 
SH051X00 Delivery Letter, and is reproduced below for reference.  Items denoted with an "X" have 
been completed:       X     ACS  WFC  ~051/05:41 (internal)       X     ACS  WFC  ~051/12:40

~051/09:05 (external)  Many thanks to all those who contributed to the success of this recovery 
effort.  The SI SEs will also be monitoring the first STIS MAMA observations later this evening to 
assess the status of the MIE after its SWSP-induced reset.  If there are any questions or issues 
regarding this matter, please don't hesitate to contact me.  Thanks... Scott
