SMOV Status & Planning Meeting Notes
7/10/09
-
-
Summary: STIS suspended (reference HSTAR 11922) at 190/06:19 UTC during the
procedure to recover to Operate and dump the MIE memory. An intercept SMS, removing all
STIS commanding for the remainder of the 187 SMS, was produced and uplinked last night.
NOTE: After the meeting, STIS was recovered to Operate, but then suspended on the
same MIE dump test as yesterday (HSTAR 11927). SMS194 was reworked to remove
all STIS activities from the week. An ARB will likely be convened next week.
-
After analyis, it is expected that WFC3 IR alignment will be confirmed. The need for any
further adjustment to the UVIS alignment mechanism, which is showing some non-linearity, is
still under discussion (but UVIS SMOV can proceed.). COS aperture mechanism
commanding used in the NUV alignment activity has been corrected and the visits reinserted
into the near-term schedule. The intercept SMS needed to accommodate both the need for a
realtime STIS recovery and the opportunity to repeat the COS visits with updated aperture
mechanism commandinghas been generated and uplinked. ACS internals are proceeding
nominally.
-
Plans are proceeding to restart the NICMOS Cooling System next week. (Last night the CPL
was restarted.)

Science. TKeyes
 NUV Optical Alignment (COS09, 11469)
o Visit 7 - Anomalous aperture mechanism behavior (reported
yesterday)
 Cause of the anomalous behavior was traced to
exposure routines that command the aperture mech
to home, thereby undoing the relative moves
commanded just prior to the start of the exposure
routine.
 Exposure routines have been modified to avoid the
home commands
 Visits have been inserted into the 187
Intercept SMS
