MIRI EC Meeting C/D13, Dublin, 17 th to 19 th September JWST Status

MIRI EC Meeting C/D13, Dublin, 17 th to 19 th September JWST Mission Status Across the whole observatory there is now -A lot of FM hardware in production -Many good test results at observatory subassembly level (the other instruments, mirror backplane, ISIM structure.....) -Some not so good test results and “issues in work” -So much like us Overall schedule to launch date is still being held -Test programme is starting to stabilise Following successful Non-Advocate Review NASA is fully committed to JWST -There is now a very large team at both GSFC and NGST -Peak years of engineering effort and cost are now and next year !. First Flight Mirrors are about to start testing (after polishing)

MIRI EC Meeting C/D13, Dublin, 17 th to 19 th September Technical Areas Currently Getting a Lot of Attention Sunshade deployment -A special review is planned to ensure problems have been solved (tightness of edges of sunshade affect efficiency) Alignment of instruments to the (ISIM and) telescope and of telescope itself -A lot of work in this area, extremely tight tolerances (microns over meters) -Detailed review of OGSE about to start. -MIRI pupil lens will be used in for in-flight measurement of pupil shear to eliminate a possible redundancy in the alignment algorithms Cooler Heat Loads Margins -End to end review of current margin in all areas Electrical Power budget for mission - more power to the Cooler ;-) (among many changes) Test Plans and Verification at Observatory Level Really big focus across the board on pushing every schedule in order to get the Observatory (FM) into end-end cryo-test as soon as possible.

MIRI EC Meeting C/D13, Dublin, 17 th to 19 th September Operations Progress and Planning (wrt MIRI) MIRI Proposal Planning System Template Definitions -Draft specifications are in work Cross Instrument Calibration Working Group Set up -Karl Gordon is MIRI member, looking for commonalities between instruments (dark current subtraction). Operations Script Development is making good progress -Plan to test at RAL at the end of VM2

MIRI EC Meeting C/D13, Dublin, 17 th to 19 th September JWST Science Working Group Activities A specialist working group has been set up to consider how we can best observe planetary transits -Identify if special observatory modes are needed. A study is on-going to write a paper explaining the impact to science if the telescope image quality specification were to be relaxed (eg diffraction limited at 3um) -Very bad impacts for NIRCAM and NIRSPEC sensitivity -At the moment this is a “just in case” activity -In case the mirror cryo-polish cycles are too difficult (impossible) -There is no mission plan to actually do this. Plan is to make a serious announcement to community of process for selecting first observations at the AAS meeting in January 2009.
