7 Status and Recent Progress – ISIM Harness Radiator  Critical Design Review scheduled for June 15 at GSFC  Had been postponed due to interface loads issues, which have been resolved  Incorporation of a spherical bearing assembly reduced loads and simplified integration with the backplane  Most drawings complete and out for quote  Working toward December delivery

8 Status and Recent Progress – Harness  Have shipped over 150 harness assemblies in support of  Instrument ETU and flight builds  EGSE (SITS, etc…)  ISIM integration and test preparations  Held a successful NIRSpec Detector Harness Manufacturing Readiness Review on May 5, 2009  Tayco has improved the application and control of the potting where the cable meets the backshell

9 Status and Recent Progress – ICDH and IRSU ICDH  ICDH ETU I&T scheduled to complete in June  Support of instrument thread testing and FSW development will continue  Helping out GLORY…  Failure of their flight spacecraft computer boards has jeopardized the January 2010 launch date  JWST flight assets will be utilized, and can be implemented in time to preserve GLORY’s schedule  Resultant 3 month impact to ISIM ICDH can be absorbed  IRSU Protoflight boards build in process  Box level I&T to begin in September IRSU

10  Flight Software  Build IC11 testing to begin next month  NIRSpec MSS FSW  Began development of MSS C4.1 (final build)  NIRSpec DS FSW has transitioned into “maintenance” mode Status and Recent Progress – ISIM Software and ITSS  ITSS  Focus is now shifting to:  Build and test of the Certification Lab at GSFC for ISIM I&T  Build and test of ISIM Electrical Simulators for testbeds at Northrop Grumman  Continuing to support systems in the field in maintenance mode  Continuing to support instrument interface testing

11 Status and Recent Progress – ISIM Electronics Compartment Integration of the prototype baffle test unit completed and the first unit is being tested. The first cure cycle of the IEC shell is complete. Co-cure inserts and final fiberglass layer fabrication begins in the first week of May. Inserts ready for installation
