4. Status and Recent Progress - ASICs • Second flight run of ASICs is in process • Teledyne is making excellent progress finalizing the production details, and is working to a schedule that supports deliveries to flight instrument teams beginning this November • Pathfinder units begin assembly this week • First flight article builds beginning in July • Have determined that the minimum common mode voltage requirement needs to be increased • Instrument teams notified, design modifications are in process

5. Status and Recent Progress – NIRSpec Detectors • Pathfinder Detector System testing is progressing well • Delivery to ESA scheduled for mid-July • Flight Detector System is awaiting delivery of flight ASICs • Scheduled for mid-November, supporting a Flight DS delivery of February 2010 • Evaluating options for ASIC common mode voltage requirement change • Plan to implement on the flight FPE prior to flight ASIC delivery • Have two high quality spare SCA candidates in-hand • Selection agreement with ESA pending 8 Mpix HgCdTe Focal Plane Assembly Focal Plane Assembly (FPA)

Status and Recent Progress - Microshutters • Flight Microshutter System integration is in progress and on track for September delivery to ESA • Selected flight arrays • MCE boards in testing • Final magnet motor deliveries from CDA imminent • Final shock requirements agreed to with Mission Systems • Plans envelope cryo and launch environments • Qualification testing at Astrium to begin next week Microshutter Array

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 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 ICDH IRSU

10. Status and Recent Progress – ISIM Software and ITSS • 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 • 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. Integration of the prototype baffle test unit completed and the first unit is being tested. Status and Recent Progress – ISIM Electronics Compartment 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
