Successfully conducted March 9-12 at GSFC Major findings
Highly optimistic schedule which was not closing at the time of CDR
Resolved with new LRD of June 2014 SI flight deliveries not impacted by new LRD
Observatory thermal issues NGAS/GSFC has chosen a set of minimally invasive options
which result in radiator thermal performance margins above 50%
Options to further reduce IEC backloading are still being explored
Identify responsible person for each critical test Ongoing, accomplished as part of test planning
A total of 94 RFAs issued As of today:
52 responses submitted to the originator Of those, 29 have been closed

Status and Recent Progress - ASICs
Second flight run of ASICs is in processTeledyne 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 weekFirst 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
8 Mpix HgCdTe Focal Plane Assembly
Pathfinder Detector System testing is progressing wellDelivery to ESA scheduled for mid-July
Flight Detector System is awaiting delivery of flight ASICsScheduled for mid-November, supporting a Flight DS delivery of February 2010Evaluating options for ASIC common mode voltage requirement change
Plan to implement on the flight FPE prior to flight ASIC deliveryHave two high quality spare SCA candidates in-hand
Selection agreement with ESA pending
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 arraysMCE boards in testingFinal magnet motor deliveries from CDA imminent
Final shock requirements agreed to with Mission SystemsPlans envelope cryo and launch environmentsQualification testing at Astrium to begin next week

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

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
