Project Status (continued) § Remaining Major 2009 events: Ø ISIM flight structure delivery to the GSFC from ATK in August Ø MIRI flight Focal Plane system delivery to RAL in August (TBR) Ø Sunshield 1/3 Scale Test Readiness Review (TRR) in August at NGAS Ø Spacecraft Bus PDR, July 28 -30 at NGAS Ø Cryo Cooler CDR in June at NGAS Ø Flight NIRSpec Micro Shutter system delivery to ESA in September Ø Modified Pathfinder NIRSpec Detector system delivery to ESA July Ø Optical Telescope Element CDR scheduled for October at NGAS Ø Sun Shield CDR scheduled for November at NGAS § Mission Critical Design Review in March 2010 at the GSFC 16
Worry List § § Cost increases Late ISIM deliveries Low cost reserves Problematic use of the Space Cargo Transporter System (SCTS) – The project has included costs for a JWST unique shipping container in this year’s budget – Working with NGAS and Arianespace on requirements § NIRCam Wave Front Error – Proceeding with the redesigned bonded lens mount design - Review held on May 14 th – Developed a new alignment plan, which allows for greater accuracy both during build up and at the module level § Meeting Cryo Cooler allocations with required margins § § – Baselined MIRI shield – Concept review held last week Microshutter shock survivability – Qualification unit over tested and failed – Established new testing approach and levels – Testing currently underway at Astrium Rebuilt ASIC cost and schedule – New ASIC’s will be ready in the November 2009 to March 2010 timeframe MIRI FPE noise issues Primary Mirror A 1 actuator gear motor failure 17
