2008 Progress
General
­ JWST has successfully completed its Non-Advocate Review and Confirmation Review processes and has been approved to begin the Implementation Phase ­ All observatory components, except for the spacecraft and membrane management system of the sunshield, have successfully completed their preliminary design reviews ­ All science instruments have successfully completed their critical design reviews

Telescope and Mirrors
­ All flight primary, secondary and tertiary mirrors have completed machining and are in various stages of rough polishing, smooth out and figure grinding ­ Mirror "Manufacturing Percentage" progressed from 41% to 55%

Observatory
­ Sunshield Preliminary Design Review held in February 2008 ­ Observatory Integration & Test control room opened at NGST

Ground Segment
­ Completed deliveries of all Science Instrument Integrated Test Sets (SITSs) and Science Instrument Development Units (SIDUs) to SI teams in the US, Canada and Europe
