- last year showed progress with Engineering Unit

- this year  we have made excellent progress in telescope optics processing, the critical path on our schedule specifically the telescope optics.

- three stages of Be mirror polishing  (different from glass mirror)

- fabrication, lightweighting, polish (coarse and fine)

All of the Be telescope optics, including flight spares have been fabricated
