The James Webb Space Telescope full-scale model was on display at The International Society for Optical Engineering's (SPIE) week-long Astronomical Telescopes and Instrumentations conference during May 2006. The model is pictured at the end of a rainbow.

  Chile will close (i hope) be able to develop coated carbon fiber mirrors that will looks like yours (not with gold, but very smooth). And I'm very proud to contribute a little for such huge upcoming milestone!!!
