Summary

DescriptionJames Webb Space Telescope Mirror38.jpg	English: Six of the 18 Webb telescope mirrors are readied for shipment. All of the 18 mirror segments will be cryogenically tested twice in the Marshall Center's X-ray & Cryogenic Facility -- once with bare polished beryllium and then again after a thin coating of gold is applied to gain optimal reflectance in the infrared.
