Interview: Webb Space Telescope Mirrors
The James Webb Space Telescope features a mirror 21.3 feet across that consists of 18 separate, hexagon-shaped mirrors. The mirror components are being tested both individually and together. A specially designed vacuum chamber at Marshall Space Flight Center simulates the extreme conditions of spa, subjecting the mirror segments to temperatures as low as 400 degrees below zero.  credit: NASA
