Ball Aerospace lead optical test engineer Dave Chaney inspects six primary mirror segments, critical elements of NASA's James Webb Space Telescope, prior to cryogenic testing in the X-ray & Cryogenic Facility at NASA's Marshall Space Flight Center in Huntsville, Ala. The James Webb Space Telescope will be launched in 2014 to study the formation of the first stars and galaxies and shed new light on the evolution of the universe.
