US-SPACE-WEBB TELESCOPE
This NASA photo received 30 August, 2007 shows a Ball Aerospace & Technologies Corp technician working with fully functional, 1/6th scale model of the mirror on the James Webb Space Telescope (JWST) during tests of the software that will control the 18 mirror segments that must be aligned so that they act as one smooth surface. The James Webb Telescope will be a large infrared telescope with a 6.5-meter primary mirror. Launch is planned for 2013. With a combined mirror surface of 269 square feet (25 square meters), the Webb telescope will have nearly six times the light-gathering ability of the Hubble Telescope, which has one giant 46-square-foot (4.3-square-meter) mirror. Astronomers expect such sensitivity to allow them to see the first stars and galaxies of the universe as well as young planetary systems. AFP PHOTO/HO/NASA /Northrup Grumman /Ball Aerospace GETTY OUT
