04.11.11 - Goddard's Sunday Experiment this month features eye-opening, hands-on activities spotlighting Hubble's successor, the James Webb Space Telescope.
09.28.10 - NASA engineers have created a unique engineering marvel called the ISIM structure that recently survived exposure to extreme cryogenic temperatures, proving that the structure will remain stable when exposed to the harsh environment of space.
09.09.10 - The Marshall Center's X-ray & Cryogenic Facility has received a unique James Webb Space Telescope element for testing.
07.27.10 - Recently, six James Webb Space Telescope beryllium mirror segments completed a series of cryogenic tests at the X-ray & Cryogenic Facility at the Marshall Center.
07.15.10 - NASA recently recognized the late Dr. Timothy Hawarden for his work on cooling techniques for infrared space telescopes, including the James Webb Space Telescope.
04.13.10 - NASA Administrator Charles Bolden listens as Dave Chaney explains how the James Webb Space Telescope mirror segments are tested in the X-ray and Cryogenic Facility, or XRCF.
03.30.10 - The cosmos is filled with color, and color is a key in determining age, chemical composition and how far objects are from Earth. To help identify these colors and objects the James Webb Space Telescope will be using a spectrograph called NIRSpec.
03.02.10 - The James Webb Space Telescope reached a mission-readiness landmark today when its first primary mirror segment was cryo-polished to its required prescription as measured at operational cryogenic temperatures.
02.02.10 - The James Webb Space Telescope's five-layer, tennis court sized sunshield has passed its critical design review, certifying that its design is complete and meets mission requirements.
