Waspie_Dwarf Posted November 26, 2015 #1 Share Posted November 26, 2015 NASA’s Webb Space Telescope Receives First Mirror Installation NASA has successfully installed the first of 18 flight mirrors onto the James Webb Space Telescope, beginning a critical piece of the observatory’s construction.In the clean room at NASA’s Goddard Space Flight Center in Greenbelt, Maryland this week, the engineering team used a robot arm to lift and lower the hexagonal-shaped segment that measures just over 4.2 feet (1.3 meters) across and weighs approximately 88 pounds (40 kilograms). After being pieced together, the 18 primary mirror segments will work together as one large 21.3-foot (6.5-meter) mirror. The full installation is expected to be complete early next year.

Waspie_Dwarf Posted November 30, 2015 Author #3 Share Posted November 30, 2015 NASA's Webb "Pathfinder Telescope" Successfully Completes Second Super-Cold Optical Test Recently, the James Webb Space Telescope's "pathfinder telescope," or “Pathfinder” completed its second super-cold optical test that resulted in the first checkout of specialized optical test equipment designed to illuminate the telescope’s optics through to the instrument focal planes, and the procedures used to operate this test equipment.While the actual flight elements of NASA's Webb telescope are assembled, engineers are testing the non-flight equipment installed in the test chamber to ensure that tests on the real Webb telescope later go safely and according to plan.

Waspie_Dwarf Posted December 31, 2015 Author #4 Share Posted December 31, 2015 James Webb Space Telescope Mirror Halfway Complete Inside NASA's Goddard Space Flight Center's massive clean room in Greenbelt, Maryland, the ninth flight mirror was installed onto the telescope structure with a robotic arm. This marks the halfway completion point for the James Webb Space Telescope's segmented primary mirror.The James Webb Space Telescope team has been working tirelessly to install all 18 of Webb's mirror segments onto the telescope structure.

Waspie_Dwarf Posted January 7, 2016 Author #5 Share Posted January 7, 2016 By the Dozen: NASA's James Webb Space Telescope Mirrors One dozen flight mirrors are now installed on NASA's James Webb Space Telescope, out of the eighteen mirror segments that make up the primary mirror. The assembly of the primary mirror is an important milestone for the Webb telescope, but is just one component of this huge and complex observatory.Since December 2015, the team of scientists and engineers have been working tirelessly to install all the primary mirror segments onto the telescope structure in the large clean room at NASA's Goddard Space Flight Center in Greenbelt, Maryland. The twelfth mirror was installed on January 2, 2016. Read more... 1 Link to comment Share on other sites More sharing options...
Waspie_Dwarf Posted February 4, 2016 Author #6 Share Posted February 4, 2016 NASA's James Webb Space Telescope Primary Mirror Fully Assembled The 18th and final primary mirror segment is installed on what will be the biggest and most powerful space telescope ever launched. The final mirror installation Wednesday at NASA’s Goddard Space Flight Center in Greenbelt, Maryland marks an important milestone in the assembly of the agency’s James Webb Space Telescope.“Scientists and engineers have been working tirelessly to install these incredible, nearly perfect mirrors that will focus light from previously hidden realms of planetary atmospheres, star forming regions and the very beginnings of the Universe,” said John Grunsfeld, associate administrator for NASA’s Science Mission Directorate in Washington. “With the mirrors finally complete, we are one step closer to the audacious observations that will unravel the mysteries of the Universe.” Read more...

Waspie_Dwarf Posted March 8, 2016 Author #7 Share Posted March 8, 2016 NASA's James Webb Space Telescope Secondary Mirror Installed The sole secondary mirror that will fly aboard NASA's James Webb Space Telescope was installed onto the telescope at NASA's Goddard Space Flight Center in Greenbelt, Maryland, on March 3, 2016.The Webb telescope uses many mirrors to direct incoming light into the telescope's instruments. The secondary mirror is called the secondary mirror because it is the second surface the light from the cosmos hits on its route into the telescope.

Waspie_Dwarf Posted March 21, 2016 Author #9 Share Posted March 21, 2016 NASA Marks Major Milestones for the James Webb Space Telescope NASA's James Webb Space Telescope just got a little closer to launch with the completion of cryogenic testing on its science cameras and spectrographs and the installation of the final flight mirrors.After over a year of planning, nearly four months of final cryo (cold) testing and monitoring, the testing on the science instruments module of the observatory was completed. They were removed from a giant thermal vacuum chamber at NASA's Goddard Space Flight Center in Greenbelt, Maryland called the Space Environment Simulator, or SES, that duplicates the vacuum and extreme temperatures of space. The SES is a 40-foot-tall, 27-foot-diameter cylindrical chamber that eliminates almost all of the air with vacuum pumps and uses liquid nitrogen and even colder gaseous helium to drop the temperature.
