NASA’s James Webb Space Telescope: A Year of Achievement and Success

The James Webb Space Telescope marked a year of significant progress in 2011 as it continues to come together as NASA’s next generation space telescope. The year brought forth a pathfinder backplane to support the large primary mirror structure, mirror cryotesting, creation of mirror support structures, several successful sunshield layer tests and the creation of an assembly station within NASA Goddard Space Flight Center’s cleanroom. Achievements were also made in the areas of flight and communications software and the propulsion system. In December, manufacturing and testing of all flight mirrors was completed in a final test at the X-ray and Calibration Facility at Marshall Space Flight Center, Huntsville, Ala. During these tests mirror segments were chilled to temperatures similar to those Webb will see in space, around minus 400 degrees Fahrenheit. Read more
