The Cullman mirror work was performed by a precision machine company now owned by General Dynamics but formerly known as Speed Ring and later as Axsys Technologies' Precision Machined Products division. The company is thought to be the world's expert in machining compounds containing the element beryllium.

The backplane is the last piece of Webb technology to be tested in Marshall's massive cold chamber. The facility has been dedicated to Webb testing for more than five years, and now that's finished. There are more tests of other technology scheduled next year, and there is the possibility of other new telescopes in the future, but the facility will also be available now to other government agencies needing its unique capabilities.

In space, any flex or movement could mean the telescope's mirrors can't be focused as scientists want. At 1 million miles away, far beyond the reach of repair, that could be a $9 billion disaster.

Axsys had an $18.6 million contract to build the 21 main mirrors and also the supporting mirrors for the telescope. It didn't polish the mirrors or add the now iconic gold coating, but it did build the basic mirror structure by grinding 400 pound pieces of beryllium compound down to mirrors weighing Adidas D Rose 773 3 Review less than 46 pounds each. The Cullman company shipped the last of the mirrors in 2008.

The James Webb Space Telescope is the world's next great observatory, successor to the Hubble Space Telescope, and the tool that scientists say will see stars formed sooner after the Big Bang than ever before and find new star systems being created. When it launches in 2018, Webb will be the $9 billion culmination of decades of dreams, design and construction.

Technicians started in September, but had to stop and warm the backplane back to room temperature when the federal government shutdown closed Adidas Basketball Rubber Shoes

On the Thursday before that Air Force flight takes off, the scaffold officially called the primary mirror backplane support sat under a plastic tarp in a giant clean room at Marshall's X Ray and Cryogenic Facility. There, the massive composite structure of more than 10,000 parts was subjected to cycles of temperature that can only be achieved in that facility and perhaps one other place for objects of its size.

How did the tests go when they finally resumed? "Really well," Kegley said. The structure will do its job in space, Marshall scientists believe.

Wonder if what you're planning to build can survive the environment of space? Marshall Space Flight Center has a really cold room the size of big boxcar that might have the answer.

To fulfill those dreams, Webb will rely on mirrors made in Cullman and a solar shield made in Huntsville. Almost all of its critical hardware was tested at Huntsville's Adidas Basketball Shoes D Rose 7

The company still working on Webb in Alabama is ManTech International subsidiary NeXolve in Huntsville. It is making the multi layered sunshield that will act like a tennis court sized beach umbrella to keep the telescope's sensitive electronics safe on the side exposed to the sun. See a video about the work below.

To do the tests, technicians from Marshall and contractor ATK attached 130 diodes to the backplane and ran the frame through several cycles from room temperature to minus 405 degrees Fahrenheit. Twenty six laser beams were used to measure positions during the tests.

Kegley and Helen Cole, project manager for Webb testing at Marshall, will watch next week's plane take off with "mixed emotions," Kegley said. "Glad it's over, glad to see everything moving along as it should," he said. "But it's like you've run off a cliff."

to fit inside the rocket that will launch them in 2018. That won't be an Alabama rocket, however, despite United Launch Alliance's rocket plant in Decatur or NASA's own Huntsville managed Michoud Assembly Facility outside New Orleans. Webb will lift off from French Guiana aboard an Ariane 5 ECA European rocket as part of Europe's contribution to the project.

"We were measuring the relative motion of key mounting points," facility test manager Jeff Kegley said Thursday as he looked down at the backplane. "To make sure they stay where they were supposed to."
