James Webb Space Telescope marks successful completion
Date:12/3/2007

GREENBELT, Md. A preliminary design review has concluded and verified the integrated performance of all subsystems in the Optical Telescope Element on NASAs James Webb Space Telescope.

The Optical Telescope Element or OTE is the "eye" of the Webb Observatory. The telescope consists of a 6.5-meter (21.3 foot) primary mirror; secondary, tertiary and fine steering mirrors; and supporting structures, deployable tower and control electronics.

"The successful completion of the Optical Telescope Element Preliminary Design Review is a significant milestone in the telescope development which demonstrates it's full feasibility and which allows the team to move on to final, detailed designs," said Lee Feinberg, James Webb Space Telescope Optical Telescope Element Manager at NASA's Goddard Space Flight Center, Greenbelt, Md.

"Meeting rigorous technology development requirements and successfully completing component design reviews earlier this year have given us confidence that the telescope will perform its mission within our cost and schedule commitments," said Martin Mohan, JWST program manager for Northrop Grummans Space Technology sector. Northrop Grumman is NASAs prime contactor for the Webb Telescope, leading the design and development effort under contract to NASA Goddard.

Last January, before a team of experts assembled by NASA, the Northrop Grumman the telescope team demonstrated that the technology ready to move into the detailed engineering phase. Technology Readiness Level 6 was achieved for all critical telescope components, meaning prototypes had been successfully tested in a thermal vacuum chamber. The thermal vacuum simulates the very cold temperatures and vacuum of space.

At the review, the team also presented a plan for the final assembly and verification of the telescope. This includes all subsystems, backplane, thermal controls and hardware for sub-assemblies as well as simulated space environment testing at Johnson Space Center, Houston.

Significant progress is being made on key portions of the telescope. Machining of the 18 primary mirror flight segments was completed earlier this year and currently the backplane, which supports the primary mirror, is being fabricated.

The Webb Telescope will be the premier space observatory of the next decade, serving thousands of astronomers worldwide. It will study every phase in the history of our universe, from the first galaxies assembled in the universe, to the formation of solar systems potentially capable of supporting life, to the evolution of our own Solar System.
