One of the most challenging parts of NASA’s huge new space telescope, the building of its ultrasophisticated mirror system, is now finished, and the mirrors are ready for delivery.
Send-off ceremonies held here at Ball Aerospace on Aug. 15 saluted the completion of 18 beryllium primary mirror segments for the James Webb Space Telescope (JWST), which is billed as the successor to NASA's venerable Hubble Space Telescope. Ball is also responsible for JWST’s secondary and tertiary mirrors, a fine steering mirror assembly and several engineering development units.
Ball is the principal subcontractor to manufacturer Northrop Grumman for the JWST optical technology and lightweight mirror system at the heart of the telescope — an astronomical project that is now pegged to cost roughly $8.7 billion and to be lofted in the fall of 2018.
