... Technicians from Ball Aerospace and NASA at Marshall Space Flight Center's X-ray and Cryogenic Facility, of course, testing primary mirror segments of the James Webb Space Telescope (JWST). Scheduled for launch in 2014, JWST will be optimized for the infrared exploration of the early Universe, utilizing a primary mirror 21.3 feet across, composed of 18 hexagonal segments. Here, a group of JWST mirror segments are being prepared for tests to assure they meet the exacting mission requirements. ...

... October 4, 1999 . The 220 Mirrors of CRTF . ... Explanation: Even the largest of modern optical telescopes are small when compared with the light gathering power of the Central Receiver Test Facility (CRTF) located in New Mexico , USA. CRTF has 220 mirrors each over 7-meters in diameter all focused on a single tower. ... Recently, astronomers with the STACEE project have begun using CRTF to collect secondary light emitted when high-energy gamma rays strike the Earth's atmosphere. ...

... A three-cell test section roughly representative of the primary mirror was provided for this test by the Steward Mirror Lab. ... Additionally, the tests are intended to determine relative airflow vs. pressure drop characteristics for each of the air flow patterns so the results can be evaluated both as a function of flow rate and of pressure drop along the flow path. ... The bottom (top as installed) was cut out so it could close the chamber for heating and be removed for the cooling tests. ...

... Purpose: The purpose of this test is to determine the degree to which the COSTAR mirrors have reduced the throughput of the GHRS, particularly at wavelengths below Lyman-alpha. ... However, the usual series of wavelengths on both Side 1 and Side 2 will be observed so that this program is also a sensitivity monitor close-out. ... This test will execute once only during Cycle 6, at the end of the Cycle. ... Also, we will need to carefully consider how these new data compare to older sensitivity tests....
