James Webb Space Telescope Mirror's Amazing Anatomy
2014-03-20 15:02:51

Rob Gutro, NASA When you think of a mirror, there really isn't that much needed to describe it, but when you look at a mirror that will fly aboard NASA's next-generation James Webb Space Telescope, there's a lot to the anatomy of a mirror. NASA's Webb telescope includes a primary, secondary and tertiary mirror. Although the relatively small secondary and tertiary mirrors are unique, it's the expansive primary mirror that has the most complicated anatomy with a number of components...

In an important milestone for the Thirty Meter Telescope (TMT) project, Japan, one of the project's five international partners, has indicated its strong national backing for the next-generation astronomical observatory. On Wednesday, May 15, the Japanese parliament, known as the Diet, passed a fiscal year 2013 budget that includes key funding provisions 1244 million yen (approximately $12.2 million U.S.) for TMT, which contains TMT preparatory budget and a portion of Japan's TMT...

NASA Receives First Two Webb Mirrors

Lee Rannals for redOrbit.com — Your Universe Online NASA said on Monday that the first two of 18 primary mirrors for its James Webb Space Telescope have arrived at Goddard Space Flight Center in Greenbelt, Maryland. The mirrors are going through receiving and inspection, and will be stored in the Goddard cleanroom until engineers are ready to install them onto the telescope's backplane structure, according to the space agency. Ball Aerospace in Boulder, Colorado is building...

Tiny Planet-Finding Mirrors Borrow From Webb's Playbook

NASA's next flagship mission – the James Webb Space Telescope – will carry the largest primary mirror ever deployed. This segmented behemoth will unfold to 21.3 feet in diameter once the observatory reaches its orbit in 2018. A team of scientists at NASA's Goddard Space Flight Center in Greenbelt, Md., now is developing an instrument that would image and characterize planets beyond the solar system possibly from a high-altitude balloon has borrowed a page from the Webb...

When scientists are looking into space, the more they can see, the easier it is to piece together the puzzle of the cosmos. The James Webb Space Telescope's mirror blanks have now been constructed. When polished and assembled, together they will form a mirror whose area is over seven times larger than the Hubble Telescope's mirror. A telescope's sensitivity, or how much detail it can see, is directly related to the size of the mirror area that collects light from the cosmos. A larger area...
