The manufacture of the JWST mirror blanks has now been completed.
Despite this milestone, the fate of JWST is still somewhat precarious, because although the scientific bang from the telescope is expected to be huge, the bucks required have increased to a staggering $4.5 billion. A Space.com article on the squeeze in NASA's space-based astronomy plans gives some background. The JWST home page can be found here. The Space Telescope Science Institute, which runs Hubble, also has a site here. As does ESA. |

That is a perfect display of the data and observation about it!
On the bright side, the longer that it takes to get JWST into space, the longer in the future before its operation ceases. One of its main purposes will be to observe exoplanets and more of them are being discovered through other means before JWST launches. It's entirely possible – even probable? – that the delays will end up providing some important opportunities for exoplanet science that would have been missed with earlier launch dates. |
