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. |

There's been an interruption in the function of the NIRISS instrument on the JWST. The updates have been few and probably reflect a lack of certainty on the ground. A loss of that instrument would entail a serious loss of science, but this last update makes it sound like the team is optimistic pending more information.

NIRISS is back online. This update doesn't say much about the cause of the glitch, but it must not have involved hardware in any serious way.
