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. |

Based on Cassini's monitoring, it seems that it rains on any given location on Titan only once in several decades or centuries, although when it does, the volume is extremely heavy. Despite Titan's 100% coverage in haze, the presence of clouds like these is quite rare at any given place and time. Preparing a future mission for rain seems to be like preparing a mission to Earth for hurricanes.
