"Perfect" Mirrors Cast For LSST

Posted by kdawson on from the billion-pixels-of-goodness dept.

eldavojohn writes "The Large Synoptic Survey Telescope (which was partially funded by Gates & Co.) announced a world record casting for its single-piece primary and tertiary mirror blanks, cast at the University of Arizona. From the announcement: 'The Mirror Lab team opened the furnace for a close-up look at the cooled 51,900-pound mirror blank, which consists of an outer 27.5-foot diameter (8.4-meter) primary mirror and an inner 16.5-foot (5-meter) third mirror cast in one mold. It is the first time a combined primary and tertiary mirror has been produced on such a large scale.'"

    Apparently it was so awesome, they just skipped the secondary mirror and went straight to tertiary. :)

    I don't understand, what is this post about? It looks like random mindless babbling, not really a structured conspiracy theory or criticism or anything.

    Microsoft products aren't worth buying until they get to the third release. So they just skipped straight to #3 this time.
