The M3/M1 mirror surfaces were accepted as a critical component of the LSST or Large Synoptic Survey Telescope project, this past week, according to the LSST project office. These mirror surfaces represent cutting edge technology in improving the reflective surface of telescope mirrors, and were accepted to the project without qualification after an intensive testing period. Led by researchers at CIERA, Northwestern is an institution member of the LSST, which is effort to build a next-generation ground-based telescope. Congratulations to all!
