Abstract: MSE is a project to replace the current 3.6 m CFHT with a 10 m class, segmented, wide-field telescope that will feed a dedicated suite of multi-object spectrographs, operating at resolutions from R∼2000 to R>20000, and obtaining >3000 spectra per pointing (>> 5 million spectra/yr). It will use much of the existing infrastructure of the current CFHT, including the pier, and will closely approximate the envelope of the existing facility. MSE will be the only fully dedicated, 10 m class, wide-field spectroscopic telescope at first light in ∼ 2025. It will fill arguably the single biggest “missing link” in the international network of astronomical facilities. At optical wavelengths, LSST, WFIRST, Euclid, and Gaia will identify many millions of astrophysically interesting targets that otherwise lack the dedicated, large aperture, spectroscopic followup facilities required to probe their chemodynamical properties. Elsewhere, SKA, eRosita and others will provide a revolution in our understanding of the multiwavelength Universe. Among this capability, MSE will be an essential tool by providing the optical data that will otherwise be chronically absent.
