DESCRIPTION:The Maunakea Spectroscopic Explorer (MSE) is a planned 11-m te
 lescope designed to fill what is the most obvious missing link in the emer
 ging network of international multi-wavelength facilities\; namely\, fully
  dedicated\, large aperture\, highly multiplexed spectroscopy at a range o
 f spectral resolutions in the optical and near infrared wavelength range. 
  It will be completely dedicated to multi-object spectroscopy of samples o
 f between thousands and millions of astrophysical objects. It will lead th
 e world in this arena\, due to its unique design capabilities: it will boa
 st a large (11.25 m) aperture and wide (1.52 sq. degree) field of view\; i
 t will observe at a wide range of spectral resolutions\, from R2500 to R40
 \,000\, with massive multiplexing (4\,332 spectra per exposure\, with all 
 spectral resolutions available at all times). In total\, more than 10 mill
 ion fiber hours of 10-m class spectroscopy will be available for forefront
  science every year. With these unrivalled capabilities\, MSE will unveil 
 the composition and dynamics of the faint Universe and impact nearly every
  field of astrophysics across all spatial scales\, from individual stars t
 o the largest scale structures in the Universe. Major pillars in the scien
 ce program for MSE include (i) the ulitimate Gaia follow-up facility for u
 nderstanding the chemistry and dynamics of the distant Milky Way\, includi
 ng the outer disk and faint stellar halo at high spectral resolution (ii) 
 galaxy formation and evolution at cosmic noon\, via the type of revolution
 ary surveys that have occurred in the nearby Universe\, but now conducted 
 at the peak of the star formation history of the Universe (iii) derivation
  of the mass of the neutrino and insights into inflationary physics throug
 h a cosmological redshift survey that probes a large volume of the Univers
 e with a high galaxy density. MSE naturally complements and extends the sc
 ientific power of Gaia\, the Large Synoptic Survey Telescope\, the Square 
 Kilometer Array\, Euclid\, WFIRST\, the 30m telescopes and many more. I wi
 ll present a broad overview of MSE\,  including the key science\, the curr
 ent design status\, as well as the international partnership\, and highlig
 ht numerous opportunities for engagement in the ongoing scientific and tec
 hnical development of this next generation observatory.\n\n
