The Sloan Digital Sky Survey V (SDSS-V) is pioneering panoptic spectroscopy.  SDSS-V consists of three separate large-scale surveys: 1) Black Hole Mapper (BHM) will trace the growth physics of black holes across the Universe, 2) Milky Way Mapper (MWM) is designed to decode the chemo-dynamical history of the Galaxy and investigate fundamental issues in stellar physics, and 3) the Local Volume Mapper (LVM) will increase our understanding of the self-regulation mechanisms of galactic ecosystems. BHM and MWM use wide-angle, fiber spectrographs to acquire optical (R ~ 2000, 500 fibers) and near-infrared (R ~ 22,000, 298 fibers) spectra at the 100-inch du Pont Telescope at Las Campanas Observatory and the 2.5-m Sloan Foundation Telescope at Apache Point Observatory.   The LVM performs ultra wide-field integral field spectroscopy across approximately 4300 sq deg in the Milky Way and the Magellanic Clouds, enabled by a new dedicated facility (LVM-I) at Las Campanas Observatory; the system employs an integral field unit with 1801 lenslet coupled fibers arranged in a hexagon of 0.25 degree diameter feeding multiple R=4000 optical spectrographs covering 3600-9800 A.
