A schematic representation of SDSS-V: an all-sky, multiepoch spectroscopic facility and its science programs. Dual-hemisphere survey operations are undertaken at APO and LCO. Multiobject fiber spectroscopy is being carried out with two 2.5 m telescopes, each feeding a near-IR APOGEE spectrograph (300 fibers, R ∼ 22,000) and an optical BOSS spectrograph (500 fibers, R ∼ 2000). This enables a sky survey rate of ≳ 25 deg2 hr−1. Ultra–wide-field integral field spectroscopy is being carried out by the LVM-I at LCO using a smaller 0.16 m telescope, with a ∼2000-fiber IFU feeding three optical R ∼ 4000 spectrographs. This schematic also outlines the three primary science programs: the MWM (red), drawing on both APOGEE (red) and BOSS (yellow) spectra; the BHM (orange), taking BOSS spectra of fainter targets; and the LVM (green), performing IFU mapping of the ionized ISM in the MW and nearby galaxies (image credit: M.
