BOSS will employ an upgraded version of the SDSS fiber-fed spectrographs to map the redshifts of 1.5 million Luminous Red Galaxies (LRGs) out to z~0.7 over 10,000 square degrees, measuring the BAO signal in the large-scale galaxy correlations. A simultaneous survey of z~2.5 quasars (using 20% of the fibers) will allow us to measure the acoustic oscillations in the correlations of the Lyman-alpha forest.
