The Origins Billion Star Survey (OBSS) is one of nine proposals recently selected by NASA for study as a future mission concept within NASA's Astronomical Search for Origins Program. The OBSS mission concept is a collaborative effort between USNO, JPL, IPAC, DTM, and U.Va aimed at providing a complete census of giant extrasolar planets for all types of stars in the galaxy and the demographics of stars within 10kpc. It will leave as a legacy the measurement of a billion stellar positions, parallaxes, proper motions, luminosities, binary determinations, photometry, spectroscopy and photometric variability. OBSS will be optimized for the detection of extrasolar giant planets as well as enabling an astrophysical characterization of all stars in the solar neighborhood.
