The Milli-Arcsecond Pathfinder Survey (MAPS) mission is a space-based, all-sky, visible wavelength astrometric and photometric survey for 2nd through 15th magnitude stars with a 2012 launch date goal. The primary mission goal for MAPS is the generation of a 1-milliarcsecond (mas) all-sky astrometric catalog for bright stars. The instrument consists of a 15-cm telescope, a large (64 megapixel) CMOS-hybrid detector, associated processing electronics, and is carried aboard a microsatellite bus in a 900-km, sun-synchronous, low Earth orbit. The status of the MAPS mission will be reviewed, including current risk reduction activities. A 1-mas (or better) all-sky survey through approximately 15th magnitude will have a significant impact on our current understanding of galactic and stellar astrophysics. In particular, the combination of the MAPS and Hipparcos catalogs will produce common proper motions on the order of 0.1 mas/yr level.
