Abstract

The Full-sky Astrometric Mapping Explorer (FAME) space mission will perform an all sky astrometric survey with unprecedented accuracy. FAME will produce an astrometric catalog of 40 million stars between 5th and 15th visual magnitude. For the bright stars (5th to 9th magnitude), FAME will determine the positions and parallaxes to better than 50 μas, with proper motion errors of 70 μas per year. For the fainter stars (between l0th and 15th magnitude), FAME will determine positions and parallaxes accurate to better than 500 μas with proper motions errors less than 500 μas per year. FAME will also collect photometric data on the 40 million stars. The accuracy of a single observation of a 9th magnitude star will be 1 mmag. The FAME mission will impact almost all areas of astrophysics. It will find planets revolving around nearby stars, further studies of stellar evolution, determine the location of dark matter in the Milky Way galaxy, and measure the size and age of the universe. It will also establish a celestial reference frame with an accuracy better than a microarcsecond.
