FAME (S00-5)

FAME (MIDEX 4) [NASA]

FAME (Full-sky Astrometric Mapping Explorer) is a space astrometry mission that measures the positions, proper motions, parallaxes, and photometry of 40,000,000 stars brighter than V=15th magnitude to between 50 and 500 microarcseconds accuracy, depending on the magnitude.

It was selected as a MIDEX Explorer mission by NASA, but NASA cancelled its support for this mission due to doubts, if the goals could be reached.
