The Joint Milli-Arcsecond Pathfinder Survey (JMAPS): Introduction and Science Possibilities
Abstract
JMAPS is a small, space-based, all-sky visible wavelength astrometric and photometric survey mission for oth through 14th V-band magnitude stars with a 2012 launch. The primary objective of the JMAPS mission is the generation of an astrometric star catalog with better than 1 milliarcsecond positional accuracy and photometry to the 1% accuracy level or better at 1st to 12th mag. A I-mas all-sky survey will have a significant impact on our current understanding of galactic and stellar astrophysics. JMAPS will improve our understanding of the origins of nearby young stars, provide insight into the dynamics of star formation regions and associations, investigate the dynamics and membership of nearby open clusters, and discover the smallest brown dwarfs at distances up to 5 pc after a 2-year mission, and Jupiter-like planets out to 3 pc after 4 years.
