  The NEAT (Nearby Earth Astrometric Telescope) mission is a proposal submitted
to ESA for its 2010 call for M-size mission within the Cosmic Vision 2015-2025
plan. The main scientific goal of the NEAT mission is to detect and
characterize planetary systems in an exhaustive way down to 1 Earth mass in the
habitable zone and further away, around nearby stars for F, G, and K spectral
types. This survey would provide the actual planetary masses, the full
characterization of the orbits including their inclination, for all the
components of the planetary system down to that mass limit. NEAT will continue
the work performed by Hipparcos and Gaia by reaching a precision that is
improved by two orders of magnitude on pointed targets.
