ESA's Gaia mission, now entering its second year of routine science operations, will soon fulfil its promise for revolutionary science in the countless aspects of Galactic astronomy and astrophysics. I will briefly review the Gaia mission status of operations, and the scenario for intermediate data releases. Iwill then illustrate the potential of µas astrometry for detection and improved characterization of planetary systems in the neighborhood of the Sun. <P />ELETTRONICOenConference abstracthttps://www.epsc2015.eu/2015EPSC...10..907SFIS/05 - ASTRONOMIA E ASTROFISICAScienze Fisiche Settori ERC (ERC) di riferimento::PE9 Universe sciences: astro-physics/chemistry/biology; solar systems; stellar, galactic and extragalactic astronomy, planetary systems, cosmology, space science, instrumentation
