Abstract

Gaia is an all-sky survey satellite, to be launched by ESA in late 2011, to obtain parallaxes and proper motions to microarcsecond precision, radial velocities and astrophysical parameters for about 109 objects down to a limiting magnitude of 20mag, which means about 104 times more stars than observed with Hipparcos mission. The astrophysical information for all sources will be derived from broad-band photometry and low-resolution spectrophotometry complemented with astrometric and high-resolution spectroscopy measurements around CaII triplet. This paper describes the instrument and its capabilities in terms of stellar parameters determination, as well as the current status of the mission.
