Gaia is the European Space Agency satellite which will provide the first 6-Dimensional census of the Milky Way. Gaia will image the sky with its billion-pixel video camera for 5 years, delivering data which will revolutionise our view of the Milky Way, while making substantial advances in mapping our inner Solar system, testing gravity, and providing the first robust distance scale in cosmology.
