Gaia was a European Space Agency space observatory launched on 19 December 2013 by Arianespace on a Soyuz ST-B/Fregat-MT rocket. It was designed for astrometry, measuring the positions, distances and motions of stars with great precision, as well as the positions of exoplanets through the stars they orbit. Gaia succeeded the Hipparcos mission and is part of ESA's Horizon 2000+ programme. The nominal five year mission was extended, and ESA switched the spacecraft off on 27 March 2025, after which it was put into a heliocentric orbit away from Earth. Processing of its data continues, with the aim of building a three dimensional catalogue of about one billion astronomical objects. Gaia was designed and built by Astrium, now Airbus Defence and Space, with a core team from Astrium France, Germany and the UK.
