ADVANCED PAYLOAD TECHNOLOGY 5 years of data equivalent to DUAL TELESCOPE CONCEPT IN A SINGLE INTEGRATED INSTRUMENT COMPRISING 10 mirrors 1 astrometry function 1 photometry function 1 spectrometry function 3D IMAGES OF A BILLION STARS THE LARGEST INSTRUMENT EVER BUILT USING CERAMICS Structure made of silicon carbide, Gaia will log their position and calculate their speed. A first opportunity to study asteroids in the regions closest to the Sun, normally invisible to telescopes on Earth. a material in which Airbus Defence and Space possesses unique expertise. OPTIMISED FOR STABILITY, DURABILITY AND LOW MASS THERMAL INSULATION A UNIQUE SPACECRAFT HEIGHT Each star will be detected and measured 70 times during the mission. Gaia will determine their position, velocity, distance from Earth, colour and luminosity. 1million the content of CDs or 1000 million million octets. DETECTION AND STUDY OF 200,000 NEW ASTEROIDS 3m 10 m resistant to temperatures BETWEEN -170°C +70°C DIAMETER with sunshield deployed. THREE-DIMENSIONAL MAP OF OUR GALAXY, THE MILKY WAY An astronomical census that will provide answers to questions about the formation and evolution of our galaxy. MEASURING INSTRUMENTS OF UNPRECEDENTED PRECISION Photometer with a resolution of 1billion DISCOVERY OF 20,000 NEW PLANETS Their detection will enable us to improve our knowledge of the mechanisms at work in planetary systems. E=mc² PIXELS (array of 106 CCD detectors each delivering 9 million pixels). EXTREMELY HIGH POINTING ACCURACY Capable of detecting stars with a luminosity stability 400,000 MAXIMUM Cold-gas micro-propulsion system for fine attitude control. TIMES lower than those visible to the naked eye. www.airbusdefenceandspace.com NEW TESTS OF THE THEORY OF RELATIVITY
