Gaia is now en route to its launch site in
Designed and built by Astrium for the
Gaia will carry ultra-modern instruments, including the most sensitive telescope ever made. Like the space telescope carried by Herschel, as well as all the instruments made by Astrium for Earth observation missions, this cutting edge equipment is the result of unique expertise developed by Astrium in the field of silicon carbide (SiC) telescopes. Astrium and its partner Boostec, the innovative SME, have created a veritable economic sector through their space-industry achievements - a remarkable success story. The SiC produced in the French Midi-Pyrenees region is exported around the world.
Gaia will also use a 'photographic' sensor of unprecedented accuracy. The precision of Gaia measurements will be extremely high: from the Moon, it would be able to measure the thumbnail of a person standing on Earth. It has a huge focal plane made up of 106 CCD detectors gathering 1 billion pixels. For its attitude control, the spacecraft will also utilise cold gas propulsion (nitrogen), which will allow it to continuously adjust pointing performance with the required extreme accuracy.
Gaia will be located at one of the five Lagrangian points in the Sun-Earth system, at the L2 point. Lagrangian points are very precise points in the cosmos where a body such as a satellite remains fixed and perfectly stable in space. Located 1.5 million kilometres from Earth, these locations are vital for astronomy observation missions which require high pointing stability.
