This image shows the Gaia torus, a 3-meter diameter, quasi-octagonal structure, which will support the two Gaia telescopes and the focal plane assembly. It is composed of 17 individual custom-built Silicon Carbide segments which fulfil three basic requirements: light-weight, robust and ultra stable. The arrows show the locations where M1, M'1, M3 and M'3 mirrors will be mounted.
