Bon Voyage, Euclid! Congrats to our sister company Boostec!

The final mirror shape is accurate to nine millionths of a millimetre under Earth gravity.

All six of Euclid’s ‘ Korsch configuration ’ mirrors, plus the telescope itself – comprisingmore than 30 parts as well as the mirrors – as well as the more than 10 parts making up the mission’s Near Infrared Spectrometer and Photometer and the optical bench that 2/2 surrounds them are all made from the same material: not glass, but Silicon Carbide (SiC), a ceramic only foundnaturally in space.
