Supporting the ELT's main mirror

This giant metal skeleton frame, currently under construction on Cerro Armazones in Chile’s Atacama Desert, will support the primary mirror of ESO’s Extremely Large Telescope (ELT). It will be the largest segmented mirror ever built for a telescope, with a diameter of 39 metres. The mirror will consist of 798 hexagonal mirror segments that work together as one giant mirror. For that, the supporting cell structure has to be sturdy, but light enough to turn around its axis. The mirror cell has openings and walkable areas underneath its mirror supports.
