On 4 December, The LST prototype, under construction at Roque de los Muchachos Observatory in La Palma, reached an important milestone when its 18-ton mirror dish, mostly made of reinforced carbon fiber tubes, was lifted to the lower structure successfully. After careful preparation, the dish was lifted 18 meters above the ground and secured using a 200-ton crane. The whole operation only took four hours. A big congratulations to the team for bringing the telescope one step closer to operation!
