The GMTO Corporation today announced the start of hard rock excavation for the Giant Magellan Telescope’s massive concrete pier and the foundations for the telescope’s enclosure on its site at Las Campanas Observatory in Chile. Using a combination of hydraulic drilling and hammering, the excavation work is expected to take about five months to complete. Excavation is a key step towards the construction of the GMT, which is expected to see first light as early as 2024.
