Polishing a GMT 8.4-m mirror

One of seven 8.4-m (27.6 ft) segments comprising the Giant Magellan Telescope (GMT) primary mirror is polished at the Steward Observatory Mirror Lab in Tucson, AZ. The GMT is a ground-based extremely large telescope planned for completion in 2018 in Las Campanas Observatory, Chile.
