Weighing 3.3 metric tons, the U.S. National Science Foundation Inouye Solar Telescope's 75mm-thick Zerodur glass mirror is shaped by 142 actuators to counteract gravity’s pull, solar heating, and other distortions. The actuators are part of the Inouye’s advanced optical system to keep our solar view clear!
