Kitt Peak National Observatory
For astronomers to study the heavens, it takes engineers here on earth to build the structures and design the myriad equipment required to unlock the secrets of the cosmos. The Kitt Peak National Observatory is the world's largest collection of optical telescopes (22 optical and two radio telescopes), including the world's largest solar telescope (McMath-Pierce), and the mammoth Mayall Telescope with its 4-meter mirror. Keeping large telescopes and their heavy mirrors stable as they track objects across the sky requires both sturdy telescope structures and advanced electronic feedback equipment that detects structural deflections.
