It is now possible for ground-based optical/infrared astronomers to sweep aside the disturbances of the Earth's atmosphere. Diffraction limited observing and unprecedented light collection with a 30 meter aperture telescope is the promise of the next generation of giant telescopes. The Thirty Meter Telescope (TMT) Project will open this new generation of astronomy. With a filled aperture and finely segmented 30 meter diameter primary mirror, large Nasmyth instrument platforms accommodating a powerful suite of science instruments, and a facility laser guidestar adaptive optics system TMT will provide powerful seeing-limited and diffraction-limited obseving. TMT is completing its design and development, has now prototyped and tested all of its critical components, is developing key elements of the industrial supply chain and is preparing to initiate construction in late 2011 on a 4000 meter Mauna Kea site in Hawaii. An international consortium is forming to realize this powerful new observatory.
