The mission of TMT International Observatory LLC (TIO) is to design, build, operate and eventually decommissioning the Thirty Meter Telescope (TMT). When complete, TMT will be one of the most powerful ground-based optical/infrared telescopes in the world, providing the capability to study exciting astronomical problems from the nature of extra-solar planets to the first stars in the universe. TIO consists of the California Institute of Technology, Canada, India, Japan, and the University of California.

The Astro2020 Decadal Survey report ranked the US-ELT Program (US-ELTP including TIO, GMTO, and NOIRLab) the top priority for ground astronomy.  As such, TIO is working with US-ELTP to enable the U.S. National Science Foundation’s investment in both telescopes with broad access for the entire U.S. astronomy community.

The TIO Project Offices are located in Pasadena, CA, and Hilo, HI, USA. The development and delivery of the various telescope subsystems is distributed amongst the TIO partner institutions, collaborators, industry, and the Project Office. TMT is planned to be complete and ready for science operations in the mid 2030s.
