TMT Hawaii

US-ELTP digital background2

In 2009, following an extensive site testing campaign, Maunakea in Hawaii emerged as the preferred site for the Thirty Meter Telescope (TMT). What has followed has been more than 12 years of planning and design, regulatory processes, and community consultation. TMT does not have a timeline to resume on-site construction. The project’s renewed focus is an effort to connect more meaningfully with the Hawaii community.
