On Site Construction Begins On the Thirty Meter Telescope in Hawaii
Press Release
On October 7, 2014, a groundbreaking and blessing ceremony for the next-generation Thirty Meter Telescope (TMT) will launch a multi-national $1.4 billion project near the summit of Mauna Kea, Hawaii.
Although access to the TMT construction site will be limited due to the area’s sensitive environment and harsh physical conditions, the ceremony will be fully accessible via a live-stream webcast.
George Takei, noted actor, director and author, known for his role in the television series Star Trek, will present pre-recorded science segments during the live webcast. Dr. Robert Hurt, researcher, science podcaster and lecturer, will host the webcast, available at tmt.org/buildingTMT.
