Update on TMT Primary Mirror Production in the Bay Area
June 23rd, 2021 Engineering & Technology

The production of TMT’s primary mirrors in North America is progressing very well. Several polished glass-ceramic roundels are currently in production at the Coherent manufacturing facilities; three were recently finished and shipped to the TMT storage facility in the Bay Area.

TMT Laser Guide Star Facility Passes Design Milestone
June 3rd, 2021 Engineering & Technology

The TMT Laser Guide Star Facility (LGSF) has successfully completed the first phase of its Preliminary Design Review (PDR1). The LGSF will be responsible for generating artificial laser guide stars that will be used with TMT’s Adaptive Optics (AO) systems, including NFIRAOS, the Observatory’s first-light AO facility.

Cooling TMT's Adaptive Optics System
June 2nd, 2021 Associate Project Manager Blog

In a previous set of blog entries, we discussed the principle of adaptive optics, which TMT will use to remove the effects of turbulence in the Earth's atmosphere. TMT's first light adaptive optics includes the Narrow Field Infra-Red Adaptive Optics System (NFIRAOS), which is being designed and built by our Canadian colleagues at the Herzberg Astronomy and Astrophysics Research Centre, in Victoria.

TMT Metrology Equipment Arrives in California
June 1st, 2021 Engineering & Technology

The optical metrology and test set for TMT’s primary mirror segments has arrived at its warehouse in California. It was sent by Arizona Optical Systems (AOS) in Tucson, Arizona, on May 11 and arrived safely the day after at the TMT storage facility after a 500-mile journey. All fabrication and test tooling for the complete metrology system were also included in the freight.

TMT is deeply saddened by the passing of TMT Systems Engineer Hugh Thompson on May 7, 2021. Hugh was a colleague, good friend and inspiration to many of us who were fortunate to interact with him over his career.

TMT’s Telescope Structure progresses to Production Readiness
May 13th, 2021 Engineering & Technology

A virtual meeting was conducted on April 5, 2021 between representatives of the National Astronomical Observatory of Japan (NAOJ, TMT Japanese Partner Institution) and the TMT Project Office (TMTPO) Telescope Structure Subsystem (STR), Systems Engineering (SE) and Project Management (PM) teams. The goal of this closeout meeting was to verify closure of all major actions from the STR Production Readiness Review (PRR) 1 which was conducted...

Progress made on TMT mirror production
April 29th, 2021 Engineering & Technology

TIO recently celebrated the completion of another eight newly polished roundels produced for the TMT primary mirror by Canon in Japan. The TIO and NAOJ teams responsible for the mirror polishing held a face-to-face meeting virtually on April 27, 2021 to confirm that the polishing results met the demanding requirements for these parts.

Update from TMT Science Advisory Committee
April 23rd, 2021 Science & Astronomy

TMT’s Science Advisory Committee (SAC), which has been meeting bi-monthly since the start of the Covid-19 pandemic, recently met to address the project status, its scientific potential and suitable instrumentation. The SAC is composed of representatives from each TMT partner who advise the Project on TMT’s design, strategies and operational matter that can have a significant impact on TMT science.
