Coherent installs an advanced ultrasonic machine tool to speed hexing of the 1.5 m diameter Thirty Meter Telescope mirror segments.
TMT’s Optics and M1 Segment Support Assemblies (SSA) is ready to enter production following a successful Fabrication Readiness Review that assessed the production of the hardware required to support the primary mirror segments. Larsen and Toubro (L&T), which is supplying the SSAs, is now one step closer to start production and shall proceed with the procurement of raw material.
TMT’s telescope structure subsystem (STR) recently completed two successful Production Readiness Reviews (PRR2 and PRR3) to assess the availability of adequate resources and planning for production, and later for assembly, integration and verification. The STR’s design and future fabrication are activities led by NAOJ and their prime contractor Mitsubishi Electric Corporation (MELCO) in Japan.
A few months ago, TMT Optical engineers traveled to the Netherlands to support the Dutch company TNO install a TMT Segment Support Assembly (SSA) onto an SSA Module Acceptance Test Tool (SMATT). This is an important step in the design and construction of the M1 optics system, a 492-segment primary mirror for the TMT.
The teams working on TMT’s Segment Handling System (SHS) and utility system design received some good news following a series of critical review meetings earlier this spring. The TMT Telescope Structure Subsystem (STR) and Summit Facility (SUM) groups conducted the reviews and based on the outcome, the teams mays now proceed independently with the final design of their systems toward production preparation.
The National Science Foundation (NSF) today issued a Notice of Intent to prepare an Environmental Impact Statement (EIS) and to initiate Section 106 consultation for a potential NSF investment in the construction and operation of the Thirty Meter Telescope.
The successful production of TMT polished glass-ceramic (M1 roundels) is ramping up according to plan.
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.
The handling equipment for TMT primary mirror (M1) segment recently passed its Preliminary Design Review. The custom-designed equipment and tooling will be used to safely handle mirrors within the observatory during operational activities.
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...
