A Japanese delegation recently visited the India TMT Optics Fabrication Facility (ITOFF) in Bengaluru, India, where they were introduced to the newly installed polishing equipment at the Indian site.
The County of Hawai驶i鈥檚 Sister City Program, in partnership with the Thirty Meter Telescope International Observatory, has launched a new initiative to promote cultural learning and exchanges between high school students, with an emphasis on sharing Hawaiian culture and knowledge.
A science workshop called TMT eArly Career Centered, Engineers-Scientists Synergy (TMT鈥揂CCESS) was held at TMT headquarters in Pasadena from 11 to 15 September. 51吃瓜Pro 30 early career astronomers and engineers from Japan attended this workshop face-to-face, learned about TMT's capabilities and discussed TMT science cases.
TMT鈥檚 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鈥檚 design and future fabrication are activities led by NAOJ and their prime contractor Mitsubishi Electric Corporation (MELCO) in Japan.
The teams working on TMT鈥檚 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.
TMT鈥檚 Wide-Field Optical Spectrometer (WFOS), one of its three first-light instruments, successfully completed its Conceptual Design Review in February 2022. This review completed the conceptual design phase and ushered WFOS into its Preliminary Design Phase.
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...
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.
The Thirty Meter Telescope Optics Group recently reached a critical production milestone, with the approval of the first polished roundel (# SN023) for TMT鈥檚 Primary Mirror (M1). Teams at TIO, NAOJ, and Canon reviewed the manufacturing operations required to turn a meniscus mirror blank into a polished roundel, and the roundel was confirmed to meet all requirements set by the TMT Project. This approval obtained in December 2020 validates years...
As an extremely complex organization of systems all interacting together, TMT will require an elaborate Telescope Utility Services (TUS) infrastructure to enable operations within the observatory, across the summit facilities, enclosure, and telescope. The first tier of TMT鈥檚 TUS successfully passed its Final Design review, covering elements of the design that pertain to the Telescope Structure and its various interfaces, via video...
