The India TMT Optical Fabrication Facility (ITOFF), being constructed at the Indian Institute of Astrophysics campus in Hosakote, near Bengaluru, is rapidly approaching completion. The world-class optical facility was built by India-TMT as part of its contribution to the TMT partnership.
Pasadena, CA – February 6, 2019 – The Indian Institute of Astrophysics (IIA), on behalf of India TMT, recently signed a contract with Larsen & Toubro (L&T) to manufacture 100 Segment Support Assemblies (SSA) for the TMT. L&T is one of the largest leading construction engineering companies in India.
Beijing, China – On 19-21 December 2018, Thirty Meter Telescope China (TMT-China) Team held its science and technology annual assembly and TMT High Resolution Optical Spectrograph Instrument (HROS) Workshop at the headquarters of the National Astronomical Observatories, Chinese Academy of Sciences (NAOC).
The TMT International Observatory Board of Directors recently endorsed the recommendations made by the Science Advisory Committee (SAC), to select a slit-mask-based imaging spectrograph design for WFOS (Wide Field Optical Spectrograph), its second first-light instrument.
Pasadena, 5 October, 2018 - The TMT Observatory Executive Software (ESW) has passed a key milestone and is now ready to enter final design phase. An ESW Preliminary Design Review phase1 (PDR1) was held at the project office on September 27, 2018. ThoughtWorks, ITCC and TMT Engineers presented the overall Executive Software architecture and operations concepts, as well as their updated requirements and technical use cases.
PASADENA (July 26-27, 2018)– The Thirty Meter Telescope Optics Group recently achieved a critical milestone by passing its Primary Mirror Optics System (M1S) final design review. The review board, comprised of international reviewers and observers from various institutions including ESO, ITCC, JPL, JWST/Ball Aerospace, KECK, NAOJ, NIAOT, and the TMTPO*, met at TMT headquarters in Pasadena.
PASADENA July 11, 2018 – The conceptual design of TMT’s Cryogenic Cooling System (CRYO) has passed its conceptual design review. Engineers from the Technical Institute of Physics and Chemistry (TIPC) of the Chinese Academy of Sciences (CAS) joined TIO engineers at the project office to present the system that will be used to maintain parts of TMT’s first-light science instruments at cryogenic temperatures of 77 K.
The TMT International Observatory (TIO) Board of Governors at its meeting this week deferred a decision on whether to continue towards building the Thirty Meter Telescope in Hawaii, or to consider the alternative in the Canary Islands.
Marking a major production milestone, TMT has entered into a contract with Coherent Inc., one of the world’s leading providers of lasers and laser-based technology for scientific, commercial and industrial customers, to polish its U.S. manufactured primary mirrors (M1) segments.
On September 7, 2017, a TMT Primary Segment Assembly (PSA), fitted with an aluminum mirror segment, was successfully installed into the Multi-Segment Integration & Test (MSIT) facility at the TMT lab in Monrovia, California. This is the first time a PSA has been integrated into hardware in a way that accurately reflects how the segments will be installed into the final mirror cell of the Thirty Meter Telescope.
