Michael Bolte, Professor of Astronomy and Astrophysics at the University of California Santa Cruz and member of the Board of Directors for the Thirty-Meter Telescope International Observatory, is speaking about TMT status and progress during the US-ELT presentation/session at AAS 235th meeting in Honolulu.
The leaf springs required for TMT warping harness mechanism, supporting each one of the 492 primary active segments, are being tested and validated in an Environmental Simulation Laboratory.
TMT Project Office representatives visited the India TMT Optics Fabrication Facility, near Bengaluru, India on January 2019. Here is a video of this world class optical facility, whose construction is nearly completed. The next step will be to bring in high-precision machines that will prepare and polish a large number of TMT primary mirror segments.
