All delivered TMT blanks are stored in India TMT Optics Fabrication Facility (ITOFF) inspection area, at IIA Crest Campus, Bengaluru.
The M3 system includes the M3 Blank, the M3 Mirror (a 3.5m by 2.5m flat elliptical mirror), the upper portion of the tertiary mirror (M3) system Tower, the M3 Cell Assembly, the M3 Positioner Assembly, the interface hardware between the M3 System and the Telescope Assembly, and support for receiving, assembly, inspection and verification of the M3 System onto the TMT Telescope at the Observatory. TMT M3S will approximately weigh 12 tons.

Two TMT Primary Segment Assemblies fitted with aluminum mirror segments have been successfully installed into the Multi-Segment Integration & Test facility at the TMT lab.
Group picture of TMT Science Forum 2019, held on the campus of Xiamen University in China, November 2019.
The science cases and instrument design of one of TMT’s first decade instruments, the High Resolution Optical Spectrograph (HROS) were discussed during a workshop on the day before the Forum in China. This workshop was aimed at facilitating the definition of HROS main science requirements and the building of its core science team.
