From left to right: Hu Haixiang, Luo Xiao, Qi Erhui, Hu Haifei Engineers from TMT China Changchun Group, in charge of the fabrication of TMT M3, are testing epoxy bonding pads on a 1/4 M3 prototype in Changchun lab.
Located in the center of the primary mirror, M3 is used to fold and steer the light path coming down from the secondary mirror, so the science beam can be delivered to any of the instruments active on the telescope.

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.
TMT was at "Explore Your Universe" (EYU) event at UCLA on Sunday November 3, 2019. A fun day with an overflow of kids experiencing TMT virtual reality walkthrough and a lively discussion with numbers of interesting questions. The 11th annual EYU event was a huge success, with positive feedbacks and rewarding interaction with the local community.
