First TMT Segment Support Assembly (SSA) successfully completed. This photograph, taken at the L&T assembly lab, shows a complete segment mechanical support system with position actuators and whiffle trees mechanical interfaces.
India-TMT, along with industry partner Larsen and Toubro (L&T) in Coimbatore, have successfully manufactured and assembled the first Segment Support Assembly for TMT production.
TMT volunteers participated in the outreach event, offering activities on exoplanets, telescopic observations and even a virtual reality journey through the planned TMT observatory.
