The telescope structure system provides structural support and precise motion, and also space for accessing and servicing the telescope optics, their associated systems (M1S, M2S, M3S), the science instruments, adaptive optics systems, and auxiliary systems. STR cradles the TMT’s 492 articulated mirror segments as they relay the light of astronomical bodies to the M2 and M3 mirrors and finally to the several science instruments located on both lateral Nasmyth platforms
