The Thirty Meter Telescope (TMT) is a 30-meter Adaptive Optics (AO), Segmented Mirror-reflecting Extremely Large Telescope (ELT) plan, intended for Mauna Kea, Hawaii, for first light in 2022. Construction was delayed for some time, with the possibility of relocation to Canary Islands, but as of 2017, plans are proceeding to built it at the Mauna Kea Observatories (MKO).
