The Thirty-Meter Telescope (TMT)

The world’s largest optical telescope got the go ahead last Friday when the Hawaiian Board of Land and Natural Resources (BLNR) granted a building and operating permit for the Thirty Meter Telescope (TMT) to be sited on a plateau of Mauna Kea on the island of Hawaii. The next-generation telescope, which uses a 30-meter (98 ft) segmented mirror promises to capture images from the near-ultraviolet to the mid-infrared wavelengths with unprecedented clarity. The green light on construction follows extensive hearings to determine the impact of the new observatory on the area near the volcano’s summit and how the TMT Observatory Corporation would address these issues. The permit process has been held up for two years by a series of objections to building the TMT based on environmental impact, aesthetics and possible interference with native Hawaiian cultural practices, but final approval came at a hearing on April 12 in Hilo, Hawaii, where the TMT was granted a Conservation District Use Permit. Despite Friday’s ruling, TMT still has hurdles to overcome, such as gaining final approval of construction plans by Hawaii's Department of Land and Natural Resources (DLNR) and negotiating a sublease with the University of Hawaii. If these go according to schedule, TMT Corporation hopes to begin construction in April 2014 and the telescope to be operational by the end of the decade. The TMT is backed by the University of California, California Institute of Technology, and the Association of Canadian Universities for Research in Astronomy with the National Astronomical Observatory of Japan acting as a Collaborating Institution since 2008
