HONOLULU (AP) — A $1.4 billion project to build one of the world's largest telescopes is up against intense protests by Native Hawaiians and others who say building it on the Big Island's Mauna Kea mountain will desecrate sacred land.
Hearings for the project's construction permit are set to begin Thursday and expected to last until next month. It's the second time the project has faced the proceedings.
This time, numerous parties are participating, including a group of Native Hawaiians who support the telescope, and dozens of witnesses are expected to testify. It's not clear when the retired judge overseeing the hearings would issue a ruling.
Here are things to know about the embattled telescope:
THIRTY METER TELESCOPE
A group of universities in California and Canada plan to build the telescope with partners from China, India and Japan. Its primary mirror will measure 30 meters in diameter and be made up of 492 individual segments. Compared with the largest existing visible-light telescope in the world, it will be three times as wide, with nine times more area.
Scientists say the telescope would allow them to see into the earliest years of the universe. The telescope could find planets around other stars in the "habitable zone," where liquid water is possible on a planet's surface, the project's website says. The 13 telescopes already on Mauna Kea have played major roles in discoveries considered among the most significant to astronomy. Partners would receive a share of observing time, along with University of Hawaii scientists.
Telescope officials say Mauna Kea, a dormant volcano, is the best location in the world for astronomy. It's Hawaii's tallest volcano and its summit provides a clear view of the sky for 300 days a year, with little air and light pollution. Opponents say the project will desecrate land held sacred by Native Hawaiians and that there are already too many telescopes on Mauna Kea. All of the highest points in the islands are considered the home of deities, said Kealoha Pisciotta, one of the leaders in the telescope fight.
POWER OF PROTESTERS
Protests disrupted a groundbreaking and Hawaiian blessing ceremony at the site two years ago. After that, the protests intensified. Construction stopped in April 2015 after 31 protesters were arrested for blocking the work. A second attempt to restart construction a few months later ended with more arrests and crews retreating when they encountered large boulders in the road. The telescope has become one of the most divisive issues in the state, with some telescope supporters saying they are afraid to publicly express their stance on the project.
HOW WE GOT HERE
The telescope's board of directors held public meetings before selecting Mauna Kea as the preferred site in 2009. In 2011, opponents requested so-called contested-case hearings before the state land board approved a permit to build on conservation land. The hearings were held, and the permit was upheld. Opponents then sued. In December 2015, the state Supreme Court revoked the permit, ruling the land board's approval process was flawed. That meant the application process needed to be redone, requiring a new hearing.
WHAT'S AT STAKE
If the project dies, not only will that be bad for Hawaii astronomy, but for any high-tech industry considering Hawaii, said Paul Coleman, a Native Hawaiian astrophysicist at the University of Hawaii's Institute for Astronomy. The partners invested $170 million through the end of 2015, Thirty Meter Telescope Executive Director Ed Stone said. The project promises to create 300 construction jobs and employ 140 staff when operational. Earlier this year, telescope officials began looking for alternate sites in case the telescope can't be built in Hawaii.
