The telescope's construction was initially approved in 2011, but protesters who were against the project from the get go due to the sacred grounds it's planned to be built on blocked construction attempts numerous times. The project's website was even hacked in 2015. However, the state's supreme court nullified the project's permit in December of 2015 because it had been granted without giving the opposition a chance to officially air their concerns.
The Thirty Meter Telescope stands to give us a deeper view into the universe than we've been able to achieve before. It would be three times wider than the current largest visible-light telescope and have a resolution over ten times better than the Hubble Space Telescope's. Mauna Kea was selected because it offers clear views for the majority of the year with very limited light and air pollution. It's so ideal, there are already 13 telescopes built on it.
The Associated Press reports that the new permit stipulates the project's employees must commit to cultural and natural resources training and adhere to strict environmental regulations. Local residents must also be hired for jobs generated by the project "to the greatest extent possible."
But for many, those requirements aren't enough to justify continued loss of sacred land. Protest leader Kahookahi Kanuha said, "For the Hawaiian people, I have a message: This is our time to rise as a people. This is our time to take back all of the things that we know are ours. All the things that were illegally taken from us."
