Thirteen astronomical observatories that call the mountain home have evacuated workers and curtailed their operations. > Work on the TMT was set to resume on July 15 after a four-year delay caused by legal challenges and protests. Hawaii’s state supreme court ruled in October that the TMT’s construction permit was valid.
