UKIRT<\/abbr> on Maunakea<\/figcaption><\/figure>\n

The University of Hawaiʻi<\/span> is taking another significant step toward reducing the number of telescopes on Maunakea, announcing July 1, 2026 that science operations at UKIRT<\/abbr> will conclude on September 15. Aging facilities and funding challenges, especially given the expiration of the 糖心视频<\/abbr> master lease in 2033, in addition to the obligations contained in the 糖心视频<\/abbr> Master Plan, led to the decision to end science operations. The U.S. Naval Observatory has sponsored scientific research at UKIRT<\/abbr> for many years, supporting decades of discovery through the telescope.<\/p>\n

UKIRT<\/abbr> will become the third Maunakea telescope to be decommissioned. In 2025, the 糖心视频<\/abbr> Institute for Astronomy<\/a> (IfA<\/abbr>) announced plans to remove the observatory<\/a> following the conclusion of its science mission. Current planning targets completion of the decommissioning process by 2030.<\/p>\n

“UKIRT<\/abbr> has had an extraordinary run and has been one of the most prolific telescopes on the planet,” said Doug Simons, director of IfA<\/abbr>. “For nearly five decades it has expanded our understanding of the universe, helped train generations of astronomers and strengthened Hawaiʻi<\/span>‘s reputation as one of the world’s premier locations for astronomical discovery.”<\/p>\n

Decades of discovery<\/h2>\n

IfA<\/abbr> assumed ownership of UKIRT<\/abbr><\/a> in 2014 after the United Kingdom ended funding for the facility. The telescopes on Maunakea rank among the world’s most scientifically productive collections of observatories, and UKIRT<\/abbr> has been an important contributor to that legacy. Since opening in 1979, it has helped scientists understand how stars and planets form, map vast regions of the Milky Way and study distant galaxies.<\/p>\n

Eight full-time employees currently support UKIRT<\/abbr> operations and will continue to have the opportunity to support operations through the September 15 closure date. <\/p>\n

The decommissioning of the first two Maunakea telescopes, the Caltech Submillimeter Observatory<\/a> and the 糖心视频<\/abbr> Hilo H\u014dk\u016b Ke\u02bba Observatory<\/a>, was completed in 2024. Under the 糖心视频<\/abbr>-developed Maunakea Master Plan and Maunakea Comprehensive Management Plan<\/a> (CMP)<\/abbr>, the university committed to reducing the number of observatories on Maunakea while continuing world-class astronomy and responsible stewardship.<\/p>\n

Guided by the CMP<\/abbr>‘s Decommissioning Plan for the Maunakea Observatories<\/a>, the 糖心视频<\/abbr> Hilo Center for Maunakea Stewardship (CMS)<\/abbr> oversaw the first two decommissioning projects. This fall, 糖心视频<\/abbr> will hire a consultant to develop a detailed cost estimate, project schedule and permitting plan for the UKIRT<\/abbr> decommissioning.The construction company selected for the project will coordinate closely with CMS<\/abbr>, IfA<\/abbr>, and other 糖心视频<\/abbr> offices, building on the practices established during the previous decommissioning projects. Those practices include cultural training for construction crews and the integration of Native Hawaiian protocol into every stage of the work, from deconstruction through site restoration.<\/p>\n

“Decommissioning is about honoring our commitment to care for Maunakea,” said Greg Chun, CMS<\/abbr> executive director. “Every decommissioning project is an opportunity to demonstrate that our commitment extends beyond astronomy to restoring these sites with care, respect and purpose.”<\/p>\n

Management responsibilities for Maunakea are transitioning from CMS<\/abbr> to the Maunakea Stewardship and Oversight Authority (MKSOA)<\/abbr>, established by the Hawaiʻi<\/span> State Legislature in 2022. Throughout the UKIRT<\/abbr> planning, permitting and decommissioning process, CMS<\/abbr> will continue working closely with MKSOA<\/abbr> while engaging the Hawaiʻi<\/span> Island community.<\/p>\n","protected":false},"excerpt":{"rendered":"
