# Spain Offers $1.14 Billion Incentive to Host Thirty Meter Telescope Canary Islands emerge as new candidate after Hawaii construction block. - **Source:** [Slashdot](https://brifing.si/source/0f34d58e-1ccd-45a6-ab82-2de4065dc7ad) - **Published:** 2026-08-04 - **Topic:** [Business](https://brifing.si/c/business) - **Original article:** - **On Brifing:** https://brifing.si/s/567e4cf4-2e91-404a-ae60-dec49b2c104f ## Shift from Hawaii to Canary Islands Spain has proposed a $1.14 billion funding package to relocate the Thirty Meter Telescope (TMT) project from Hawaii, where construction has been blocked for a decade due to local protests, to the Canary Islands. The package covers both construction costs and 50 years of operational expenses, contingent on TMT choosing La Palma. This move aligns with Spain's strategy to become a global hub for astronomical research. ## Three-Pillar Financing Structure The offer includes €400 million ($456M) from Spain's Ministry of Science through CDTI, pledged initially in July 2025. The European Investment Bank may provide €300M ($342M) loan pending due diligence. Spain's official credit institute ICO could contribute another €300M under similar conditions. Additional instruments include guarantees from Spain's export credit agency Cesce and potential EIB financial mechanisms. ## Hawaii's Construction Deadlock Native Hawaiian activists have protested the $1.4B TMT project since 2015 over sacred land claims on Mauna Kea mountain. Legal battles and demonstrations effectively froze the project, prompting partners (US, Canada, Japan, China, India) to seek alternatives. The existing infrastructure at Roque de los Muchachos Observatory in Canary Islands became a prime candidate for relocation. ## New Front in Telescope Race TMT belongs to the same generation as Europe's ELT and the Giant Magellan Telescope. Its 30-meter mirror will study the early universe and analyze exoplanet atmospheres. If Spain's bid succeeds, Canary Islands would host one of the world's three most powerful telescopes, complementing existing astrophysics research facilities. ## Economic and Political Implications Relocation could bring €30M annual tourism revenue and 500 skilled jobs to Canary Islands. However, Spain's CDTI funding model must comply with EU state aid rules. The project could also strengthen Spain's position in EU's Horizon Europe astronomy programs and influence future space telescope projects like Athena planned for the 2040s. ## Technical and Regulatory Process EIB's loan approval awaits a technical feasibility report by late 2024. The project must align with Canary Islands' UNESCO Biosphere Reserve status. Safety measures implemented after Cumbre Vieja volcano's 2021 eruption will impact facility design. Environmental impact assessment is expected by early 2025, with construction potentially starting in 2026 if approved. ## Consortium Dynamics TMT International Observatory includes Caltech, Indian Institute of Astrophysics, and Chinese Academy of Sciences. Spain's offer may influence the consortium's decision to suspend 45%-completed Hawaii investments. If relocated, new contracts would be signed with construction firms, potentially favoring European contractors while maintaining international scientific collaboration. ## Strengthening Europe's Astronomical Leadership Choosing Canary Islands would consolidate Europe's dominance in ground-based astronomy. Synchronized operation between TMT and ELT could accelerate 3D mapping of cosmic nebulae. This investment would also create a testbed for technologies planned for future projects like the Athena space telescope, positioning Spain at the forefront of astrophysical research for decades. ## Sources covering this story - https://science.slashdot.org/story/26/08/04/0040200/spain-offers-114-billion-to-get-thirty-meter-telescope-moved-to-canary-islands?utm_source=rss1.0mainlinkanon&utm_medium=feed — --- _Summary written by Brifing from the original reporting.
