Spain’s Bold Bid for the Thirty Meter Telescope
The international consortium behind the Thirty Meter Telescope (TMT) has acknowledged Spain’s invitation and €400 million pledge to host the megatelescope on La Palma. In a social media statement, the TMT organization called Spain’s support “a positive development reflecting continued international confidence in the project.” While no final decision has been made, the consortium confirmed it is “carefully reviewing the proposal and looks forward to further dialogue with Spanish partners.”
La Palma vs. Hawaii: A High-Stakes Decision
La Palma’s Roque de los Muchachos Observatory remains the backup site to Hawaii’s Mauna Kea, where the TMT faces fierce opposition from Native Hawaiians who consider the mountain sacred. Spain’s renewed push—first announced in 2019 and now reinforced with funding—positions La Palma as a viable alternative. On July 23, Spain’s Ministry of Science, Innovation, and Universities framed the investment as a strategic win for the EU, Spain, and the Canary Islands, particularly La Palma.
Political Momentum and Budget Cuts Shift the Balance
La Palma’s chances improved after U.S. federal budget cuts weakened Hawaii’s position. During a meeting of the Canary Islands Astrophysics Institute (IAC) on the island, Science Minister Diana Morant unveiled Spain’s formal proposal. The TMT consortium emphasized its commitment to selecting the most suitable location, pledging a “thorough and prompt” evaluation of Spain’s offer.
