In addition to financial support, each country also contributes significant scientific and technical resources. The national research agencies that form the Gemini partnership include: the US National Science Foundation (NSF), the Canadian National Research Council (NRC), the Chilean Agencia Nacional de Investigaci贸n y Desarrollo (ANID), the Brazilian Minist茅rio da Ci锚ncia, Tecnologia e Inova莽茫o, the Argentinean Ministerio de Ciencia, Tecnolog铆a e Innovaci贸n, and the Korea Astronomy and Space Institute (KASI). The observatory is managed by the Association of Universities for Research in Astronomy, Inc. (AURA) under a cooperative agreement with the NSF. The NSF also serves as the executive agency for the international partnership.</p> <a href="/contact"><img alt="U.S. National Science Foundation (NSF) logo" class="text-center" src="https://noirlab.edu/public/media/archives/logos/original_trans/logo028.png" width="100%" /> </a> <ul class="small-block-grid-1"> <li class="text-center "><a href="/contact"><img alt="Canadian National Research Council (NRC) logo" src="/sites/all/themes/gemini/zurb_foundation_gemini/images/logos/participants/NRC.svg" width="60%" /> </a></li> <li class="text-center "><a href="/contact"><img alt=" Chilean Agencia Nacional de Investigaci贸n y Desarrollo (ANID) logo" src="/sites/all/themes/gemini/zurb_foundation_gemini/images/logos/participants/conicyt.svg" width="60%" /> </a></li> <li class="text-center "><a href="https://www.gov.br/lna/pt-br/composicao-1/coast/obs/gemini"><img alt="Brazilian Minist茅rio da Ci锚ncia, Tecnologia e Inova莽茫o logo" src="https://noirlab.edu/public/media/archives/logos/svg/logo029.svg" width="60%" /> </a></li> <li class="text-center "><a href="/contact"><img alt="Argentinean Ministerio de Ciencia, Tecnolog铆a e Innovaci贸n logo" src="/sites/all/themes/gemini/zurb_foundation_gemini/images/logos/participants/mincyt.svg" width="60%" /> </a></li> <li class="text-center "><a href="/contact"><img alt="Korea Astronomy and Space Institute (KASI) logo" src="https://noirlab.edu/public/media/archives/logos/svg/logo021.svg" width="60%" /> </a></li> <li> <hr style="border: 1px solid black;" /></li> <li class="text-center "><a href="/contact"><img alt="Association of Universities for Research in Astronomy, Inc.
