The Republic of San Marino became the 76th signatory to the Artemis Accords during a ceremony in Rimini on Friday, Sept. 25, 2026, with NASA and U.S. Department of State officials present, according to NASA. Minister of Industry and Technological Research Rossano Fabbri signed on behalf of San Marino. Gregory Mann, NASA's Europe representative, took part alongside U.S. Consul General in Florence Joseph Tordella.

NASA Deputy Administrator Matt Anderson described San Marino as joining a growing coalition of nations committed to peaceful, transparent and responsible space exploration. Fabbri said San Marino shares the principles and values expressed in the accords and believes signatory states will contribute to international cooperation in space and to peaceful uses of space.

NASA and the State Department established the accords in 2020 with seven other founding nations. The principles commit signatories to explore peaceably and transparently, render aid to those in need, enable access to scientific data, avoid interference with others' activities, and preserve historically significant sites and artifacts through best practices. NASA said signing opens the door to future lunar exploration opportunities with the agency.
