A current, authoritative list of Artemis Accords signatories that includes Portugal and shows a total of 60 signatories.
NASA’s official Artemis Accords page states that on January 11, 2026, Portugal became the 60th nation to sign the accords. A NASA news release dated January 12, 2026, describes Portugal as joining the Artemis Accords alongside 59 other countries, confirming it as the 60th signatory. Therefore, the claim is True because multiple primary NASA sources explicitly identify Portugal as the 60th country to sign the Artemis Accords.
