A NASA media advisory published Aug. 27, 2026, said Turkey was scheduled to sign the Artemis Accords at a ceremony planned for 2:30 p.m. EDT on Monday, Aug. 31, at NASA Headquarters in Washington, which would make it the 71st country signatory. NASA Administrator Jared Isaacman was to host Turkish Minister of Industry and Technology Mehmet Fatih Kacır, together with U.S. Department of State officials. The advisory described the event as in person only and set an RSVP deadline of 11 a.m. on Aug. 31.

According to the advisory, the United States, led by NASA and the State Department, joined seven other founding nations in 2020 to establish the Artemis Accords, responding to growing governmental and private interest in lunar activities. NASA described the accords as the first set of practical principles aimed at enhancing safety, transparency and coordination of civil space exploration on the Moon, Mars and beyond.
