A recent social media post by U.S. President Donald Trump on Truth Social featuring an image of the Moon with the words “The Moon Is Ours” has reignited discussions about who legally controls lunar territory.
Distinction Between Online Post and Formal Claims
No Official Executive Order: Trump did not issue an executive order declaring the Moon U.S. territory.
Satirical Screenshots: A separate viral screenshot claiming the president had officially declared the Moon U.S. territory was identified as satire rather than a genuine post.
Legal Status Under International Space Law
The 1967 Outer Space Treaty: Developed through the United Nations and signed by the U.S., Article II of the treaty explicitly rules out national ownership of celestial bodies through sovereignty, occupation, or any other means.
Exploration vs. Ownership: While countries can own their equipment, spacecraft, and objects sent to space, planting a national flag does not turn the surrounding lunar land into national property. Article I dictates that space exploration and use should benefit all nations.
Future Lunar Exploration and the Artemis Accords
Growing International Framework: As nations prepare for a new era of lunar exploration, NASA’s Artemis program and the Artemis Accords establish guiding principles for activities on the Moon. As of 2026, 71 countries had signed the accords.
Complex Future Challenges: With governments and private companies exploring permanent infrastructure and lunar resources, the limits set by the OuterSpace Treaty ensure that the Moon remains outside the ownership of any single nation.
