What treaties do we have that guide the use of Space?

Foundational Framework: The Outer Space Treaty (1967)​

The primary legal framework governing all extraterrestrial activity is the Treaty on Principles Governing the Activities of States in the Exploration and Use of Outer Space, including the Moon and Other Celestial Bodies, commonly known as the Outer Space Treaty.

​Established in 1967, this agreement serves as the "constitution" of space. It dictates that outer space is not subject to national appropriation, meaning no country can claim sovereignty or ownership over Mars, the Moon, or any asteroid. Instead, space is defined as the "province of all mankind," intended for peaceful exploration and scientific investigation for the benefit of all nations, regardless of their economic or scientific development.
