OST

The most important source of space law is the 1967 Treaty on Principles Governing the Activities of States in the Exploration and Use of Outer Space, including the Moon and Other Celestial Bodies (OST).¹⁶ […] The OST is a product of the Cold War era when the United States and the Soviet Union—the only states with spacefaring capability—were bitter rivals, each fundamentally distrustful of the other.
