Treaty obligationsThe international rules pointing to prohibitions on debris creation lie in a limited number of international agreements, most notably is the 1967 Outer Space Treaty. In addition, the Outer Space Treaty points to additional principled obligations against the creation of space debris. Meanwhile, ngoing efforts to achieve international consensus on the prevention of space debris, most evident in the proposals of the Space Debris Mitigation Guidelines, have been worthy endeavors but practically ineffective. In addition, there are efforts underway aimed at actively removing space debris from orbit. Marc G.
