As space grows both more competitive and congested, there is an urgent need for global space governance—treaties, standards, norms, and regulations—to limit the potential for military conflicts and help to preserve and sustain space for future activities. This panel will address the challenges of space governance, identifying both opportunities and barriers for countries to cooperate on space issues. It considers proposals for an international treaty to ban destructive anti-satellite testing, a reinvigorated Outer Space Treaty, a new moon treaty, and the need for new space actors to have a greater role in these policy discussions.
