# Space traffic management is the most urgent governance gap because no authority has binding power to coordinate collision avoidance among thousands of operators

Space traffic management is the most urgent operational governance gap in orbit. The US Department of Defense provides the primary space surveillance catalog, conjunction warnings are issued, but operators independently decide whether and how to maneuver. There is no equivalent of air traffic control for space. No binding international rules determine right-of-way. No legal framework assigns responsibility for collision avoidance. No authority can compel an operator to maneuver.

The US is building TraCSS (Traffic Coordination System for Space) through the Department of Commerce, targeted to become fully operational in 2026, to take over civil space traffic coordination from the military. A coalition of 21 member states submitted a proposal to UNCOPUOS to establish a study group on STM legal aspects. The Cologne Manual provides voluntary guidelines. But no binding international framework exists or is close to agreement.

This matters because space traffic is the first domain where automated collision avoidance systems may need authority to compel action -- raising the question of who is liable when autonomous systems make wrong decisions. The problem will intensify as mega-constellations grow: Starlink alone targets 42,000 satellites, Guowang plans 13,000+, and Project Kuiper 3,236. Managing tens of thousands of active satellites without binding coordination rules is a collision cascade waiting to happen.

## Evidence
- No binding international STM framework exists
- US TraCSS targeted for 2026 operational capability
- 21 member states UNCOPUOS proposal for STM study group
- Starlink 42,000 + Guowang 13,000+ + Kuiper 3,236 = 58,000+ planned satellites

## Challenges
National sovereignty concerns prevent binding international coordination. Operators resist mandatory maneuver rules that could affect mission performance. Liability frameworks for autonomous collision avoidance decisions are legally unprecedented.
