To Infinity and Beyond (And Beyond): The Legal and Ethical Imperative for Rocket Reusability

Although the Space Shuttle’s first flight was in the 1980s, reusable rocket technology did not achieve mainstream viability until SpaceX’s reusable Falcon 9 rocket revolutionized access to space. This note argues that transitioning to reusable rocket technology is not only a practical and economic advancement, but also a legal and ethical imperative. By analyzing reusable rockets through the “due regard” framework of the Outer Space Treaty, this note demonstrates how reusable rockets mitigate space debris, expand access to space, and can reduce environmental harm. Additionally, reusable rockets address critical ethical concerns by lowering barriers to space exploration, allowing the benefits of space exploration to be shared by more nations, and conserving resources which can be redirected to other pressing needs on Earth. As the global launch cadence continues to rise, widespread adoption of reusable rocket technology is essential to ensuring the long-term sustainability of space exploration while fulfilling international legal obligations and inherent ethical responsibilities.
