Sustainability beyond Earth: Integrating Anthropocene lessons into guiding principles for responsible space expansion

Abstract

The profound impact of human activities on the Earth’s global ecosystem raises questions about our environmental responsibility, and their far-reaching consequences also cast doubt on the perceived progress of humanity in achieving social justice and equality. As we now contemplate the exploitation and settlement across multiple celestial bodies, we find ourselves at a crossroads, facing the possibility of extending these effects beyond the atmosphere and orbital environments. This article proposes a foundational framework for the conscientious exploration and use of outer space against the backdrop of the Anthropocene era. The approach is cautionary, emphasizing the critical lessons learned to avoid repeating the environmental, ethical, and societal challenges that have shaped our time on this planet. It advocates for sustainable and responsible practices as we extend the anthropogenic footprint to extraterrestrial settings.
