Outer Space Pollution and Environmental Sustainability: A Constitutional and Human Rights Approach

Abstract

Environmental sustainability has long been recognised as a constitutional and human rights imperative, but the discourse has largely remained confined to terrestrial ecosystems. With the rapid expansion of space exploration and commercial satellite activity, the issue of Outer space pollution caused by debris, defunct satellites, and unregulated exploitation has emerged as a critical environmental challenge of the 21st century. This paper explores the constitutional and human rights dimensions of outer space sustainability, with a focus on the Indian context. The Indian Constitution, through Articles 21, 48A, and 51A(g), establishes a robust framework for environmental protection, which can be interpreted expansively to include the cosmic environment. The right to life under Article 21, as judicially expanded by the Supreme Court, encompasses the right to a clean and healthy environment, thereby extending its relevance to space-based ecosystems that directly influence human survival on Earth through climate monitoring, disaster management, and communication systems. Additionally, the Directive Principles and Fundamental Duties enshrine a collective responsibility for safeguarding the environment, including new frontiers such as outer space. From a human rights perspective, outer space pollution undermines the rights to development, security, and intergenerational equity. Future generations are entitled to access and benefit from a sustainable space environment, echoing the principles of the “common heritage of mankind” under international law. India, as a signatory to the Outer Space Treaty (1967) and an emerging leader in space exploration, carries both a constitutional mandate and a moral obligation to advocate for global frameworks ensuring space sustainability. The paper concludes that addressing outer space pollution is no longer merely a technological challenge but a constitutional imperative and a human rights obligation. Integrating sustainability into space law and policy will ensure that humanity’s pursuit of outer space remains equitable, safe, and just for present and future generations. This paper aims to explore the intersection of outer space environmental protection, constitutional governance, and human rights. It emphasizes that the future of humanity and technological progress relies not only on exploring beyond Earth but also on preserving the cosmic environment for present and future generations.
