Researchers call for strengthening sustainability regulations in laws governing space exploration

In the paper titled "Sustainability as a core principle of space and planetary exploration" published in the journal Space Policy, the researchers present a new review of existing planetary protection laws and literature on planetary protection policy and identify key shortcomings of rules guiding human space exploration. Specifically, they cite several questions that existing laws leave unaddressed -- including issues of atmospheric and abiotic contamination -- which constitute important gaps in planetary policy that must be confronted, collaboratively.

Additionally, the researchers present arguments for the necessity of sustainability on planetary objects such as the Moon and Mars and offer examples of terrestrial benefits that could be derived from sustainable exploration practices in space. Specifically, they cite the potential development of new technologies that, while designed for sustainable uses beyond Earth, could advance terrestrial technology.

"Sustainability must become a core principle of human space exploration," said Atri. "Just as we view climate change as the great challenge facing our terrestrial human society, the space community should begin to address space sustainability with the same urgency. The rules and procedures implemented now will govern the next generation of space exploration -- rules that create a basis for clean and safe space exploration that will not only be productive and enforceable for years to come but are also stronger and more specific in their requirements and enforceability.
