A groundbreaking proposal to establish a lunar biorepository aims to preserve the diversity of life on Earth in the permanently shadowed regions of the Moon’s south pole. This innovative concept addresses increasing extinctions on our planet and envisions a facility that requires no power or maintenance to store life forms in cryogenic conditions.
The primary objectives of this biorepository include safeguarding Earth’s biodiversity, protecting species that could benefit space exploration through biomaterials, and preserving microorganisms for potential terraforming efforts on other celestial bodies. The lunar south pole, identified for its deep craters and extremely cold temperatures, presents an ideal site for this initiative, as it would allow for the secure storage of biological samples at below -196°C, the critical threshold for suspending biological processes.
“There is no location on Earth that can provide the necessary cold environment for a passive repository. The moon offers an extraordinary solution,” said a spokesperson for the project, highlighting the focus on maintaining ultra-low temperatures without human intervention.
Samples buried approximately two meters beneath the lunar surface would not only benefit from the natural cold but would also be shielded from harmful radiation.
Current biorepository efforts on Earth, such as the Svalbard Global Seed Vault in Norway, are facing challenges due to climate change risks that threaten their long-term viability. Facilities located near urban populations are also vulnerable to geopolitical instability, making this lunar concept increasingly appealing.
Experts in biological preservation recognize the lunar repository as a viable option. One researcher noted, “Having duplicate facilities on the Moon could enhance the safety of our biological samples significantly.”
However, some experts express concerns about the practicalities of accessing the lunar facility for both adding and retrieving samples. The consensus indicates that maintaining multiple secure options on Earth might provide better redundancy and accessibility. “We would need convincing evidence to ensure the lunar facility could be effectively utilized when needed,” they stated.
Even in scenarios where the lunar repository remains unused, there is value in retaining human artifacts in space for potential discovery by future extraterrestrial civilizations. The initiative aligns with the philosophy of preserving humanity’s legacy for posterity, similar to the golden records attached to the Voyager spacecraft.
