The Billion-Year Backup Drive
Humanity's Time Capsule... On the Moon

If Earth faced a catastrophic event, could our story survive?
That’s the idea behind the Lunar Ark, a proposed vault of human knowledge to be stored in the Moon’s lava tubes. DNA samples, seed banks, music, books—even languages—would be frozen and preserved in deep-space cold.
Why the Moon? It’s geologically stable and outside Earth’s disaster zone. If anything ever happened here, future explorers (or survivors) might find the record of who we were—and maybe rebuild from it.If Earth faced a catastrophic event, could our story survive?
That’s the idea behind the Lunar Ark—a visionary project to store DNA, seeds, books, music, and even languages in the Moon’s lava tubes. But it’s not just symbolic: the plan includes cryogenically preserving 6.7 million biological samples, including sperm, eggs, and spores from Earth’s known species.
The concept was proposed by Dr. Jekan Thanga and his team at the University of Arizona’s SpaceTREx Lab, with contributions from Mary Hagedorn at the Smithsonian. The Moon, with its stable geology and safe distance from Earth’s disasters, could serve as the ultimate long-term backup drive.
If something ever happened to life on Earth, a future civilization—or visiting explorers—might recover this lunar vault and find the raw materials to rebuild biodiversity... or at least understand what was lost.
