The idea of **Space Archives** is to preserve humanity's most valuable scientific and cultural knowledge in ways that are resilient to disasters on Earth and scalable across planetary distances. A promising approach involves using decentralized technologies like the **InterPlanetary File System (IPFS)** to store and distribute this knowledge.
By leveraging IPFS, archives can be replicated across a distributed network of nodes—including satellites and off-Earth storage systems—ensuring data integrity, resistance to censorship, and long-term access even if parts of the network go offline.
# IPFS in Space
IPFS is a peer-to-peer protocol designed to make the web more distributed. Each file is content-addressed using a cryptographic hash, which makes it ideal for archival use—once stored, data cannot be altered undetectably.
Projects like **IPFS-tiny** aim to bring lightweight implementations of IPFS into low-resource environments like satellites. This opens the door to **off-planet archives** that can sync with terrestrial nodes.
# Archival Use Cases
- **Scientific Datasets**: Space missions, astronomy surveys, and climate data can be mirrored to IPFS and pinned by institutions around the world—and potentially in orbit.
- **Cultural Memory**: Language corpora, public domain books, sound archives, and art collections can be encoded and stored redundantly across Earth and space nodes.
- **Disaster Resilience**: By maintaining redundant archives in space, humanity’s collective memory becomes less vulnerable to local catastrophes or geopolitical instability.
# Current Projects
- Anna's Archive uses IPFS to distribute millions of books and papers across a global node network
- **Starling Lab** archives sensitive records (e.g. human rights evidence) using IPFS and Filecoin to guarantee long-term authenticity
- **Prelinger Archives**, in partnership with Filecoin Foundation, is digitizing historical films onto decentralized networks
- **Libre Space Foundation** is exploring IPFS-tiny for integration into small-scale CubeSats
# Towards Interplanetary Preservation
As we extend our reach beyond Earth, having robust, self-verifiable storage protocols will be essential. IPFS provides a foundation for **interplanetary digital preservation**, where Mars colonies, orbiting labs, and Earth nodes can share a trustless, content-addressable archive.
The future of archives may not just be global—but **solar-system-wide**.
