Deployable interlocking structures for Martian bases

We propose a new construction system for a Martian base based on the hybrid blocks made of pre-fabricated and delivered shells filled in-situ with regolith. In order to avoid the difficulties with connecting the building blocks (as mortar being cured in low pressure conditions loses its strength), we propose to use the octahedron block geometry, which supports topological interlocking. Structures based on topological interlocking do not require binder to maintain their integrity. Furthermore, they have high fracture resistance and self-healing properties, thus ensuring long term stability of the structure.
