Once the crew arrives at their destination, the astronauts can simply unfold the structure and just add water to it.
The fungi will be able to grow around that framework into a fully-functional human habitat, while being safely contained within the habitat to avoid contaminating the Martian or lunar environment.
The cyanobacteria layer can produce water and create oxygen for the astronauts by photosynthesising light shining through the icy layers.
NASA revealed even “if some mycelia somehow escaped, they will be genetically altered to be incapable of surviving outside the habitat”.
