The design of the protective shell can take various forms and be declined in various scales and functionalities, each designed to meet specific needs.

The Extravehicular Activity (EVA) suit is considered a true mini-space station, as it integrates all the essential systems to sustain life, even if only for limited periods. Transport vehicles, such as rovers used for terrain exploration, provide additional protection, particularly against micro-debris, which can be lethal.

Larger spacecrafts not only ensure survival but, thanks to Space Design, offer an increasingly comfortable level of habitability.

The “urban” scale, represented by extraterrestrial habitats, such as lunar or Martian bases, designed to continuously support human life.

Materials and technologies play a crucial role in the design of extraterrestrial habitats, which must be entirely self-sufficient living systems, without any need for terrestrial supplies. It is therefore essential to develop lightweight construction systems, such as inflatable habitable structures, minimize the number of required components, and, where possible, produce a significant portion of the elements on-site using indigenous materials.
