🚀 The Inner Sphere: A Unique 3D Printable Martian Habitat 🪐

As NASA sets its sights on exploring new frontiers, including the possibility of human colonization on Mars, the development of sustainable and efficient habitats becomes paramount. Northwestern's Martian habitat, known as the Inner Sphere, is a testament to innovative engineering and forward-thinking design. By leveraging the advancements in space material and constructability, this unique habitat offers a superior internal environment, stable and protected against the harsh Martian environment.

Internal Structure: Printing over an Inflatable Pressure Vessel

One of the key aspects that sets the Inner Sphere apart is its internal structure. To achieve this, the habitat is built by printing over an inflatable pressure vessel, which serves as the foundation for the entire structure. This inflatable vessel, an essential part of the Cargo brought to Mars, allows the 3D printer to create a suspended geometry without compromising the structural integrity during the build process. Moreover, the pressure vessel later serves as the primary barrier for maintaining an internal atmosphere, adding an extra layer of protection.

Entryway System: Connecting Astronauts, Rovers, and Equipment

Efficient movement and connectivity are crucial in any habitat design. The Inner Sphere tackles this challenge through its innovative entryway system. The primary entrances and connections for astronauts, rovers, and equipment are located at opposite ends of the structure. By laying out these connections on the main axis, the Inner Sphere allows for future junctions with other Pod units, enabling modularity and expansion.

Cross Beams: The Structural Backbone of the Dome

The stability of any habitat is dependent on its structural backbone, and the Inner Sphere's cross beams fulfill this critical role. These beams, specifically optimized for reduced gravity loading and Mars-level wind loads, provide the necessary strength and safety. Printed in tandem with the pressure vessel, these continuous cross beams ensure the dome's Shape and structural integrity, even under harsh Martian conditions.

Interior Layout: Separating Wet and Dry Areas

Efficient space utilization and resource management are at the core of the Inner Sphere's interior layout. The design strategy revolves around separating wet areas from dry areas, optimizing functionality and reducing the overall material usage. Wet rooms, such as the lab and kitchen, are strategically placed on the opposite side of the habitat from the dry rooms, such as the bedrooms. This concentrated placement of plumbing and mechanical units within the wet side decreases resource requirements and eliminates excess materials running through the structure.

Privacy and Functionality: Designing for Astronauts' Needs

Living in close quarters for extended periods necessitates privacy for astronauts. The Inner Sphere takes this into account by creating a central wall that acts as a hallway barrier, separating the bedrooms from the rest of the space. This central wall also functions as a retractable divider, allowing for a quieter entryway towards the bedrooms or adjusting the flow of movement between adjacent attached units. The sizing and arrangement of different areas are informed by the NASA high seas Mars habitat, ensuring optimal use of space within the compact spherical shape.

Community Building: Connecting Multiple Units

The potential for creating a vibrant community of habitats on Mars is a future aspiration. The Inner Sphere design is conducive to this vision as it offers the ability to combine multiple units into a larger community. With hatch openings directly across from each other, easy connection at either end is possible. The addition of a central node building can further expand the habitat community, creating a network that spans the Martian landscape.

Conclusion

The Inner Sphere, Northwestern's 3D printable Martian habitat, underscores the possibilities of combining effective structural engineering, the utilization of Martian materials, and an intuitive floor plan that prioritizes privacy and functionality. The integration of mechanical systems, printer construction, and the ability to connect habitats opens new avenues for future Martian expeditions. This design showcases NASA's dedication to exploring the Universe, searching for life, and inspiring the next generation of explorers.
