| Summary: | Abstract Space infrastructure to protect astronauts and equipment from various hazards is critical for sustainable exploration. However, conventional shelters are challenging to transport due to their large volume, and in-situ construction requires significant time. Deployable shelters can address volume constraints, but thin-panel designs often lack functionality and robustness. This study introduces an origami-inspired shelter made of thick panels that expands into a dome-like shape with a volume several times greater than its stowed configuration. Unlike conventional thick-panel designs, the proposed concept is scalable for various sizes and thicknesses and deployable through simple actuation using gravity and wire tension, without manual assembly. A meter-scale prototype demonstrates stable deployment within tens of seconds. This concept enhances transportability and ease of installation while maintaining protection performance, offering a practical solution for initial manned missions to celestial bodies. |
