Lunar pits and lava tubes offer exceptional potential for future human habitation and contain critical records of the Solar System’s history. However, their steep entrances and extreme environmental conditions have so far deterred successful exploration. While current proposals often rely on risky tethering systems to lower rovers, we introduce a robust, soft-deployable wheel designed for safe "direct drop" deployment.

This innovative approach bypasses the vulnerabilities of traditional deployable mechanical systems, which are prone to failure from cold welding, abrasive lunar dust, and thermal expansion. By utilizing a soft-robotics strategy, we minimize mechanical complexity while ensuring high durability. Our design demonstrates how a flexible, adaptable structure can maintain integrity under space conditions, proving that soft robotics is a practical and reliable solution for accessing the most challenging frontiers of space exploration.
