If humans finally colonize the Moon, lunar caves formed from primeval volcanic activity could provide shelter from cosmic radiation and extreme temperatures. Enter a team of scientists from South Korea who have built a simple rover prototype that can traverse rough terrain. “Consequently, the wheel could absorb impacts and navigate uneven terrain while remaining robust under extreme lunar conditions,” the paper reads. “The results highlighted the deployable wheel’s ability to combine adaptability, durability, and operational efficiency, making it a promising solution for diverse and challenging mission scenarios,” the paper reads.
