Robotic Explorers to Chart Lunar Lava Tubes, Paving the Way for Long-Term Human Presence
As NASA prepares for a sustained return to the Moon with the Artemis missions, a critical challenge has emerged: finding safe and sustainable habitats for astronauts. The lunar surface, while offering scientific opportunities, is exposed to harsh radiation, extreme temperatures, and frequent micrometeoroid impacts. A promising solution lies beneath the surface, within the vast network of lunar lava tubes – and NASA is turning to a trio of specialized robots, SherpaTT, Coyote III, and LUVMI-X, to map and assess these potential underground havens. These robots represent a significant step towards enabling long-duration lunar exploration and, establishing a permanent human presence on the Moon.
These subterranean formations, remnants of ancient volcanic activity, offer a natural shield against the dangers of the lunar environment. The walls of lava tubes could provide protection from radiation exposure, which poses a significant health risk to astronauts, and the constant temperature within the tubes could mitigate the extreme thermal swings experienced on the lunar surface. Micrometeoroids, traveling at speeds up to 70 kilometers per second, likewise pose a threat, but the overhead rock of a lava tube would offer substantial protection. But, before humans can safely inhabit these spaces, a thorough understanding of their structure, stability, and potential hazards is essential. That’s where the robotic team comes in.
Meet the Lunar Explorers: SherpaTT, Coyote III, and LUVMI-X
NASA is employing a collaborative, multi-stage approach to lava tube exploration, relying on the unique capabilities of each robot. SherpaTT, Coyote III, and LUVMI-X are designed to work together, automating much of the exploration process and minimizing the need for direct human intervention. This coordinated effort is crucial for navigating the challenging and potentially hazardous environment within the lunar tubes.
SherpaTT functions as a support robot, specializing in rappelling activities. Its primary role is to enable other robotic missions to reach difficult-to-access vertical areas within the lava tubes. According to a study published in SciRobotics, SherpaTT is equipped with a tether management and docking system (TMDS) that connects it to Coyote III during rappelling operations.

Coyote III is equipped with ground-penetrating radar (GPR) technology, allowing it to explore the subsurface and identify the presence and extent of lava tubes. This capability is vital for mapping the underground network and assessing its geological characteristics. The GPR data will help scientists understand the tube’s structure, identify potential hazards like collapses, and locate areas suitable for future exploration.
LUVMI-X is responsible for mapping and path planning for the other robots, ensuring efficient and safe exploration missions. It will create detailed 3D maps of the lava tube interiors, identifying obstacles and charting the optimal routes for SherpaTT and Coyote III. LUVMI-X also deploys a cube containing sensors that descends into the cave to gather initial data before the other robots enter.
A Multi-Stage Exploration Process
The exploration process begins with LUVMI-X mapping and assessing the conditions around the entrance to the lava tube. Once a suitable entry point is identified, LUVMI-X deploys a sensor-laden cube to explore the initial sections of the cave. Following this initial reconnaissance, Coyote III utilizes its specialized mobility system to navigate further into the tube, creating detailed 3D maps of the interior. SherpaTT provides support during these explorations, particularly in areas requiring rappelling or vertical access. This collaborative approach allows the robots to overcome the challenges of navigating the complex and potentially unstable environment within the lava tubes.
Testing of these technologies has already taken place in a terrestrial analog environment: the lava fields of Lanzarote, Spain. According to NASA, the volcanic landscape of Lanzarote closely resembles the geological features found on the Moon, providing a valuable testing ground for the robotic team.

Why Lava Tubes are Crucial for Lunar Colonization
The potential benefits of utilizing lunar lava tubes as habitats are significant. Beyond shielding from radiation and micrometeoroids, the stable temperatures within the tubes could drastically reduce the energy required for climate control in lunar settlements. This would lower the overall cost and complexity of establishing a long-term human presence on the Moon. NASA is actively considering the construction of habitats within lava tubes as a viable solution for long-duration lunar missions. NASA’s Moon Robots: Exploring Lava Tubes for Future Lunar Habitats
However, before construction can initiate, a comprehensive assessment of the lava tubes’ safety and structural integrity is paramount. The robotic exploration program is designed to gather the necessary data to inform these critical decisions. Understanding the composition of the tube walls, identifying potential weaknesses, and mapping the overall structure are all essential steps in ensuring the long-term habitability of these underground spaces.
Beyond the Moon: Implications for Mars Exploration
The technologies and methodologies developed for lunar lava tube exploration have broader implications for space exploration. The collaborative robotic approach and the use of autonomous systems are directly applicable to the exploration of other planetary bodies, such as Mars. Mars also possesses lava tubes, and the lessons learned from the lunar program could be invaluable in planning future missions to the Red Planet. The ability to explore subsurface environments remotely and autonomously will be crucial for searching for evidence of past or present life and for identifying potential resources for future human settlements.
The development of SherpaTT, Coyote III, and LUVMI-X represents a significant investment in the future of space exploration. These robots are not merely tools for scientific discovery; they are essential components of a larger strategy to establish a sustainable human presence beyond Earth. By overcoming the challenges of exploring and utilizing lunar lava tubes, NASA is paving the way for a new era of space colonization.
