When analyzing the lunar surface, orbiters were able to spot deep pits. These could be “skylights” with lava caves underneath. They could provide access to previously untouched lunar material and possibly even water ice deposits.

In addition, ESA can imagine that such caves will become habitats when the moon is colonized. The caves offer natural protection from radiation, micrometeorites and extreme temperatures.
The spherical robot has a diameter of 46 centimeters and is equipped with a LIDAR system with which 3D maps of the caves are created. It also has a stereoscopic camera, temperature sensors, a radiation dosimeter and extendable arms that can be used to remove obstacles.
