Watch rappelling robots dive into a lava tube - for science
Briefly

Researchers tested a novel approach using specialized robots to explore volcanic tunnels, or lava tubes, on the Moon and Mars. A significant test in Lanzarote involved one rover assisting another in rappelling down a shaft into a subterranean cave. Volcanic eruptions create these underground channels, which are found on the Moon and Mars and are considered ideal for human habitats due to their protective qualities. The strategy involved rovers mapping the surface, utilizing a probe to create a 3D map, and planning a descent route for underground exploration.
Researchers conducted tests on Lanzarote, showing how specialized robots can work together to rappel into lava tubes for future explorations on the Moon and Mars.
Satellite surveys of both Mars and the Moon have discovered lava tubes that left by volcanic eruptions, presenting potential safe habitats for human missions.
