Paper: Lava tubes on Earth, Moon and Mars: A review on their size and morphology revealed by comparative planetology

Editor’s note: due to an editorial mixup, two Geobites authors—unbeknownst to each other—wrote about the same paper. We encourage readers to take advantage of this opportunity to learn how two different geoscientists would describe the same exciting development in their field. The other post is here.

When you picture living on another planet, you probably don’t imagine living underground. But lava tubes – underground cave systems formed by flowing lava – are more sheltered from radiation and micrometeorites than the surface of the Moon or Mars. They are also more stable in temperature and could contain water ice. For these reasons both popular culture, such as the National Geographic Mars series, and scientists alike, have hypothesised that humans might live in them one day. Now, a new review and analysis study led by Francesco Sauro at the University of Bologna has sought to investigate potential lava tubes on both the Moon and Mars.

Ever since humankind set foot on the surface of the Moon in 1969, the question of whether one day the human race would inhabit other planets has been pondered over. As a result of the return of samples collected by the Apollo astronauts, and the delivery of meteorites to the Earth, scientists are continuously learning about the geological evolution of other planets.
