Future space explorers could go back to being cave dwellers with the discovery of an apparently huge cavernous space beneath the moon’s surface tens of kilometres long. “Intact lunar lava tubes offer a pristine environment to conduct scientific examination of the Moon’s composition and potentially serve as secure shelters for humans and instruments,” the team wrote. You just chip away at the surface,” said Paul Delaney, a professor of physics and astronomy at Toronto’s York University. The moon has no magnetic field, so charged particles from the sun “literally rain down on the surface,” Delaney said. “Humans started out living in caves before we knew how to build comfortable habitats elsewhere on earth,” he said.
