These cavities can shield from cosmic radiations, according to the team, who found the celestial bodies held lava tubes up to 1,000 times larger than those on Earth. 'We can find lava tubes on planet Earth, but also on the subsurface of the Moon and Mars according to the high-resolution pictures of lava tubes' skylights taken by interplanetary probes,' said Sauro. 'Evidence of lava tubes was often inferred by observing linear cavities and sinuous collapse chains where the galleries cracked.' 'They are specifically looking for systems that would land on the lunar surface to operate missions exploring lunar tubes', De Waele explained. These programmes include lava tubes on the island of Lanzarote and 36 astronauts from five space agencies have received training in cave hiking.
