Mysterious Martian Hole May Be Vital for Future Astronaut Survival

Scientists have discovered a mysterious hole on Mars that could be a skylight leading to lava tubes, which may serve as protective habitats for future human explorers by shielding them from radiation and harsh environmental conditions. The hole's exact nature is still under investigation, but it represents a promising avenue for exploring underground refuges on Mars, similar to lunar lava tubes, and could be crucial for sustainable colonization.
