When astronauts land on Mars someday, they might have to live in lava caves or lava tubes to survive the harsh radiation that rains down on the Martian surface every second. But which caves could offer them the best chance of survival? This is what a recent study presented at the 55th Lunar and Planetary Science Conference hopes to address as Dr. Anatoliy P. Vidmachenko from the National University of Life and Environmental Sciences of Ukraine investigated where, how, and why lava tubes and lava caves could aid future Mars astronauts regarding their survival. This study holds the potential to help scientists and engineers help mitigate risks for future Mars astronauts and what steps that need to be taken to make that a reality.

The exploration of Mars continues, with many nations sending robotic missions to search for evidence of past life and learn more about the evolution of the planet’s geology and climate. As of the penning of the article, there are ten missions exploring the Red Planet, a combination of orbiters, landers, rovers, and one helicopter (Ingenuity). Looking to the future, NASA and other space agencies are eyeing concepts that will allow them to explore farther into the Red Planet, including previously inaccessible places. In particular, there is considerable interest in exploring the stable lava tubes that run beneath the Martian surface.
These tubes may be a treasure trove of scientific discoveries, containing water ice, organic molecules, and maybe even life! Even crewed mission proposals recommend establishing habitats within these tubes, where astronauts would be sheltered from radiation, dust storms, and the extreme conditions on the surface. In a recent study from the University Politehnica Bucuresti (UPB), a team of engineers described how an autonomous Martian Inspection Drone (MID) inspired by the Inginuity helicopter could locate, enter, and study these lava tubes in detail.

The surface of Mars is hostile and unforgiving. But put a few meters of regolith between you and the Martian sky, and the place becomes a little more habitable. Cave entrances from collapsed lava tubes could be some of the most interesting places to explore on Mars, since not only would they provide shelter for future human explorers, but they could also be a great place to find biosignatures of microbial life on Mars.
But cave entrances are difficult to spot, especially from orbit, as they blend in with the dusty background. A new machine learning algorithm has been developed to quickly scan images of the Martian surface, searching for potential cave entrances.

Lava tubes and chambers attract a lot of attention as potential sites for bases on the Moon and Mars. They provide protection from radiation, from temperature swings, and even from meteorites. They beg to be explored.

Planetary exploration, specifically within our own Solar System, has provided a lifetime of scientific knowledge about the many worlds beyond Earth. However, this exploration, thus far, has primarily been limited to orbiters and landers/rovers designed for surface exploration of the celestial bodies they visit. But what if we could explore subsurface environments just as easily as we’ve been able to explore the surface, and could some of these subsurface dwellings not only shelter future astronauts, but host life, as well?

Could lava tubes on the Moon and Mars play a role in establishing a human presence on those worlds? Possibly, according to a team of researchers. Their new study shows that lunar and Martian lava tubes might be enormous, and easily large enough to accommodate a base.

When magma comes out of the Earth onto the surface, it flows as lava. Those lava flows are fascinating to watch, and they leave behind some unique landforms and rocks. But a lot of what’s fascinating about these flows can be hidden underground, as lava tubes.
These lava tubes are turning out to be a very desirable target for exploration on other worlds, just as they are here on Earth.
