Lava tubes can be a solution to a lot of our space problems. They can provide habitat space on Moon, Mars and even beyond. But how do we prepare to explore them? That’s what we’re discussing with Professor Francesco Sauro.

Fraser is discussing with Professor Francesco Sauro how we will explore Otherworldly Caves with Rovers. Francesco is supposed to know a lot about exploring Earth caves, so why did he say we don’t have rovers on Earth???
I commented about a show that was made over 5 years ago about a six-wheeled Limited Intelligence Automated Robot that could decide what terrain is safer to rove over. I’m sure these two know more than I do about caves, but my father was a diver before I was born. I remember him saying when he dove he wasn’t crazy enough to Cave Dive because if anything happened he couldn’t swim to the surface.
I have commented about a Lidar Radar that could be sent underwater to make sub-ocean-floor maps or even fly into caves to map the cave before risking human lives. What I’m getting at is that we as humans have more technology than Professor Sauro and Fraser discuss, and we had it for years… So why are these guys trying to keep it secret?
I’m sure that when Francesco said we don’t have Rovers on Earth like we will be using on the Moon, was because of the low gravity of Mars and the Moon can’t be imitated on Earth, as far as I know… Fraser suggested we use an Ingenuiy type Rover to map the caves with Lidar Radar like has been done on Earth.

I found out about Toroidal Propellers that make less noise and need less power that we could use on Mars, less power means that an Ingenuity has more time to map the caves of Mars. On Earth, they might be miss taken as UFOs at night.??
This Genius Propeller Will Change Transport Forever is brought to us by Ziroth; https://youtu.be/MGy8jvf-DZ0
And in some thousands of years into the future the southern lava tube will declare war against the northern lava tube because of how they have two scopes of algae to desserts instead of only one as all decent people do and large battles will be fought on the surface of Mars we can watch trough our telescopes
Why don't you put professors name in the title? Or at least in the thumbnail? I really like your interviews but i'm not that interested in q&as for example – it would be great to see clearly which video is what type of content. Also I think it would be great for the search algorithm one could find the interviews by names… Thank you for everything you do Fraser!
When we go to other planets, we become cave men again…
Imagine being on Mars, but you have to stay inside a cave most of the time. Most people would not like to be "trapped" inside for so long, think of Covid as a test for example…
And there is no such thing like a one year Mars mission with access to the surface of Mars. It takes 3 years. Or maybe 2 and a half years with much better rockets. Half a Year to Mars, 2 years on Mars, half a year back.
On Mars there is no breathable air, the air is much much thinner than on Earth (only 1% of Earth and without oxygen in the air, even if it was compressed to our air density, there would not be usable oxygen in it).
It is possible, but it requires large amounts of appliances and consumables. And you need people that can endure three years in a rather small housing. You can't just go out and take a walk if you are frustrated.
Why are the lava tubes empty and not filled with solidified lava that is now rock?
its pronounced "LAW-va"………….. not "Laaaaaav-a"
Wow, I didn't realize there was a place on the web for intelligent, but intriguing, talk without any zingers; will come here often.
I've always wondered why Dr Bill Stone has never been interviewed on this channel?
Cool interview. I want to visit a high tech cave city with many connected and colonized tubes before I die. I don't think it's an entirely unreasonable desire.
Hola Frasier! Question: it's said that the moon was created after the collision of Thei with Earth. As both Earth and the new moon were forming, and cooling from this impact, (and must have contained similar materials) would the moon have generated an atmosphere for a period of time?? If so, for potentially how long? Thanks!
My biggest fear is squeezing thru a narrow spot while scuba diving in a deep cave. I enter a vast & wondrous room, promptly exploring it.
When it’s time to leave… I look back to see FOUR openings in the wall from which I came! Which one do I pick, with only a little air left? That’s scary.
What a waste of money
Hey Fraser! Would utilizing human waste as a method to protect astronauts from harmful radiation during an extended space flight be a viable option? It’s my understanding that for the most part astronauts try to dispose of these materials, but if used in this manner I feel like it would be incredibly resourceful. I know how good water is at defeating ionizing radiation, so to me it seems like a no brainer. Thanks, love your work.
Hi Fraser: what is your take on Stephen Hawking's quote from 2017, that the emergence of artificial intelligence could be the "worst event in the history of our civilization". Is it possible that many of us futurists are being too optimistic that AI will a force for overall good, and that we are just fooling ourselves, and Hawking might be correct?
Is there an equivalent to a space toilet (microgravity commode) for multi day cave diving? Surely the diver does not poop in the cave, or do they?
Space Cave Men; the more things change . . .
Not gonna lie 80% here to hear Fraser say lava.
Wow what an interesting perspective! Great guest.
I have to say that I give this interview a super like ❤. It opened my eyes to the chance of undersurface life possibilities 🤔
If earth is little dust in the universe mathematically I don’t exist I guess , brave and hopeful those they work tireless to conquer the next frontier. Aren’t we an amazing nothing. Thank Ing F Cain and the teem ,all the supporters and viewers .
Why lava tubes particularly?
I have spent time exploring lava tubes in my home state. I love the idea, but I also have reservations. I would recommend a specialized drone, rather than having humans go in blind. Navigating a place like a lava tube can be very hard on clothing, let alone a space suit. One sharp rock would ruin your day.
Musk has a number of companies, most of which will be useful for life on Mars. It’s no coincidence. Electric motors, vehicles, batteries, solar power conversion, tunnel boring machinery, robots, and Artificial Ian intelligence, to name a few. Rockets and spacecraft to name the important one. I thinkMusk has a very serious plan to combine his technologies to allow for heavy engineering on Mars. A balance of above ground facilities and u derground habitats/facilities that will allow for human life. Robots may become useful for some surface work, the dangerous, repetitive work. Lava tubes may be useful, however caves are always dangerous due to risk of collapse or rockfall. It takes enormous work to fully line and engineer a rounded rock hole into a safe habitat, conceivably not worth the effort as an option. Probably fun to explore but we don’t know enough yet. The challenges of growing food, making fuel, making industrial bases will be primary for the first few decades on Mars. Hard dangerous work.
it will probably be declared too dangerous, after watching exploring abandoned mines here on youtube even though is crazy dangerous and it was man-made spaces. let alone a lava tube you have to crawl through, and send in the droids.
0:18 no way this is a real picture.right?
