They should attempt to transform a cave into a liveable habitat like spraying some sort of sealant on the walls and install an airlock analog on the cave entrance to prepare us to do it on the moon or on Mars.

@Stu Bur Yup. I could even see a 4 step process: Step 1: Send a smallish rocket-powered drone into a Lava Tube being steered by an astronaut on the rim of the lava tube to map out and scan the lava tube to gether its dimensions. Step 2: Land a lander from orbit down inside the hole of the Lava tube with everything they will need to make the Lava tube airtight. Step 3: Replicate the cave on Earth and train a team of astronauts how to seal the cave properly while wearing space suits. Step 4: Have a rocket land right on the edge of the lava tube with a descending platform so that astronauts can go down into the lava tube and work for the day and ride an elevator back up out of the lava tube so they can directly go back into the safety of the Starship lunar lander... rinse and repeat until they are done.

@Jared Maddox Oh hey there. You just gave me a great idea... sort of haha. What if instead of having an astronaut in the surface of the moon pilot a drone that would float in the "air" by using micro-jet-thrusters placed on the bottom and sides (which would arguably be pretty bad ass) we could just land a "smallish" unmanned craft down into the opening 🕳 from orbit and have it land softly on the floor of the lava-tube and then have it do a quick look about and then have it aim down the tube and shoot multiple projectiles about the size of a basketball with scanning sensors on them and then have them relay the info back to the lander and then up out off the lava tube where it's signal would be picked up by an orbiting satellite and relayed back to Earth. By doing it that way then we would have one less manned trip to the moon. Thanks for getting my brain to rehash my first initial idea. Bravo 👏 👏 👏

I would like to see construction rovers developed and sent to the moon and then Mars. These could first demonstrate proof of concept by digging trenches, setting up power stations, recharging themselves via a base, processing materials into useful products such as tiles, building landing pads, placing rocket sections and inflatable habitats into trenches, connecting sections, adding doors, and covering the habitats and garages with materials for protection. They could start as robotic colonies with practice habitats, perhaps even growing some plants and fungi. Then they can eventually lead to full preparatory teams to build starter bases for humans to visit and live inside.

A cavern is great for using the natural ground above as shielding against micrometeors. A surface building would require serious maintenance if struck.

@JosephHarner Жыл бұрын
I think the threat of micrometeorite strikes is overstated in terms of the moon or mars. The moon's surface was formed over many millions of years. Even less so on Mars, where the tenious atmosphere sets a lower limit on impactor size, and thus frequency. Regardless, on both the primary surface that makes caves desirable is the threat of radiation. However if landing spacecraft near to an existing surface outpost, caves offer great protection against debris kicked up during landing by the rocket exhaust.

Polyurathanes are not chemically stable over long time periods that is a big downside for the wonder material that it is. But many other polymers exist that are practically stable for ever, polyethylenes and similars as someone else mentioned in the comment (a bag/film of pe). With enough energy at hand there is always the option to use lasers to melt and sinter the walls and even insitu creating silicon/iron/aluminium with methods already discussed by Fraser a few months ago because there is no oxygen that would oxidize the formed metals. Many many options. Sign me up, I would gladly help build systems but also do the grunt and long tedious work when I have a good chance of getting home to my family in one piece.

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!

good interview. I can see why the work on surface habitats is seeing a lot of work. I think lava tubes and assume large places but all of the caves I have visited (some in Alberta and some on Vancouver Island) have had very few large caverns... and the way to get to those caverns has not been spacesuit (EVA suit?) friendly. One would not want to land too close to such a shelter either as the vibrations or shock waves could easily cause cave-ins. Hmm, I had thought in the past that caves would be a good place to live on moons or other planets but I think now that it would be harder to build a habitat in a cave than on the surface even assuming the surface habitat was covered in surface material with some hardener.

Are these caves and lava tubes being considered for exploration or habitats? By the lack of exits and safety, caves have to rendered safe and code compliant. Have you seen how tunneling is done and mining shafts are built on Earth? On Mars, the geology has to be evaluated thoroughly before even considering such structures. How stable are the lava tubes? They need to be.lined with airtight form fitting cladding to be pressurized. There's needs to be testing here on earth for converting these caves into habitats

Unlike mines, caves tend to be relatively stable over long periods of time because they have already had thousands to millions of years of seismic events and temperature fluctuations to fall to a stable layout. I think that space habitats will eventually use both caves and mines as habitats and we will have to learn how to use both of them as safely as feasible. Mines will be more flexible in site locations and can enable extraction of resources but require a lot of reinforcements such as bolts. We don’t know enough about the geology of the moon or Mars yet to determine the safety standards required. How many bolts into the walls, how long are the bolts going to need to be, how far apart, and what materials to use for the bolts are just a few of the many questions to answer. Thus I think it will be more feasible to start with existing caves as they are going to be more stable as is and require less reinforcement. As humans live in them, that stability could be degraded but that will be part of their ongoing science and engineering tasks. To fully develop colonies on other worlds, we will have to master mining, manufacturing, and construction in these environments.

Their underground homes should be available when they land. Food and water should all be there. .. This is how you apply the engineering method to the problem. Engineers are better than scientists.

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. discovery com/space/meet-ingenuity-nasa-s-first-mars-helicopter 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.

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.

Masonry, simple cut stones anchored with steel rods or fitted stones. Meanwhile everyone is envisioning using 3d printing when binders, conditions and predictable mineral mixes are difficult to achieve.

Why AREN'T remote-controlled drones used more in Earth caves? Seems much easier and safer.

Try flying a drone through your own home and see how it goes. Then do it again and fly no higher than 3 feet. You may want to try this experiment without pets and spouses present. Some caves have quite delicate formations that you don't want to damage. Maybe try your test flights during the season of extreme decoration (aka Christmas). FYI radio waves that we use to control drones don't penetrate well through rock so exploration would be pretty much limited to line of sight. - so sayeth this caver and rf engineer. Cheers! Addendum: If you could develop a drone that could fly through a crawl space, right itself if it hit something and landed upside down, and could send back pictures with pan/tilt/zoom then I am pretty sure you would have a product that a lot of termite inspectors would really want to have.

Cos radio doesn't work reliably out of line of sight. I've seen what needs to be done with cave exploration robot competitions. It's hard, the robots must either work autonomously or trail wire.

@@richardfellows5041 Actually drones with self righting capabilities and cameras exist. It is the radio frequency communications that are an issue which is why fibre optics are used for pipeline internal inspection with tracked inspection vehicles (think toy tank with a camera and a 100m power cord).

Why are the lava tubes empty and not filled with solidified lava that is now rock?

The molten lava in a lava tube can drain away after its source has stopped, leaving an empty lava tube.

Going into a deep mine shaft can be helpful. The difference between a mine shaft and a lava tube Is GRAVITY ! A lava tube may be safer ! Mars lava tubes will not be easier than the moon because Mars has gravity ! DML

For emergency Mars lave tube exit, Musk will likely have a prop vehicle or jet assisted, I thought I saw a Royal Marines used a jet suit they call a gravity suit to go from a moving rigid hull inflatable to a surface ship, Mars astronauts could get by with a lighter jet suit.
