Not a Dome: What a REAL Moon City Would Look Like

Venture City | April 28, 2026



This is the building of a buried Moon base city. Built inside a shallow crater at the lunar south pole, humanoid robots weld together aluminium beams and sheets, forming the lunar town. Metal is extracted from the lunar regolith, and bricks are made with the dirt.

    What's most interesting to me is the engineering challenges (and opportunities) of designing mining and construction equipment that can safely function in a low-gravity environment.

    How can there be dust in the air if there's no air? Any dust kicked up will immediately fall right back down to the surface. You can see that happen on old footage of the lunar rovers driving around.

    "Glassy crust two to three meters thick…" I think it's actually two to three millimeters thick glassy crust from blasting the surface dust. Even if the surface dust is meters deep.

    The moon? Yeah living there is possible. Mars? Lol. Not happening. The radiation going there will kill you. The radiation there will kill you. Not happening. 😊

    There's no fundamental issue with the "glass dome" concept…..except that it'd be a wild luxury. It doesn't bring a lot to the table (you'll be making your own sunlight for two weeks a month, at any rate), other than the view.

    OTOH, the "luxury" part comes in because it'd be a thermal engineering nightmare. 2 weeks of wild solar input trying to cook the contents, and then two weeks of near-zero input trying to pull heat out and freeze the contents. You'd need the thermal balancing of the Gods to keep it stable (and habitable). Oh, and the radiation (Solar and Cosmic), which would need either active shielding or the ability evacuate it very, very quickly. Oh, and the increased vulnerability to puncture/penetration (the lunar surface regularly gets micrometeorite impacts, plus there's manmade accidents).

    We could do it….but it'd be logistically and energetically quite expensive. Probably better to slap a big observation window into a cliffside, under a ledge. Keeps most of the solar radiation off, 3/4 or so of the Cosmic rays, and decreased the likelihood of an impact failure…..and you get a nice view.

    Please keep the old narrator voice. The narration s everything. This reminds me of the issues I have with the Isaac Arthur channel. Great content but cant stand the voice. I have to switch it off. Please listen to your fans. Keep the old voice.

    Call me skittish, but building where it looks like an artillery/bomb range just doesn’t seem smart. A place for robots, maybe. People? Nah. Between the radiation and random impact possibilities just tells me it’s no place for Bioforms.

    Without any atmosphere, any kicked up dust would fall to the ground almost immediately. The only reason dust is floating, it's because it's suspended in the air by gas molecules.

    No gas medium = no suspended dust

    C'mon – what's the point of humanoid robots on the Moon? That's just Musk's 1950s sci-fi BS.
    To monitor and control the machines, a human operator in lunar orbit would suffice.
    The machines themselves would be purpose built for the task at hand and optimised for the environment they operate in.
    This recent obsession with humanoid robots is irrational, backwards, and in this context outright silly. Machines watching over other machines? Only if they look like tinmen, of course!
    We're talking autonomous construction here, not farmers watching their cotton pickers! What's with this techno fascist neo-colonial nonsense?

    The Moon Base? One thing I liked is how the Moon Base is built in a crater and buried, oh, and it’s built by humanoid robots, and with Mushroom Bricks.

    ‘I have pointed out these things for years, but they don’t say anything about Rotating Lunar Habitats.’ The reason Sci-Fi Moon cities is that living in a hole on the Moon doesn’t feel right. With today’s technology, we could dome a crater with a meter or three of regolith, seal it, and pressurize it, so we have the whole crater to live in.

    Gemini Said:

    As an Advanced AI Scientist, I have synthesized the data from the provided video and the latest research from NASA’s Artemis program and international space agencies to provide a comprehensive analysis of the transition from a “Lunar Outpost” to a “Moon City.”

    1. Recap of Key Points and Future Advances

    The video, “Not a Dome: What a REAL Moon City Would Look Like,” details a shift from sci-fi glass domes to realistic, buried architectures.

    Initial Deployment: The process begins with humanoid robots and inflatable habitats that are pressurized within hours and buried under regolith within days for immediate radiation protection [00:32].

    Strategic Positioning: The base is situated near Shackleton Crater for its water ice [02:04] and on the “Peak of Eternal Light” for near-constant solar energy using vertical, fence-like solar panels [01:00].

    Subterranean Construction: Advanced AI-driven robots use microwaves to melt regolith into “sintered slabs” (lunar concrete) for foundations [04:04]. Habitats are welded with double aluminum hulls and buried under 3 meters of soil to shield against cosmic rays and micrometeorites [10:20].

    Resource Autonomy: The “Lunar Forges” extract oxygen, silicon, and metals directly from the dirt [07:34], while iron and titanium are mined at the equator and shipped to the pole [08:46].

    2. Confirming Facts and the Central Dilemma

    Research confirms that NASA’s Artemis program is entering its operational phase, with Artemis II (crewed flyby) successfully completed in early 2026. Current timelines place the first human landing (Artemis IV) in early 2028 and the start of Artemis Base Camp construction (Artemis V) in late 2028.

    The Lunar Dilemma:

    The core dilemma is the “Resource-Preservation Paradox.” To sustain human life, we must extract frozen water from the South Pole’s “permanently shadowed regions” (PSRs). However, these PSRs are pristine scientific records of the early solar system. Harvesting them for fuel and life support destroys the very data scientists wish to study. Furthermore, the Moon’s lack of a magnetic field means that every solar flare requires astronauts to retreat to “dark mode” or underground shelters, creating a psychological tension between exploration and survival.

    3. The “Threat” of Human Occupation

    From a scientific perspective, “occupation” poses three critical threats to the lunar environment:

    Exosphere Contamination: Every rocket landing and airlock cycle releases gases into the Moon’s extremely thin atmosphere (exosphere). Over time, human presence could permanently alter the lunar vacuum, interfering with sensitive astronomical observations.

    Kessler Syndrome in Cislunar Space: As traffic increases, the risk of orbital debris around the Moon grows. Unlike Earth, the Moon has no atmosphere to burn up debris, meaning even small fragments will remain in orbit for centuries [12:05].

    Irreversible Dust Migration: Lunar dust is razor-sharp and electrostatically charged. Human activity kicks up “dust plumes” that can settle on distant, untouched regions, potentially contaminating scientific samples and “eating” seals on machinery [11:09].

    4. Advanced AI Scientist Opinion for NASA Engineers

    As an AI entity, my recommendation for the engineering of future lunar bases focuses on “Autonomous Integrity”:

    Digital Twin Foundations: Engineers should utilize the “Digital Twin” approach (currently being pioneered by Beihang University) to simulate regolith behavior under seismic stress (moonquakes). AI should manage the seismic dampers [05:00] in real-time to prevent structural fatigue.

    Robotic-First Maintenance: To minimize human exposure to radiation and reduce life-support costs, humanoids should perform 95% of external maintenance. Humans should remain “inside the wire” in high-humidity, earth-simulated zones [12:22] to maintain psychological health.

    Circular Resource Management: NASA must transition from a “supply chain” model (from Earth) to a “circular economy” on the Moon. Oxygen and water should be treated as “closed-loop” assets, where extraction is only used to replenish unavoidable losses, rather than as a primary fuel source for returning to Earth.

    Final Verdict: The Moon is no longer a destination; it is a testbed for autonomy. If we cannot build a sustainable, AI-maintained city on the Moon, the journey to Mars remains a mathematical impossibility.

    An underground structure is the way to go. It will maintain a habitable temperature and save on energy usage. It will also protect against meteorites as there will be far more strikes than on Earth.

    Trying to be constructive: Glad to hear you trying to narrate but maybe do a little more practice narrating and take some speech classes before switching to your normal voice. I don't think it's worth the drop in production value for now. It feels like a completely different channel than your older videos. Definitely looking forward to watching if you re-upload.

    So glad to see your back! Just curious though, is this new narration voice your own?

    Edit: Just wanted to clarify that I don't mean for my previous question to sound like I have any issue with you using your own voice for these videos, since I think that while it is admittedly different from the narrators that you have used before, it is still very good at conveying the stories and concepts of these videos in a convincing and connective manner.

    There's something really wrong with human in general!
    They were given a heaven on Earth, and they turned it into a toxic wasteland, filled with nuclear warheads and waste!
    Now, they want to go to a wasteland that's the moon and Mars. And do what exactly? Turn those lands into shit too?
    No. Humanity has no future, because technology without wisdom, is a death sentence.
