One Standard Lunar Homestead Atmosphere
Jan 5 2023
One Standard Lunar Homestead Atmosphere
Hi and welcome to Settle the Solar System, a Lunar Homestead podcast.This episode goes over the One Standard Lunar Homestead Atmosphere and how I got to it. The most critical feature of a Lunar Homestead (and any Homestead) pressure hull is that it safely and effectively contains the atmosphere of the habitat. Pretty obvious, right? So, let’s determine exactly what atmospheric pressure and composition our Homesteaders need.Segments[00:00] - Intro[01:10] - One Standard Atmosphere[04:29] - 100% oxygen atmosphere[08:42] - Other buffer gases[12:22] - Skylab atmosphere[14:08] - Newsletter reminder[14:47] - Fire risk[14:47] - One Standard Lunar Homestead Atmosphere[17:39] - Needed research[20:50] - Listener Question - When will the average person live on the Moon?[24:22] - OutroKey pointsA 100% oxygen atmosphere isn't going to work.Homesteaders will need a breathing gas that is mostly nitrogen, just like on Earth.The One Standard Lunar Homestead Atmosphere is 78% nitrogen/21% oxygen at 70.11 kPa.The only way we're going to see Lunar settlement in our lifetime is if we create the Frontier-Enabling Technology and Techniques needed to make it a reality. You can help Lunar Homestead do this.Calls to ActionLeave a review on this platform and on Podchaser, a podcast review site.Subscribe to the Lunar Homestead FREE weekly email newsletter and stay up-to-date on new podcasts, other content, and LH research.Financially support ongoing research and content creation.

SPORE for the rest of the Solar system
Hi and welcome to Settle the Solar System, a Lunar Homestead podcast.This episode covers how we can use Lunar Homestead's Shielded Pressurized Resource Extraction (SPORE) concept to settle the Solar system. From Mercury to the Oort Cloud and everywhere in between.Segments[00:00] - Intro[01:01] - SPORE recap[02:32] - Distance is irrelevant[03:15] - Back to the Moon[05:42] - Mercury[07:23] - Venus[08:42] - Back to Mars[09:10] - Asteroid belt[11:52] - Jupiter[14:50] - Saturn[13:48] - Newsletter reminder[16:32] - Uranus[18:48] - Neptune[20:40] - Kuiper Belt[21:17] - Oort Cloud[22:00] - Orbital settlements[25:03] - Needed research[26:44] - Listener Question - Why are spaceships impractical for a Solar civilization?[32:31] - OutroKey pointsSPORE can be used anywhere we can dig underground.A location with metal-oxides is preferable so Homesteaders can use the oxygen to pressurize the SPORE work area and use the metal to create the habitat pressure hulls.SPORE can be modified to work with a variety of metal oxides.While some locations will be more difficult than others, humanity can make a home anywhere in the Solar system.Orbital settlements will be the pinnacle of space settlement tech. With them we can fill up the Solar system with life.Spaceships, while cool, are not needed for a Solar civilization. All we need are orbital settlements and a little patience.

SPORE - Habitat Creation
Hi and welcome to Settle the Solar System, a Lunar Homestead podcast.This episode covers the Habitat Creation component of the Lunar Homestead Shielded Pressurized Oxygen Resource Extraction (SPORE) concept. Being able to create habitable space while extracting resources and staying safe is a game-changing idea. At least I think it is.Segments[00:00] - Intro[01:09] - Habitat creation[03:26] - Pre-assembled habitats[05:24] - Inflatable habitats[07:02] - 3D printed habitats[08:41] - Sintered regolith habitats[09:52] - Lunar lava tubes[11:34] - Newsletter reminder[12:16] - SPORE hull design[14:14] - SPORE hull material[15:54] - Sealing the hull[16:50] - Airlocks[20:27] - Research needed[22:25] - Subscriber Question - Why are paywalls bad for science?[27:23] - OutroKey pointsSPORE allows Homesteaders to create habitable space while mining the resources needed to manufacture the pressure hull of that habitable space.The current selection of habitat options are inadequate for real Lunar settlement.Lunar iron could be the key to Lunar settlement. It will be a new Iron Age!Paywalls hiding scientific research are bad for science. And everything else.

SPORE - Resource Extraction
Hi and welcome to Settle the Solar System, a Lunar Homestead podcast.This episode covers the Resource Extraction component of the Lunar Homestead Shielded Pressurized Oxygen Resource Extraction, or SPORE, concept. All Lunar settlements will have to engage in mining because that's where the resources are. Using SPORE to mine will eliminate almost all of the hazards and challenges associated with surfacing mining and give us unique options for solving the rest. I'll also answer the question "What is Open Science?".Segments[00:00] - Intro[01:06] - Resource Extraction[02:11] - Regolith properties[04:45] - Mega-regolith properties[06:46] - Problems with Lunar mining[9:39] - Newsletter reminder[10:20] - SPORE solution[12:15] - Lunar gravity[13:28] - Manual hand tools[15:44] - Pneumatic and power tools[18:10] - Potential disadvantages[19:51] - Needed research[23:11] - Listener Question - What is Open Science?[28:32] - OutroKey pointsMost of the Lunar resources are bound up in rocks. Homesteaders are going to have to be miners to get them.While the current paradigm focuses on the regolith; the mega-regolith is a better place for resource extraction.The current paradigm focuses on surfacing mining, an activity that comes with a lot of challenges.SPORE focuses on mining the mega-regolith, avoiding the problematic regolith above.Human miners are a better option than robots. We can use humans now instead of waiting more decades for Lunar mining robots.Humans using Lunar-made hand tools might be a viable option for Lunar settlement creation.There is a lot of stuff that needs to be researched and you can help!Calls to ActionLeave a review on this platform and on Podchaser, a podcast review site.Subscribe to the Lunar Homestead FREE weekly email newsletter and stay up-to-date on new podcasts, other content, and LH research.Financially support ongoing research and content creation.

Selenology 101
Hi and welcome to Settle the Solar System, a Lunar Homestead podcast.This episode covers some basic Lunar geology, which is called selenology, after the Greek goddess of the Moon, Selune. I’m calling it Selenology 101 and it will cover the origin of Luna, its internal structure, and some of the basic features. This way you’ll have some foundational knowledge for future episodes that will go into much more detail.Segments[00:00] - Intro[01:06] - Lunar Origin[04:45] - Lunar Internal Structure[08:19] - Nearside and Farside[10:31] - Newsletter reminder[11:15] - Mare and Terrae[15:41] - Regolith and Mega-regolith[20:13] - Listener Question - What is the Moon illusion?[23:23] - OutroKey pointsWe're pretty sure, but not certain, that Luna was formed from material ejected from a collision between Earth and a Mars-sized planet.The Earth and Luna form a double-planet system.Luna has a small iron core, a dense mantle, and a less dense crust.Luna has a Nearside and a Farside but no "dark side".Lunar geology can be roughly divided into Highlands and Mare.The Highlands and Mare are physically and chemically very different.The top 2 layers of the crust are the regolith and the mega-regolith.The regolith is bad and the mega-regolith is good.The Moon illusion is simply a trick of the brain that we don't yet understand.Calls to ActionLeave a review on this platform and on Podchaser, a podcast review site.Subscribe to the Lunar Homestead FREE weekly email newsletter and stay up-to-date on new podcasts, other content, and LH research.Financially support ongoing research and content creation.
