We have another new video, this time going through all the main structures of the settlement as it is once it has its full population of 25 000 people. In the timeline, this happens when the Residency Program is complete - the last point where all the permanent residents are trained astronauts. After this, private citizens begin to arrive, and the construction of Lalande City begins. It’s a very extensive and ambitious settlement. You can see it here.

A new 36 minute video has been posted here on YouTube, and is also now at the top of the video list at the bottom of the website’s main page. In it I talk about the equatorial moon colony’s radiation barriers, light funnels, heat radiators, moon stairs, and various other things. The colony was rendered with realistic lighting to really get across the tremendous impact of having a glazed roof that also protects against radiation. The 3d model now has a digital sky containing a sun that lights it very much like the sun actually would. It also has an Earth in the sky that does the same. This video is the first one to really make some important points clearly about why the colony is the way it is, and what it would really be like to be there.

Much work has been done in the last 2 months or so on revamping the structures of Cernan’s Promise. Much more than is shown below, actually. As is common, much of my time is spent staring at my monitor, trying to figure out what makes sense on the Moon. This is punctuated by research online, consultations, and occasional deletion of current work to start over. Maybe a third of my time is actually spent building digital models.
To give a sense of the new directions, here are a few images of the Atrium habitat, the first to be occupied at the Lalande Crater colony of Cernan’s Promise, which is the second colony constructed, after Inukshuk at the north pole. This is an evolution of the previous version. I rebuilt the entire thing fresh. Even with all the thinking, it still went ten times faster than the last build. May this be a sign of things to come, for it is necessary to move beyond this phase soon, and seek to make this a business. It will all be open-source, and the colonies will always be free. But, to do this will take a considerable amount of labor. It needs revenue.

Our new timeline maps out a vast set of complex, interconnecting plans leading to a solar system with major colonies on four worlds. When the timeline ends, there are thousands of ships trading megatons of goods from Mercury to Titan. It costs about as much to go to the Moon as it costs to fly half-way around the world today. Cities are being built at a high clip across the face of the Moon by robot crews that are only lightly overseen by a small number of people. We’ve launched small probes to other stars. There are satellites around every significant celestial body in the solar system, and rovers on all such bodies with a solid surface. Political and economic power has shifted dramatically into space. Our sense of who we are has changed forever.

True space settlement depends on being able to have children out there, including pregnancy, childbirth, and the whole process of raising a happy, healthy child. We know very, very little about what it takes to do this in the harsh environment of space. What we do know suggests that the radiation protection and gravity required is far higher than for an adult. As a mental exercise, let us tackle a chunk of this question. Here follows a sketch of the mother ship - a ship compliant with conservative estimates of the protection needed to safely transport an expectant mother from the Moon to Earth.

The Starship Congress last week was full of expansive ideas of brave new worlds and the odysseys to reach them. I have a new theory that if you pack enough space geeks close enough together they will start to spontaneously levitate. I’m in the thick of this community, but i...

Six weeks ago i posted about a new draft of the solar thermal power plant designed for Cernan’s Promise. Oh how it has changed since then. The process of improving that model has been an important test case of how to elicit input on a design, and work through improving...

There is a strong tinge of escapism among space fans. That isn’t necessarily a bad thing, escapism gets a bad wrap. It just has to be used with care. I think it’s good for people to remember that things could be way, way better than they are. A vision of...

We were chatting over the last week about the thermal energy storage system we have drafted right now for the colony, which is a bit like some solar thermal power plants here on Earth. (I always sort of enjoy it when i have a legitimate reason to specify that i’m...

I couldn’t get along without windows. I don’t care how big the cave is, how realistic display screens are at projecting pleasant outdoor scenes (holographic? well, that would help, but still), or how much time i spend outside (and i don’t think it would be more than 10 or 15...

The timeline for the virtual colonies, it turns out, is not the digestible list of bullet points i thought it would be when i started on it a couple of weeks ago. It is 130,000 words, and i stopped myself before it sucked me in completely. It maps out how...

Kapitalist asked if Moonwards could also work on a plan that could happen in the world we know in a comment on the previous post. That was like pressing a big red button in the middle of my forehead, so i am responding here. If we only think about what...

Sketching things rapidly is really helpful for discussion. In the last 3 weeks i’ve sketched all the main installations of the colony in order to create an overview, and a framework that can be the basis for improvement. There are still a number of undocumented things, nonetheless there is so...

I have spent a lot of time in and around Lalande Crater on the various maps of the Moon. I have my favorite spots. I’ve developed an inordinate fondness for it as clearly one of the handsomest craters. I have burning questions about what is really there. So, when i...

Giant rockets and giant rocket explosions have been all the buzz for the last few weeks. It has gotten me thinking how little conversation there really is about the future being pursued here. There is lots of analysis of the market and the technology, but not of where we are...

Long, long ago, all of the very first nations on the face of the Earth made really big things. They made the very biggest things they could figure out how to. For a long time they raised huge stones over tombs or temples. Then they took to building a...

Moonwards is a bit of a different approach to promoting space. It seems time to properly summarize that. I’m on The Space Show next Sunday, Sept. 11th, and i need to organize my thoughts. It hasn’t seemed useful (up to now) to contrast it with various other projects out there,...

There is no way around it. The different resources of the Moon are in different places, and they don’t seem to be close together. Mapping of resources is really patchy, low-resolution, and incomplete, so maybe there is a sweet spot that helps with this we have only to discover. Probably...

It is time to speak of radiation on the Moon. First i am going to explain it a bit, and point out things a lot of people don’t know. One, we can only make decent guesses how much radiation there is on the Moon. Two, we don’t know what it...

Before i do anything else i am going to deliberately refer you away from this blog, to the wonderful Lunar Swimming entry on Randall Munroe’s What If blog, and please note that i asked that question. Please return for further discussion of the proposition. All done? Okay, hopefully you...

I’ve been mulling how to address effective exercise on the Moon to address a host of health problems that come with low gravity. The main issues are loss of muscle and bone mass, and problems associated with redistribution of fluids, in particular how this can degrade eyesight. Also with...

This may not shock anybody, but building an entire virtual Moon colony is a really big job with many challenges. Trying to become more methodical and organized about it has led to a lull in visible output right now. It has also made the stack of tasks on my desktop...

(Originally posted on site forum Mar 19th, 2016.) by Sigvart Brendberg: The location of the Cernan’s Promise lunar base has several important benefits, however, access to lunar volatiles is unfortunately not one of them.

(Originally posted on site forum April 22nd, 2016.) by Sigvart Brendberg: A nuclear shuttle for transportation of ice from the pole to an equatorial base is limited by the thrust of its engine. That mass must accommodate the mass of the engine and all the other dry mass, and...

(Originally posted on site forum Dec 13th, 2015.) Let’s say you have enough infrastructure on the Moon to fabricate really good mirrors, small motors, and pivoting joints in bulk. And you make 10 km2 of mirrors and set them up outside so you can very accurately point them. That’s 12...

(Originally posted on site forum, Nov 6th, 2015) Here’s a deceptively simple model of Fresnel lenses focusing bands of sunlight on regolith fines that have been delivered and smoothed level by the crane. It’s deceptive for several reasons. For instance, for me, it didn’t feel simple deciding if the crane...

(Originally posted on site forum Oct 9th, 2015) The thing about building a dome out of a spiraling trough of fabric filled with tamped regolith is that the width of each level has to change, as does the radius of the open span. The Tube Filler i posted before might...

(Originally posted on site forum Feb 13th, 2016.) First, i want to emphasize that how much radiation one would actually get on the surface of the Moon is UNKNOWN. I’ve scrounged for figures repeatedly on this, and went with numbers for initial designs that numbers from new sources make sound...
