Re: The Moon
This morning, I am thinking about additive and extractive activities on the Moon.
I think that the boring company may do well on most worlds, but perhaps not so much on the Moon as for the relative lack of things like water for it. I will be happy to be wrong about that if eventually method is proven available.
I can think of a number of extractives methods that have recently come into my view;
-Salt Mining with Chlorine and the distillation of the product.
-Laser Sublimation methods.
-I also think that the https://www.quaise.com/ geothermal methods.
I think that some of these could be improved, (Possibly) using chemicals such as Chlorine, in cycles of Oxidation/Chlorination and reduction, (Using Carbon and Hydrogen perhaps).
We will want chemicals on the Moon and at first some of them will be hard to find and process in bulk on the Moon.
While it is a good idea to try to use local resources, I think that also it would be good to figure out how to efficiently and at reasonable cost import ingredients that are easier to provide to the Moon by some effective/efficient methos with utility.
I have previously thought of things like Iron Oxide. But that is not needed for the Moon but is more likely to be taken from the Moon.
In an additive method(s), we may want Urea and Hydrocarbons, to get microbes to make large solids by including regolith and water.
Now I looked at Urea. I would like to crash it into the Moon. The idea of Moon creasing substances of value can be supported by "Space Startup News", as per crashing old space junk on the Moon.
https://www.spacestartupnews.com/
There is a claim from this source, that space junk could be crashed on the Moon using a lower expenditure of delta-v, and the scrap could be of value.
So, I will use that. I will try to produce a practical import method that saves propulsion energy and may provide for needs.
We are familiar with "Airbags". Some people have had trouble grasping the concept of a "Self-Purposed" Airbag in the past.
A "Self-Purposed" "Airbag" would be one that uses its cushioning properties to cushion it's own impact not to protect the impact of another device.
If we have made an Airbag to impact on the Moon at a reasonable speed, we might put Urea grains inside of it. I guess they would be a cargo, and also as likely to bounce around, could "Time Delay" an impact event.
A solid piece of rock can create only a limited, dissipation of impact energy over a limited time interval. Some of it's energy dissipation can dissapated by it's compressive and fracturing nature. If it makes regolith splash, then it provides to energy dissipation time delay by that method.
An Airbag might dissipate energy over an extended time interval, by various methods. But to describe that too much now is to lead attention away from the device I want to propagate in your mind.
I will establish the concept by saying, fill the air bag with Urea foam, and salt that foam with metal Chlorides. Chlorides of metals that are wanted on the Moon but hard to come by.

Urea-formaldehyde foam insulation (UFFI) was widely used in the 1970s for its energy efficiency benefits, but it has since been associated with health concerns due to formaldehyde emissions.
What is UFFI?
Urea-formaldehyde foam insulation (UFFI) is a low-density foam insulation made from a mixture of urea and formaldehyde resin, compressed air, and a foaming agent. It was primarily used in the 1970s to insulate homes, particularly in Canada, where it was injected into wall cavities to fill gaps and improve energy efficiency. UFFI is characterized by its off-white or yellowish color and hardens quickly after application.

Historical Context
UFFI gained popularity during the energy crisis of the 1970s as a cost-effective solution for improving home insulation. However, concerns arose regarding the release of formaldehyde gas during the curing process, leading to health risks. By 1980, the Canadian government banned the use of UFFI in residential construction due to these concerns, although it continued to be present in many homes built or retrofitted during that time.

Health Concerns
The primary health concern associated with UFFI is the gradual release of formaldehyde, a known irritant and potential carcinogen. While emissions decrease over time, certain conditions, such as high humidity or poor ventilation, can lead to increased levels of formaldehyde in the air. Symptoms of exposure may include respiratory issues, eye irritation, and allergic reactions.

Identifying UFFI in Homes
If you suspect that your home may contain UFFI, look for the following signs:
Injection Holes: Homes insulated with UFFI may have visible injection holes on the exterior walls.
Foam Appearance: UFFI can appear as crumbly, tan, or brown foam behind outlet covers or switch plates.
Unusual Odors: A musty or chemical smell in sealed rooms may indicate the presence of UFFI.

What to Do If UFFI is Present
If you suspect UFFI in your home, it is advisable to avoid DIY inspections or removal. Instead, hire a certified professional to conduct an inspection and air quality testing. They can safely assess the situation and recommend appropriate actions if necessary.

Conclusion
While UFFI was once heralded as an innovative insulation solution, its association with health risks has led to its decline in use. Homeowners should be aware of the potential presence of UFFI in older homes and take appropriate measures to ensure safety and air quality.

I believe that this material has much of what is wanted on the Moon, especially if you salted it with metal chlorides.

Most of the atoms in the structure are of significant value on the Moon. The Oxygen is not, but it is needed for the structure of the foam, which is useful to the hoped for impact survival of the devices.
The impact results may be affected by the temperature of the impacting device and the temperature of the surface of the Moon where it impacts.
Also, the nature of the surface that it impacts onto.
For instance, it might hit a trampoline of some kind, or a net. Or a hill of fine dust, that has been provided. You might make a surface softened by feeding gas Oxygen into the pile of dust. A method of fluidization. Or you might fire an explosive device embedded in the pile of dust to fluidize it for a short period of time.
The device might be sent from LEO, with limited navigation and braking abilities. Or it might be dropped from the sides of a ship while the ship lands.
You might be able to shoot some kind of a particle beam at the device from the surface of the Moon to slow it down. Perhaps the output of a Mass Driver, or Magdrive(s), or Neumann Drive(s}.
And then finally you might use it as a landing legs substitute for hardware you wanted to land on the Moon.
What about the Chlorine Salts:
https://en.wikipedia.org/wiki/Chloride
Quote:
Chlorine salts, commonly known as chloride salts, are chemical compounds that contain the chloride ion (Cl⁻) and are formed through the reaction of chlorine with metals or other elements.
What are Chlorine Salts?
Chlorine salts are ionic compounds that consist of positively charged cations and negatively charged chloride anions. The most well-known example of a chlorine salt is sodium chloride (NaCl), commonly known as table salt. Chloride salts are typically soluble in water, although some, like silver chloride (AgCl) and lead(II) chloride (PbCl₂), have limited solubility.

Common Examples of Chlorine Salts
Sodium Chloride (NaCl): The most familiar chloride salt, used extensively in food seasoning and preservation.
Potassium Chloride (KCl): Often used as a salt substitute in food and as a potassium supplement in medicine.
Calcium Chloride (CaCl₂): Used for de-icing roads, as a drying agent, and in food preservation.
Ammonium Chloride (NH₄Cl): Used in fertilizers, as a food additive, and in some medicinal applications.
Properties and Uses
Solubility: Most chloride salts are soluble in water, making them useful in various applications, including food preservation and chemical processes. However, some chlorides, like silver chloride, are only slightly soluble.

Industrial Applications: Chlorine salts are used in a variety of industries, including food processing, pharmaceuticals, and chemical manufacturing.1 Source
Formation of Chlorine Salts
Chlorine salts are typically formed through the reaction of chlorine with metals or through neutralization reactions involving hydrochloric acid. For example, when sodium reacts with chlorine gas, sodium chloride is produced as follows:
2 Na
+
Cl
2
→
2 NaCl
2 Na+Cl
2→2 NaCl
In summary, chlorine salts are vital compounds in both nature and industry, with sodium chloride being the most recognized example. Their properties and solubility make them essential in various applications, from food preservation to chemical manufacturing.

The substances received, might be used to 3D print regolith, or break it down, and get various products.
Microbes can use Urea and Water and some other organics to cement regolith.
Hydrocarbons might be used to grow Mycelium products.
Chlorine extracted can be used in salt mining.
Metals from the Chlorides can be used to makes alloys of Lunar metals.
Substances included might facilitate drilling into the Moon using Lasers and/or other power beams. Maybe "Our gyrotron-powered drilling".
If you add Chlorine, you might get a gas to flow out with Iron in it??? As in Salt mining.
If you add Hydrogen or Carbon/CO, you may get an extraction of Oxygen from the dril location a reduction of the rock.
If you then add these in alternation you may better drill the rock.
But of course, your process has to not eat your drilling equipment.
I think that is quite a lot for one morning.

Is it possible that the root of political science claims is to produce white collar jobs for people who paid for an education and do not want a real job?
