going back to the moon lava tube colony thing, the story broke everywhere a few weeks ago that Lunar Recon Orbiter has confirmed several large stable temperature zones in pits on the moon, probably collapsed lava tube sections.

You couldn't ask for a better place to start up a landing port and settlement on the moon. Need a roof and atmosphere. You can make both on the moon, though you'd need some extra compounds to keep the atmosphere from being pure o2, and nitrogen is rare there, I think.

That sounds interesting. We are going back to the Moon so a human base there is a no brainer

definately. I hope that might encourage one of the upcoming robotic landers to choose such a site to land in. there's one in Sea of Tranquility. If any area on the moon has been well mapped out, it's there.

I saw this piece of art at Reddit recently:
https://www.reddit.com/r/Damnthatsi...automatic_transmissions_are_analog_computers/

It reminded me of the clockwork parts of the F-1
https://www.thespacereview.com/article/2410/1
The original F-1 was built somewhat like a wind-up clock: as one part of the startup sequence occurred it would mechanically or in some other way trigger the next part of the startup sequence and so on. Those who have looked at it today marvel at how clever it is.

Yet perhaps "obsolete" tech could re-appear?
https://phys.org/news/2022-09-super-dense-hydrogen-molecules-surface.html
Now a team of scientists from the Max Planck Institute for Intelligent Systems, the Technische Universität Dresden, the Friedrich-Alexander-Universität Erlangen-Nürnberg, and Oak Ridge National Laboratory has demonstrated that hydrogen condenses on a surface at a very low temperature near the H2 boiling point, forming a super-dense monolayer exceeding the density of liquid hydrogen by a factor of almost three, which reduces the volume to only 5 liters per kilogram H2.

So just maybe---LH2 tanks might look like the old automatic transmissions?

3D printing has come a long way---now it can handle stronger metals:
https://techxplore.com/news/2022-09-highest-specific-strength-titanium-alloy.html

"After a simple post-heat treatment on a commercial titanium alloy, adequate elongation and tensile strengths over 1,600 MPa are achieved, the highest specific strength among all 3D printed metal to date."
"For reference, most commercial titanium alloys top out at around 1,000 MPa"

Of more interest to Elon Musk---steel prints
https://techxplore.com/news/2022-09-uncover-3d-print-strongest-stainless-steels.html

Mechanical testing showed that the 3D-printed steel, with its martensite structure and strength-inducing nanoparticles, matched the strength of steel produced through conventional means.

The new study could make a splash beyond 17-4 PH steel as well. Not only could the XRD-based approach be used to optimize other alloys for 3D printing, but the information it reveals could be useful for building and testing computer models meant to predict the quality of printed parts.

"Our 17-4 is reliable and reproduceable, which lowers the barrier for commercial use. If they follow this composition, manufacturers should be able to print out 17-4 structures that are just as good as conventionally manufactured parts," Chen said.

Radiation's effects on metals are also being looked at:

"You can take pure copper, and by processing it so that the grains are nanosized, it can become as strong as some steels," Brad said.

The reduction of vibration is also important:

Professor Junsuk Rho said, "It is significant that the range of metamaterials studied in the nanometer (nm, 1 billionth of a meter) has been expanded to a size that can be used in daily life." He added, "The new system will be applicable to many fields including mechanical structures (e.g., automobiles and aircraft), buildings, and civil engineering in the future."

The concept is good but manufactures only care about the bottom line and this would add to the cost even by a tiny amount they wouldn't adopt this sadly. Might be good for other fields though.

Inside a lab, scientists marvel at a strange state that forms when they cool down atoms to nearly absolute zero. Outside their window, trees gather sunlight and turn them into new leaves. The two seem unrelated—but a new study from the University of Chicago suggests that these processes aren't so different as they might appear on the surface.

The study, published in PRX Energy on April 28, found links at the atomic level between photosynthesis and exciton condensates—a strange state of physics that allows energy to flow frictionlessly through a material. The finding is scientifically intriguing and may suggest new ways to think about designing electronics, the authors said.

Well, apart from the effects of the combustion products of all the chemicals required to get many thousands of tons of matter off the Earth's surface into space. However, if much of the shade could be constructed from materials mined on the Moon or some other body, that would mitigate some of the pollution. Perhaps we need to research how to create bootstrapping robotic construction of large-scale structures from a compact starting seed. It would be a step on the way to creating Von Neumann probes to explore the Galaxy. Then we'd have the problem of handling the immense amount of data returned.
