Eying A $1 Trillion Industry, 'Resource-Hungry' China Rapidly Increasing Tech For Asteroid Hunting
https://eurasiantimes.com/china-rapidly … d-hunting/
According to Morgan Stanley, the space industry, which is currently valued at around $400 billion, is projected to reach $1 trillion in value in less than two decades. This has also prompted a competition between great powers such as US and China, who are vying for supremacy in space.
In 2017, Ye Peijian, the Chief Commander and Chief Designer of the Chinese Lunar Exploration Program, revealed details of a plan that could potentially put an unmanned craft on an asteroid and mine the rock for metals like palladium, platinum, and others that are used in items such as smartphones and automobiles.
“Water and platinum group metals that are abundant on asteroids are highly disruptive from a technological and economic standpoint,” Noah Poponak, a Goldman Sachs analyst, noted in an investor note.
Last year, A Chinese space mining start-up, Origin Space, launched a robot prototype, the NEO-01, into low Earth orbit (LEO) to capture and destroy space debris and eventually mine asteroids as well.
For years, Chinese scientists have been proposing plans for asteroid mining.

We were 13 years into the topic before we got back to making use of them.
Of course, size of the rock matters just as much as to its composition of materials for the ability to make use of it as a ship capable of life support. Which is not quite the same as Colonizing / terraforming small asteroids as a ship but it could be if it's very large.
The mining most likely will contain material to create Basalt fiber which brings us to how as well as where SLS and what asteriod will we go to

Unknown class of water-rich asteroids identified

I wish they would describe some of the new class of object better.

At the same time, the infrared spectra support conclusions as to the bodies’ chemical and mineralogical composition. Just like Ceres, there are minerals on the surface of the discovered asteroids that originated from an interaction with liquid water.
The small astronomical bodies are quite porous. High porosity is yet another characteristic shared with the dwarf planet Ceres and an indication that the rock material is still quite original.
“Shortly after the formation of the asteroids, temperatures were not high enough to convert them into a compact rock structure; they maintained the porous and primitive character typical of the outer ice planets located far from the Sun,” explains Dr Wladimir Neumann, a member of Prof. Trieloff’s team. He was responsible for the computer modelling of the thermal development of the small bodies.
So, they might be like porous rock sponges with ices in much of the pore space?
Maybe the Trojans of Jupiter tend to be of this sort.
Done.

First look at Ryugu asteroid sample reveals it is organic-rich
by Bill Steigerwald, NASA's Goddard Space Flight Center
Quote:
Asteroid Ryugu has a rich complement of organic molecules, according to a NASA and international team's initial analysis of a sample from the asteroid's surface delivered to Earth by Japan's Hayabusa2 spacecraft. The discovery adds support to the idea that organic material from space contributed to the inventory of chemical components necessary for life.
Quote:
The science of prebiotic chemistry attempts to discover the compounds and reactions that could have given rise to life, and among the prebiotic organics found in the sample were several kinds of amino acids. Certain amino acids are widely used by terrestrial life as a component to build proteins. Proteins are essential to life as they are used to make enzymes which speed up or regulate chemical reactions and to make structures from microscopic to large such as hair and muscles. The sample from Ryugu also contained many types of organics that form in the presence of liquid water, including aliphatic amines, carboxylic acids, polycyclic aromatic hydrocarbons, and nitrogen-containing heterocyclic compounds.
So, if this is similar to outer belt asteroids, then, a very good inventory of materials. And close enough to the sun that mirrors could be used as a power supply to work with them.
Done.

Well, I found this today: https://www.msn.com/en-us/news/technolo … 88ed&ei=20 Quote:
NASA just found a new type of ancient asteroid loaded with water
Story by Elisha Sauers • 5h ago
1 CommentScientists have identified a new type of large, dark space rock in the main asteroid belt between Mars and Jupiter that is flush with water.
This asteroid group has striking similarities to Ceres, the only dwarf planet within the inner part of the solar system, known for being chock-full of H2O. But these asteroids — though relatively close to Ceres — are orbiting farther out in the belt than their much larger sibling.
The discovery, made with measurements taken at the NASA Infrared Telescope Facility in Hawaii, adds to the mounting evidence indicating asteroids in the main belt migrated there from a cold nether region, perhaps beyond the orbit of Neptune or Pluto. Such clues suggest the massive gravity of giant planets in the primitive solar system changed their travel plans, nudging the asteroids to their present location, relatively closer to the sun.
So, to me it looks like we figure out what we could and should do about the Moon, and then head for Mars/Phobos/Deimos.
Then definitely the asteroid belt is the place to be, all of it even Jupiter's trojans. So, orbital habitats will be a big thing.
From there then in time Venus and Callisto.
Maybe Titan.
Done.

We Could Get Material On The Moon By Shocking It With Lightning
https://www.universetoday.com/162739/we … lightning/
Lately, plenty of ideas have been floating around for methods to mine the Moon. That is undoubtedly partly due to the growing enthusiasm for Artemis, NASA’s lunar exploration program, and its planned support for a long-term human presence on the Moon. But what would make the best technique to get valuable material off the lunar surface? How about zapping it with lightning? That is the idea behind a NASA Institute for Advanced Concepts grant given to Dr. Amelia Grieg of the University of Texas at El Paso. And it seems to work.

Interstellar meteorite found at the bottom on the ocean!

It's composition appears to be very different to any solar system material that we know. It appears to be rich in beryllium, uranium and lanthanides. This may indicate that it formed from a nebula rich in the ejecta from supernova.
