chondrite

So anything you can get from a carbonaceous chondrite asteroid shouldn't be precious to the point of rarity on Venus.

A mission goal was to determine the relationship between C-type asteroids and the carbonaceous chondrite meteorites.

A carbonaceous chondrite asteroid is rich in volatiles to make plastic films as well as metals and stones to coat them with.

The Murchison chondrite is older than Earth and the solar system!

Send a factory factory to a carbonaceous chondrite asteroid 2.

Icy meteorites never survive re-entry that I’m aware of; and most carbon/chondrite ones don’t either, but they are the most common type that do.

Carbonaceous Chondrite asteroids have carbon in the form of coal but also carbonate rocks as well as moderate amounts of water as well as stony minerals (silicon, aluminum) as well as iron.

I made some notes on the issue of how you would build a factory that builds a factory that turns a carbonaceous chondrite asteroid into metallized plastic films.

The best space colony export being considered now is a sunshade installed at Earth-Sun L1 made from asteroid materials, probably some combination of plastic and metal films made from a carbonaceous chondrite.

Well, they appear to have decided it's a carbonaceous chondrite through visual examination alone - you can only really be sure by whacking it through a mass spectrometer and seeing what isotopes you've got.

I want to send something to a carbonaceous chondrite asteroid that can extract the volatiles and turn the coal-like substances and stony substances into large plastic (Kapton!) and metal films.

These are compounds that emerged early from the primeval solar nebula, condensed out and represent the oldest minerals formed in the solar system.[3][4] > Some primitive carbonaceous chondrites, such as the CM chondrite Murchison, contain presolar minerals...

(even if that's the opposite of the joke) Perhaps lithium is easier to find on the lighter "chondrite" (non nickel/iron) type asteroids?

The Chelyablinsk meteor entered at a very shallow angle & was a chondrite with little internal strngth, so it disintegrated over a longer distance forming a “line burst” rather than a single point airburst.

"There is broad consensus that the Chicxulub impactor was a C-type asteroid with a carbonaceous chondrite-like composition, rather than a comet.[29][67] These types of asteroids originally formed in the outer Solar System, beyond the orbit of Jupiter."
