Would the organic materials survive reentry? Or rather entry?

And what Organic materials did they find?

you’d have to read the article, but it’s ‘infall’ from ‘dust or carbon-rich meteorites’.

Then there’s an immediate question, if S-asteriods (stony asteriods) are more apt to have ‘infall’ (or ‘preserved’ infall) from meteorites, why?

Below is the Nature.com ‘scientific report’ that talks about D-poor water and D-rich water and all sorts of stuff I have no clue about.

Here’s what it says about the organic carbons:

“The organic matter is presented as both nanocrystalline graphite and disordered polyaromatic carbon with high D/H and 15N/14N ratios (δD = + 4868 ± 2288‰; δ15N = + 344 ± 20‰) signifying an explicit extra-terrestrial origin. The contrasting organic feature (graphitic and disordered) substantiates the rubble-pile asteroid model of Itokawa, and offers support for material mixing in the asteroid belt that occurred in scales from small dust infall to catastrophic impacts of large asteroidal parent bodies.”
