Much remains to be known about the chemical composition of small asteroids. Their potential to harbor valuable metals, materials from the early solar system, and the possibility of obtaining a geochemical record of their parent bodies makes them promising candidates for future use of space resources.

A team led by the Institute of Space Sciences (ICE-CSIC) has analyzed samples of C-type asteroids, carbon-rich minor bodies of the solar system, progenitors of the carbonaceous chondrites.

Their findings, published in the Monthly Notices of the Royal Astronomical Society, support the idea that these asteroids can serve as crucial material sources and identify their parent bodies, as well as for planning future missions and developing new technologies for resource exploitation.

In a natural way, carbonaceous chondrites fall from the sky, although with a proportion of 5% regarding the rest of meteorite falls. However, many of them are so fragile that they fragment and are never recovered. Therefore, they are usually rare and are mainly located in desert regions, such as the Sahara or Antarctica.
