Scientists believe that two asteroids might be fragments of long-lost "planetary embryos" from the early solar system.

Angrites are a distinct group of meteorites, characterized by olivine-bearing basaltic minerals and unique isotopic signatures (such as oxygen, magnesium, and chromium isotopes) and elemental ...

They're made up of chondrules, or small, spherical grains of silicate minerals such as olivine and pyroxene. Herd believes the meteorite that struck Velaidum's property came from an asteroid belt ...

NASA’s Perseverance rover is making history by collecting handpicked Martian samples for future return to Earth. Scientists are eager to study these specimens to unlock secrets about Mars’ ancient ...

The Perseverance rover has sampled mm-size lithic fragments containing olivine likely from at least two source regions from ...

The bedrock is abundant with olivine, a mineral also found in Mars meteorites. Olivine can undergo serpentinization — a process that occurs when olivine interacts with water and heat — which on Earth ...

Nakhlites are a unique suite of ~20 Martian meteorites. They are basaltic pyroxenites with mineralogies dominated by cumulative pyroxene and olivine. Traditionally considered to represent a shallow ...
