NASA has found a rock on Mars that it has dubbed Skull Hill. The rock is known as a "float rock," and NASA has no idea where it came from.

Such rocks are common on both Earth and Mars and often contain elements like iron and magnesium, which could explain the dark color of Skull Hill. Alternatively, it could be an igneous rock eroded ...

On Earth and Mars, iron and magnesium are some of the main contributors to igneous rocks, which form from the cooling of magma or lava. These rocks can include dark-colored minerals such as ...

On both Earth and Mars, iron- and magnesium-rich igneous rocks often contain dark minerals such as olivine, pyroxene, or biotite. Perseverance is equipped with instruments capable of analyzing the ...

Alternatively, these dark rocks could have a volcanic origin. On both Earth and Mars, minerals like olivine, pyroxene and biotite are known to give igneous rocks their dark color. If these rocks ...
