Asteroid Vesta to reshape theories of planet formation

Thu, 07/17/2014 - 03:00
If Vesta has less of an olivine-rich mantle and more of a pyroxene-rich crust, then the proportion of materials making up Vesta, and probably Earth and other telluric planets, is different from what was previously expected.
