NASA's Dawn spacecraft confirmed the link between HED meteorites and Vesta through compositional mapping and crater analysis from 2011 to 2012. The spacecraft documented extensive impact cratering in Vesta's southern hemisphere, including the Rheasilvia basin ,  a 500-kilometer impact structure that excavated material from multiple crustal layers and ejected fragments into space.\u003c\/p\u003e\n\u003cp\u003eHowardites represent the impact gardening process on Vesta's surface. Unlike eucrites (volcanic basalts) or diogenites (plutonic cumulates), howardites formed when later impacts pulverized and mixed already-solidified crustal rocks. This mechanical mixing preserved fragments from different geological settings on Vesta: shallow crustal basalts, deeper plutonic rocks, and occasionally material from Vesta's mantle. The brecciated structure in this specimen records the violence of the impact environment on an airless body where ejecta from one crater can travel across the surface and impact elsewhere, creating a complex regolith of mixed fragments. \u003ca href=\"\/pages\/learn-about-meteorites\"\u003eLearn About Meteorites\u003c\/a\u003e provides additional context on achondrite classification and formation processes.\u003c\/p\u003e\n\u003ch2\u003eFrequently asked questions\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eIs this meteorite authenticated?\u003c\/strong\u003e Yes.

Vesta differentiated early in solar system history, concentrating metal into its core.
