What part of a space rock survives all the way to the ground?
When a small asteroid enters Earth’s atmosphere from space, its surface is brutally heated, causing melting and fragmenting. Therefore, why the rocks near the surface survive to the ground as meteorites has been somewhat of a mystery. That mystery is solved in a new study of the fiery entry of asteroid 2008 TC3, published online today in Meteoritics and Planetary Science.
