Someone paid $5.3 million for a piece of Mars

Add this to the list of "things that might be fun if you had a buttload of money": Someone forked over $5.3 million in a Sotheby's auction to own a piece of Mars.

To get here, an asteroid first hits the Red Planet to eject material from its surface. (Sotheby's says there are only 19 Martian craters large enough to have spit out this one.) That chunk

A new Martian climate model suggest a mostly cold, harsh environment

The Curiosity rover was sent up the Mount Sharp, the biggest sediments stack on Mars.
