Steve Jurvetson may never walk through the frigid canyons and craters of Mars, but the venture capitalist celebrates his passion for the red planet in a different way: He collects pieces of Mars found on Earth.
At his office in Menlo Park, California, Jurvetson displays a rare treasure: the second-largest Mars rock in private hands. The textured, brownish-red rock, discovered in 1999 in the Dar al Gani desert in Libya, crystalized 180 million years ago. Today, it rests in a glass showcase in the hallway of Jurvetson's firm, Draper Fisher Jurvetson.
"It is quite moving to hold a piece of Mars in your hands," Jurvetson told CNBC, "and to reflect on its incredible interplanetary journey, and the science that gives confidence as to the origin of this unusual rock."
Jurvetson declined to say how much he paid for it, though he noted that it cost "more than my first house."
