[meteorite-list] Chocolate Hills rock on Mars shows a strange coating that one researcher has called a "blueberry sandwich."

Hello Lister,

Any one in the mood for a Blueberry sandwich from Mars? Here is an article someone told me about at work.

Abstract:

NASA's Mars rover Opportunity has found a Martian rock covered in weird material as its odometer hit a major milestone this week, with the long-lived robot completing equivalent to a half–marathon on the Red Planet.

Opportunity, now in its seventh year on Mars, found the odd Mars rock during the past six weeks studying investigating a crater called "Concepción."
