Scientists are abuzz about a coal-colored rock from Mars that landed in the Sahara desert: A yearlong analysis revealed it’s quite different from other Martian meteorites. Not only is it older than most, it also contains more water, tests showed. The baseball-size meteorite, estimated to be 2 billion years old, is strikingly similar to the volcanic rocks examined on the Martian surface by the NASA rovers Spirit and Opportunity, which found water-bearing minerals. Scientists believe an asteroid or some other large object struck Mars, dislodging rocks and sending them into space. Occasionally, some plummet through earth’s atmosphere.
