2nd Rock May Back Martian Life Theory

A NASA scientist has discovered what may be signs of life in a second meteorite from Mars, CBS News reported. David S. McKay, a researcher at Johnson Space Center in Houston, said he spotted “possible cell structures in at least one other meteorite.” McKay and other scientists first reported in August that tests of tiny golden-colored bits of a meteorite suggest microscopic life on Mars 3.6 billion years ago. The newest sign of life was found in a rock billions of years younger than the first, McKay said, noting that “most of the lifetime of Mars is in this range between the two meteorites.”
