Study nixes Mars life in meteorite found in Antarctica
Fox News
A 4 billion-year-old meteorite from Mars that caused a splash here on Earth decades ago contains no evidence of ancient, primitive Martian life after all, scientists reported Thursday.
Tiny samples from the meteorite show the carbon-rich compounds are actually the result of water — most likely salty, or briny, water — flowing over the rock for a prolonged period, Steele said. The findings appear in the journal Science.
During Mars' wet and early past, at least two impacts occurred near the rock, heating the planet's surrounding surface, before a third impact bounced it off the red planet and into space millions of years ago. The 4-pound rock was found in Antarctica in 1984.
