The Question of Microfossils in Martian Meteorites

During the last week in April, a major conference on astrobiology was held near NASA’s Johnson Space Science Center in League City, Texas. (The program for Astrobiology Science Conference 2010, which includes an amazing array of short summary papers for the presentations and abstracts*, can be found here.)

Among the many intriguing topics addressed was the current state of investigation into the 4 billion year old meteorite discovered in Antarctica which some scientists claimed 14 years ago to show evidence of microscopic life on Mars. The claim, quite naturally, engendered considerable controversy. The NASA team which has continued to assess the claim contends that “we’re now in a position to say we’ve knocked down all the criticisms — and our biological explanation is the one left standing.”

See Marc Kaufman’s NASA Team Cites New Evidence That Meteorites from Mars Contain Ancient Fossils in the Washington Post.

* Many of these short summary papers are extremely interesting. I recommend them to any who may be curious.
