“Compelling Evidence of Life on Mars”

, ,


Meteorite of Martian origin thought to include a fossilized bacteria colony

NASA scientists are gradually becoming convinced that Mars at least used to harbor life.

The Telegraph:

A research team at Johnson Space Centre in Houston has been re-examining a meteorite that hit Antarctica 13,000 years ago, and found the most compelling evidence yet that the planet once harboured bacterial life.

The team says that microscopic crystals found in the rock are almost certainly fossilised bacteria that have many characteristics in common with bacteria found on Earth.

“The evidence supporting the possibility of past life on Mars has been slowly building up during the past decade,” said David McKay, Nasa chief scientist for exploration and astrobiology.
