5.8.2010 | Mars: The New Evidence

Obsah epizody

A look for evidence of life on Mars which provides many clues that it now, or once had supported it; from the remains of lakes and rivers that once flowed on the surface; to the water ice frozen at the poles; to the seasonal changes in methane gases that may prove bacterial life still thrives underground.
