Ancient fossilized soils potentially found deep inside impact crater suggest microbial life

Volume 1, Issue 7

Soil deep in a crater dating to some 3.7 billion years ago contains evidence that Mars was once much warmer and wetter, says a geologist based on images and data captured by the rover Curiosity. The ancient soils do not prove that Mars once contained life, but they do add to growing evidence that an early wetter and warmer Mars was more habitable than the planet has been in the past 3 billion years.

Curiosity rover is now exploring topographically higher and geologically younger layers within the crater, where the soils appear less conducive to life.
