Sumary of Traces of life on Mars may have been erased, according to NASA:

  • In 2011 the Curiosity Rover was sent to Mars to collect stones from a location where a lake used to exist.
  • The clay samples that the robot has found are an indication that at some point there was water on the red planet, since it is produced when rocky minerals wear out and rot after having contact with water, which is the key to the existence of life and a material that can store microbial fossils.
  • However, the clay samples Rover collected do not contain the elements scientists expected and instead found a high concentration of iron oxide, which would have obliterated any fossil traces.
