Curiosity Rover Discovers Ancient 'Building Blocks for Life' on Mars

June 08, 2018

Organic molecules are considered one of the basic building blocks of life. The compounds discovered on Mars could have been produced by living things, or they could have been food for those living things. This doesn’t constitute proof that life existed on Mars, though. Other processes that have nothing to do with living organisms can create organic compounds as well. Still, this discovery is very encouraging in the context of what we know about Mars in the distant past.
