Große organische Polymermoleküle auf dem Mars könnten eines der bisher besten Lebenszeichen sein

So far, there has not been one single set of „extraordinary evidence“ that proves conclusively there was once life on Mars, but the weight of evidence is piling up, and the vast majority of it points to life on Mars in the distant past.

The Yellowknife samples (2013) were some of the first samples that Curiosity analyzed. Of course JPL tried to set it down in a really good place to look, just in case the rover failed early, but to me it looks as if they really hit the jackpot with the Yellowknife samples and images, which include possible stromatolites.
