Flowers on Mars?

The climate on Mars is harsh.  The air pressure on the surface is far far less than what you experience at the top of Everest (it is about 1% of Earth's atmosphere).  Temperatures can occasionally be mild (at the equator, at noon), but are mostly freezing cold (-50 to -155 C).  So a photograph like this is not going to convince me:



And if flowers were growing out of the rocks, wouldn't the Mars Curiosity rover have picked up on microscopic life in the samples it had taken so far?  Still, what the Curiosity is finding is amazing and I look forward to more data in the future.

  1. How do we know it's not a piece of jetsom from years of unmanned missions? I'm skeptical too.
