Mars teeming with Life?!

[Drifter]

Doing some amateur browsing of Google Mars a while back, the black staining of the geyser plumes near the South Pole caught my attention. Recently I toyed with the idea the staining might be coloured by algae/bacterias. 

FeS munching variety?

This research also jumped out from the Search engine - thought it worth sharing.

Anyone got any other details/evidence to confirm these findings? + possibly expand on them?

Is anyone else surprised by the degree of damage sustained by the Rover vehicle’s wheels shown in this article? 
Looking at pictures of new rovers under test ... it appears the wheels are now being made from specialised plastics - less likely to be denatured by corrosive elements.
