Dan, I think you've mistaken a part of sunlit soil in Phil's image as white stuff.


Agreed.

Here's a flicker between sol 21 and 24 showing change (or, rather, lack of):


Ignore the color of the brightest part of the white stuff, it's overexposed. The small white chunk in sol 21 image appears to disappear in sol 24 (inset).

Microbes have survived on Earth for 90% of the planet's history despite all the climate change. Mars has had liquid oceans over long periods too.

They will easily be able to see bio-markers if they exist at this scale:

Long odds, but it's just possible these guys will be the first to see evidence of the Holy Grail they are after. And us too!
