Such as the Tardigrade ("Water Bear") [wikipedia.org]...
Tardigrades are able to survive in extreme environments that would kill almost any other animal. Some can survive temperatures of close to absolute zero (273 C (459 F)), temperatures as high as 151 C (304 F), 1,000 times more radiation than other animals, and almost a decade without water. Since 2007, tardigrades have also returned alive from studies in which they have been exposed to the vacuum of outer space for a few days in low earth orbit.
It seems to me that organisms like this would be able to survive on Mars, even in it's current conditions, so it seems to me that we're going to discover some form of elementary life on Mars eventually, it's just a matter of time (and looking in the right places, which could be miles below the surface for all we know).
Still, as a layperson that reads stuff like this as a hobby, I think we'd discover life on Europa [wikipedia.org] first...if we ever manage to figure out a way to get a probe under the ice (and of course keep it completely sterile, which given the hardiness of those water bears would seem to be damn hard to do beyond any shred of doubt for an earth-originating probe).
