Kind of old news by now I guess, but space.com has the story. It is a seriously important discovery though - perhaps much more important than it seems. First, of course, it means we can send a manned mission to mars - and then they can get home again. Second, if there’s enough then we can set up a self-sustaining presence on Mars (as long as someone fancies shelling out the money of course).
Finally, though, it has to alter our estimates for the presence of life not just on Mars, but everywhere. With only one data-point, Earth, it has been basically impossible to extrapolate the chances of there being life anywhere. But the more we discover about the universe, the more likely it seems there is life all over the place.
Of course this just makes the Fermi Paradox even more terrifying!
