Very cool news indeed! I've always thought that life at one point existed on Mars. Maybe not aliens like on TV, but microbial organisms that could have flourished years ago. Very exciting news!
The cool thing about this discovery was that this rover can only drill about 5cm into a rock sample. The new Euro Mars rover in a couple years will be able to drill 2 meters down. A much more significant distance. A distance where possible organic material would be much more well preserved.
