Networks of narrow ridges found in impact craters on Mars appear to be the fossilized remnants of underground cracks through which water once flowed, according to a new analysis. The study bolsters the idea that the subsurface environment on Mars once had an active hydrology and could be a good place to search for evidence of past life.
