By studying rocks blasted out of impact craters, ESA's Mars Express has found evidence that underground water persisted at depth for prolonged periods during the first billion years of the Red Planet's existence.
Impact craters are natural windows into the history of planetary surfaces - the deeper the crater, the further back in time you can probe.
In addition, rocks blasted out during the impact offer a chance to study material that once lay hidden beneath the surface.
