QUOTE he latest results from Mars Express reveal that the surface of the red planet is much more diverse than previously thought, with evidence for the presence of hydrated sulphates, silicates and various rock-forming minerals. Space scientists working on the European Space Agency mission have just analysed the first nine months of data from the OMEGA instrument and published six papers that give the first detailed inventory of the entire Martian surface. Last year Mars Express identified frozen water at both the north and south poles of the planet.

New press release. "The flood after the impact".
Like the commenters, I think the description is wrong. The crater came after the river, not the other way around. Even a non-geologist like me can see that the river flowed from left to right, towards the crater. And a quick look in Google-mars clearly shows where the riverbed originated; a fissure to the south, not that crater. Also, this is Hebrus Valles, not Hephaestus Fossae. |

... Even a non-geologist like me can see that the river flowed from left to right, towards the crater.... You may well be right. However as this non-geologist sees it, if an impact melts a large area of subsurface ice, the rivers formed will flow downhill whether that is toward or away from the crater. And the water from the subsurface melt will escape to the surface via the route of least resistance which may be a preexisting fissure. |
