Traces of water in Martian crater

Martian crater Lucaya named after the port in the Bahamas. 34-kilometer-long formation located South of the equator of the red planet and first glance little different from most of the Martian craters. But a group of researchers from the UK and Ireland, recently published an article in which he argued that it should look closely. According to them, not so long ago the crater was flooded with streams of water.

In favor of this theory they cite the MRO pictures of the device. They found formations resembling structures in the Namib desert. They occur when underground water is temporarily come to the surface. Of course the H2O evaporates quickly, but remaining on the surface of salt “holds” the sedimentary deposits and sand dunes. Something similar may have occurred in the crater Lucaya. And, judging by the freshness of the formations is relatively recent in geological terms and not even once.

As for where this place came from the water in liquid form, there are a couple of versions. First, the strike led to the formation of the crater could temporarily melt the subsurface ice. In this case, flooding would be a single that is certainly not so interesting. A more intriguing possibility is hydrothermal activity (optionally, triggered by this impact). If other scientists confirm the findings of colleagues, it is likely that the crater Lucaya will be the landing of a future Mars astrobiology stations.
