Mars still has water?

At 1pm Eastern (10am Pacific), NASA will announce a "significant find on Mars." Not likely that it's little green men but rather evidence that water may still be flowing on the planet's surface. The discovery is based on photos taken from the Mars Global Surveyor. From the Daily Mail:

NASA researchers have documented the formation of new craters on the plant's surface and found bright, light-coloured deposits in gullies that were not present in previous photos.

They concluded the deposits – possibly mud, salt or frost – were left there when water recently cascaded through the channels.

In another photo a number of gullies on a crater wall can be clearly seen. The scientists believe that they may have been formed in relatively recent Martian history by erosion caused by flowing, liquid water.
