The photographs taken by the Mars Global Surveyor has scientists excited about the possibility of water on Mars

A new study of photographs have revealed that bright new deposits observed in gullies on the planet Mars may prove that water carried sediment through them sometime recently, according to NASA.  The U.S. space agency believes it has found "compelling" evidence that liquid water once existed on the surface of Mars.

The recent images were taken by NASA's Mars Global Surveyor space probe.  The discovery is important because it might help prove that the Red Planet has an environment that is favorable for living beings.  Just trying to find remote signs of liquid water on Mars has been a goal among scientists around the world for a number of years.  

The cameras on the Mars Global Surveyor were the first to take images that initially suggested water once flowed on Mars.  Scientists then went and searched valleys in search for conclusive evidence of water flow.  Just like most reports regarding Mars, there is some debate as to whether or not it really was liquid water -- some scientists claim that liquid carbon dioxide may have cut the gullies.

The findings by researchers were published today in the journal Science – NASA held a news conference to announce the results of the study.  The idea that water recently flowed on Mars is another piece of the puzzle that NASA is trying to put together about the still very foreign Red Planet.

That's what I thought, but it could be half way around the planet like thousands of miles, and over impassable mountain terrain and craters at SLOW speed, assuming they have enough battery/solar, and assuming the tyres don't wear out.

I think they would likely need to send a new probe from earth and target it to land in the valley line region.

I did think that an autonomous well-driller hole boring tool on the rover would let us see if there is any watertable or secrets underground. Also ground penetrating radar to do geological surveys.

The rover might be a few meters away but cant get closer to take some pictures because it fell into a ocean..
