Does water still flow on Mars? These dramatic new photos seem to indicate yes
The images - released for the first time on Wednesday by the US space agency NASA - were taken earlier this year in an attempt to unlock the secrets of the Red Planet.
Experts have long believed water was to be found on Mars, which is subject to extreme weather conditions. This latest discovery may provide vital proof there was life on Mars and that it is possible for man to land on its arid and rocky surface.
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.
