Mars is not just red

Pictures taken by NASA’s Mars Reconnaissance Orbiter show Nili Fossae in the Mars’ northwest region and its bright colours.



Images were captured by the Mars Orbiter's HiRISE (High Resolution Imaging Science Experiment) camera



"Nili Fossae Trough is a huge crack in the surface of Mars", a NASA spokesperson explained. 

The colors are produced by the presence of minerals – such as carbonate, aluminum smectite, and iron oxides – in the crust, something that might have supported life in the past.
