ISRO celebrates the completion of one year of its Mangalyaan mission today. Here are some breathtaking pictures taken by its Mars Colour Camera (MCC).

Valles Marineris. It’s the largest Martian canyon about 4,000 km long, 200 km wide and 7 km deep. Picture taken on December 5, 2014 at a spatial resolution of 1.2 km from an altitude of 24,000 km.

Clouds over the Arsia Mons region of Mars. It’s one of the many large volcanic mountains on Mars. The image was taken at a spatial resolution of 556 m from an altitude of 10,707 km.

This picture of Valles Marineris shows the wall of the canyon and the dust that covers the Martian valley in end-January. Image taken at a spatial resolution of 300 m from an altitude of 5,797 km. 

Kinkora crater on Mars. Wind streaks seen in the image are due to wind erosion. Image taken at spatial resolution of 110 m from an altitude of 2,286 km. 

Superimposed photograph of craters on Mars. It shows that smaller craters are younger than the larger ones. Taken at a spatial resolution of 19 m from an altitude of 356 km.

This is a 3D view of a portion of Valles Marineris taken by the Mars Colour Camera that shows the highs and lows of the canyon.

The Eos Chaos region on Mars, located east of the Valles Marineris region. Photograph taken at a spatial resolution of 220 m from an altitude of 4,403 km.
