Water-rich impact crater on Mars

Colour view of crater north of the Hellas basin. The crater is 32 km-wide and was formed at time when the martian environment was much wetter, as seen in the fluidised nature of the debris excavated from it.

The images were acquired by the High Resolution Stereo Camera on Mars Express on 3 May 2017 during orbit 16890. The ground resolution is approximately 21 m/pixel and the images are centred on 70°E/22°S. In this orientation, north is to the right.

The colour image was created using data from the nadir channel, the field of view which is aligned perpendicular to the surface of Mars, and the camera’s colour channels.
