Mars Express
Kasei Vallis
18 February 2004

This vertical view shows the mouth of Kasei Vallis, one of the largest outflow
channels on Mars, taken by Mars Express.
 
The image was taken by the High Resolution Stereo Camera (HRSC) on board
Mars Express during orbit 61 from an altitude of 272 km. The resolution is 12
metres per pixel. The image centre is located at 29.8° north and 309° east, the
image width is 130 km, North is up.

The part of the outflow channel seen in this image has most probably been
carved by glaciers or gigantic water-related outflows. The blackish-blue colour
is related to sediments. The bright streaks oriented NE-SW are related to wind
forces.

This image shows various details which give an insight into the erosional history
of the outflow channel. The image also illustrates how difficult it is to achieve
near-true colour in images of Mars when atmospheric dust and haze have a
major disturbing influence on the scene.
