This false-colour image of Terby crater on Mars was derived from three HRSC colour channels and the nadir channel of the High Resolution Stereo Camera (HRSC) on board the DLR-operated Mars Express orbiter. The Terby crater region is of great scientific interest as sediments there reveal information on the role of water in the history of the planet.
The image data was obtained on 13 April 2007 during orbit 4199, with a ground resolution of approximately 13 m/pixel. The Sun illuminates the scene from the west (from above in the image).
Terby crater lies at approximately 27° south and 74° east. It is located at the northern edge of the Hellas Planitia impact basin in the southern hemisphere of Mars.
The crater, named after the Belgian astronomer Francois J. Terby (1846 – 1911), has a diameter of approximately 170 km. The scene shows a section of a second impact crater in the northern part of Terby crater.
