This vertical view shows the complex caldera at the summit of Olympus Mons on Mars, the highest volcano in our Solar System. Olympus Mons has an average elevation of 22 km and the caldera has a depth of about 3 km.

This is the first high-resolution colour image of the complete caldera of Olympus Mons. The colour image was taken from a height of 273 km in orbit 37 by the High Resolution Stereo Camera (HRSC) on ESA’s Mars Express on 21 January 2004. The view is centred at 18.3°N and 227°E. The image is about 102 km across with a resolution of 12 m per pixel. South is at the top.

This 3D view of the complete volcano has been derived from US Mars Orbiter Laser Altimeter (MOLA) topographic data superimposed with the Mars Orbiter Camera (MOC) wide-angle image mosaic.

This perspective view shows the southern part of the caldera (summit crater) of the Olympus Mons volcano on Mars. The image has been calculated from the digital elevation model derived from the stereo channels and combined with the nadir- and colour-channels of the High Resolution Stereo Camera (HRSC) on ESA’s Mars Express.

The scene reveals tongue-shaped mass-movement features in 3D on the southern wall.

The data has been retrieved from a height of 273 km in orbit 37 on 21 January 2004. The view is centred at 18.3°N and 227°E. The image is about 40 km across. The vertical exaggeration is 1.8. South is up.
