Ceraunius Tholus and Uranius Tholus are two volcanoes in the Tharsis region of Mars. Ceraunius Tholus is 130 km across and rises 5.5 km above its surroundings. The flanks of this volcano are etched with many valleys. Its neighbour, Uranius Tholus is a smaller volcano, with a base diameter of 62 km and a height of 4.5 km.

This image is derived from data acquired during three separate orbits of Mars Express, which took place between 25 November 2004 and 22 June 2006. During the second orbit, Mars Express’s camera captured icy clouds drifting past the summit of Ceraunius Tholus. In the finished mosaic image there is a sharp line because the clouds had long since dispersed by the time Mars Express crossed again and took the final strip of data needed for the image.

A wider contextual image showing the region around Ceraunius Tholus and Uranius Tholus. Together with Uranius Patera, a large volcano 120 km to the northeast, the volcanoes form the Uranius group. They are aligned with three large volcanoes known collectively as the Tharsis Montes. One of them, Ascraeus Mons, can be seen in the bottom left of this image. The others are Pavonis and Arsia. The Mars Express data were acquired in the Tharsis region at approximately 25°N / 263°E.

Ceraunius Tholus and Uranius Tholus are two volcanoes in the Tharsis region of Mars. The flanks of Ceraunius Tholus display deeply incised valleys of which the longest and deepest is about 3.5 km wide and 300 m deep [box 1]. This valley terminates with a fan of deposited material in the northern end of the elongated Rahe crater. The crater itself [box 2] is 35 km by 18 km and was created by the oblique impact of a meteorite. Other impacts have scarred this region, too. One in particular has ejected material over the flanks of the smaller volcano [box 3].

This image has been derived from data acquired during three separate orbits of Mars Express, which took place between 25 November 2004 and 22 June 2006.

HI-RES JPEG (Size: 408 kb)

HI-RES TIFF (Size: 73 854 kb)

Ceraunius Tholus and Uranius Tholus are two volcanoes in the Tharsis region of Mars. Ceraunius Tholus is 130 km across and rises 5.5 km above its surroundings. Its neighbour, Uranius Tholus is a smaller volcano, with a base diameter of 62 km and a height of 4.5 km. The image was created using a Digital Terrain Model (DTM) obtained from the High Resolution Stereo Camera on ESA’s Mars Express spacecraft. Elevation data from the DTM is colour coded: purple indicates the lowest lying regions and grey the highest. The scale is in metres.

ESA’s Mars Express obtained the image data in orbits 1096, 1107_1 and 3144, which took place between 25 November 2004 and 22 June 2006. The image has a resolution of approximately 13 m per pixel and was derived from the High Resolution Stereo Camera nadir channel, which provides the highest detail of all the channels.

Ceraunius Tholus is 130 km across and rises 5.5 km above its surroundings. Its flanks display deeply incised valleys of which the longest and deepest is about 3.5 km wide and 300 m deep. It terminates with a fan of deposited material in the north of the Rahe crater. The crater itself is 35 km by 18 km and was created by the oblique impact of a meteorite. The High Resolution Stereo Camera on ESA’s Mars Express took this image. The perspective view has been calculated from the digital terrain model derived from the stereo channels.

Ceraunius Tholus and Uranius Tholus are two volcanoes in the Tharsis region of Mars. Ceraunius Tholus is 130 km across and rises 5.5 km above its surroundings. Its neighbour, Uranius Tholus is a smaller volcano, with a base diameter of 62 km and a height of 4.5 km. The High Resolution Stereo Camera (HRSC) on ESA’s Mars Express took this image. It combines data from HRSC’s nadir channel and one stereo channel to produce this 3D image. Stereoscopic glasses are required to see the 3D effect.
