April 12, 2011
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.

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.
