Ceraunius Tholus and Uranius Tholus in context

April 12, 2011
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.
