Mars Express HRSC images
Following its arrival at the Red Planet in December 2003, imagery from ESA’s ongoing Mars Express mission has proved immensely popular, with the High Resolution Stereo Camera (HRSC) on board the spacecraft playing a major role. Since January 2004, ESA and its partners at the German Aerospace Center (DLR) and the Freie Universität Berlin (FUB) have been jointly publishing colour, stereo pictures of the martian surface from orbit, both still and moving, which are available under the Creative Commons CC BY-SA 3.0 IGO licence and can be found at ESA space in images. More info is also available via the original blogpost.
