Heyo, thought you'd want to know that that viral "6 Martian sunrises, as seen by the HiRISE orbiter. Once again, not artist’s renditions." post you reblogged are in fact artist's renditions by Kees Veenenbos, who creates those renderings as a hobby. The images have his credit in the lower-left corner. The HiRISE camera on the Mars Reconnaissance Orbiter takes cool pictures, but they don't look like that.
