The Mars Express High Resolution Stereo Camera (HRSC) captured this view of Mars' Tharsis volcanic region on June 29, 2014 during its 13,323rd orbit of the planet. This image uses low-resolution blue, green, and IR color data (with green and IR blended 50-50 to produce a synthetic red image) overlaid on a high-resolution clear filter image. Olympus Mons is at center. Across top center from left to right are Ascraeus Mons, Pavonis Mons, and Arsia Mons. Noctis Labyrinthus can be seen near the horizon at top left.
