Unusual structures in the Angustus Labyrinthus region
On 27 February 2024, DLR's HRSC Mars camera imaged the Angustus Labyrinthus region near the south pole of Mars. On a high plateau, several ridges a few kilometres in length run in a straight line and at right angles to each other. The resulting pattern was discovered as early as 1972 in images taken by NASA's Mariner 9 spacecraft, reminding scientists of the ruins of the Inca city of Machu Picchu in the Peruvian Andes. This is why the structure is still informally referred to in Mars research as 'Inca city'. Various processes are under discussion as to the origin of this structure.
