Malea Planum - Mars Express HRSC
Mars Express HRSC image of Mars' southern hemisphere, centered on Malea Planum. Malea Planum is a large volcanic province located along the southeastern side of the Hellas Basin (the large light region that fills most of the picture's left half). Malea Planum contains four large caldera complexes, two of which are clearly visible as large, rimless circular features just left of image center. Malea Patera is a caldera complex containing two nested basins. Amphitrites Patera is located just above it. The small cluster of dune fields just below image center are associated with a third caldera, Pityusa Patera. The final volcano, Peneus Patera, is located between Malea Patera and the Hellas Basin.
Malea Planum is the most poorly-studied of the large volcanic provinces on Mars, in part due to the large amount of periglacial modification that occurs at its far southern latitudes, as well as significant amounts of dust that have blown in from the Hellas Basin. In addition to Malea Planum Mars' south polar ice cap is visible at right, and the dark, largely dust-free terrain of southern Sabaea Terra is visible along the horizon at left.
