updated the description of Special Regions on Mars as places where terrestrial organisms …

Planetary mapping product established by topographic remote sensing is one of the most
significant achievements of contemporary technology. Modern planetary remote sensing …

This review paper summarizes the observations and results of the Mars Express Mission
and its application in the analysis of geological processes and landforms on Mars during the …

Self-consistent landform assemblages suggest that Valles Marineris, the giant valley system
that stretches along the Martian equator, was entirely glaciated during Late Noachian to …

Flat-floored depressions with scalloped-shapes and spatially associated small-sized
polygons (diameter<∼ 100m) dot the landscape of western Utopia Planitia (centered at 45° …

Elysium Planitia includes several outflow channels that were likely carved by aqueous
erosion and subsequently infilled by younger lava flows, making Elysium Planitia the …

Investigations of Mars as a potential location for life often make the assumption that where
there are habitats, they will contain organisms. However, the observation of the ubiquitous …

Self-organised patterns of stone stripes, polygons, circles and clastic solifluction lobes form
by the sorting of clasts from fine-grained sediments in freeze–thaw cycles. We present new …

On Earth, the thawing of permafrost deposits with high‐ground ice content results in massive
surface subsidence and the formation of characteristic large thermokarst depressions. Slope …

Abstract Periglacial landforms on Spitsbergen (Svalbard, Norway) are morphologically
similar to landforms on Mars that are probably related to the past and/or present existence of …
