Dust Activities of the Utopia Planitia
As a core component of the Martian climate system, dust activity not only profoundly shapes the Martian surface morphology but also influences key processes such as atmospheric mass exchange on Mars. Due to the low atmospheric pressure on Mars, sand and dust on its surface are easily lifted by wind, forming dust events of varying scales. Remote sensingZhibin Li +10 more

Evidence for large reservoirs of water/mud in Utopia and Acidalia Planitiae on Mars
Icarus, 2015Abstract Utopia and Acidalia Planitiae show a set of similar morphologic features indicative of the presence of large reservoirs of water/mud in these regional topographic lows. The most important of these features are: (1) impact crater ejecta morphology that progressively changes from ballistic/rampart at the basins periphery to strongly degraded ...

Evidence, Age, and Thickness of a Frozen Paleolake in Utopia Planitia, Mars
Icarus, 1994Recent mapping studies west of Elysium Mons, Mars, have pinpointed subice features that suggest the existence of a frozen paleolake in Utopia Planitia as recently as 1.8 billion years ago. The subice features are interpreted to be hyaloclastic ridges and hills, table moutains, associated joekulhalaup deposits, and fluvial channels.

Investigating Martian Subsurface Features in Utopia Planitia With Tianwen-1 Ground-Penetrating Radar
IEEE Transactions on Geoscience and Remote SensingThis article deals with the investigation of the Martian subsurface in the Utopia Planitia region using Zhurong’s ground-penetrating radar. The low-frequency data recorded along the overall path followed by the rover are processed thanks to a customized signal processing pipeline aiming on one side to minimize the artifacts in the radargrams and, on ...

Thermokarst processes and the origin of crater-rim gullies in Utopia and western Elysium Planitia
Icarus, 2007Abstract We have identified a number of gullies that could be aqueous in origin near or at the rim of several impact craters in Utopia Planitia and western Elysium Planitia (30.0°–59.0° N; 241.0°–291.0° W). Based on the sharpness of their incisions and the general absence of superposed craters, we ascribe a relatively recent origin to the gullies ...

Martian thermal-contraction polygons as sounders of subsurface properties in Utopia Planitia
On Earth, temperature decreases can cause the thermal contraction of ice-cemented ground. This forms polygonal networks of surficial fractures – called ‘thermal-contraction polygons’ (Washburn, 1956). Polygons exhibit different morphologies with time (Black, 1954): initially showing no relief (‘flat-centred ...Susan Conway +3 more

Spectral evidence of hydrous minerals and water ice on southern Utopia Planitia, Mars
Previous mineralogical investigations on Utopia Planitia only show sporadic hydrous minerals in localized areas, limiting the modeling of the regional aqueous activities. Although the periglacial landforms and radar observations allude to the presence of subsurface water ice in Utopia Planitia, evidence of water ice on the surface is not detected ...Mi Song +3 more
