Geomorphologic exploration targets at the Zhurong landing site in the southern Utopia Planitia of Mars

Earth and Planetary Science Letters, 2021
Abstract On May 15, 2021, Tianwen-1's rover Zhurong landed successfully at 109.926°E, 25.066°N, in southern Utopia Planitia on Mars. The Zhurong landing site contains a wide range of geomorphic exploration targets including troughs, raised ridges, pitted cones, mesas, sand dunes and crater ejecta.

Possible ice-wedge polygonisation in Utopia Planitia, Mars and its poleward gradient of latitude [PDF]

, 2020
<p><strong>Introduction</strong></p> <p>On Mars, polygonally patterned ground is widespread at the mid to high latitudes and it is accepted to result from thermal contraction of ice-cemented soil<sup>1</sup>. Low-centered polygons (LCPs), i.e.

Buried palaeo-polygonal terrain detected underneath Utopia Planitia on Mars by the Zhurong radar [PDF]

Nature Astronomy, 2023
As the largest basin on Mars, Utopia Planitia has both experienced and recorded variations of the Martian palaeoclimate. Layered subsurface structures have been identified by ground-penetrating radar in southern Utopia Planitia but lateral variations of ...

Basement controls on the scale of giant polygons in Utopia Planitia, Mars [PDF]

Journal of Geophysical Research: Planets, 2011
We investigate the role of buried basement topography in controlling the scale of the giant polygons of Utopia Planitia (49°N, 233°W), Mars. Thermal Emission Imaging System (THEMIS) Infrared Daytime image mosaics reveal ∼6 km average spacing of polygon troughs along selected basin‐radial transects.

Topography within circular grabens: Implications for polygon origin, Utopia Planitia, Mars [PDF]

Geophysical Research Letters, 2002
Very large, fracture‐bounded polygons occur in Acidalia and Utopia Planitiae, Mars. Two models for the origin of these large polygons postulate drape folding of a sedimentary cover material over an uneven buried surface, with the strain enhancement needed to explain the large size due to differential compaction.

Mud flows in the Southwestern Utopia Planitia, Mars

Icarus (New York, N.Y. 1962), 2021
AbstractHere we present the results of our mapping of a large field of landforms characterized by flow-like morphology in the southwestern part of Utopia Planitia. They have been previously interpreted as mud flows associated with a partly frozen muddy ocean [1,2].

A probable ancient nearshore zone in southern Utopia on Mars unveiled from observations at the Zhurong landing area [PDF]

Scientific Reports
The Chinese Mars rover Zhurong successfully landed in southern Utopia Planitia on Mars in May 2021. Previous research suggested a Hesperian ocean may have existed in the northern lowland on Mars.

Rift zone volcanism and associated cinder cone field in Utopia Planitia, Mars [PDF]

Journal of Geophysical Research: Planets, 2010
We analyzed a small cone field in SW Utopia Planitia that shows striking similarities to volcanic rift zones on Earth. This is of particular interest as the study area lies off any of the volcanic centers of Mars in the northern hemisphere lowlands and is surrounded by material of the Amazonian aged Vastitas Borealis Formation (VBF).

Observations of periglacial landforms in Utopia Planitia with the High Resolution Imaging Science Experiment (HiRISE) [PDF]

Journal of Geophysical Research: Planets, 2009
The region of western Utopia Planitia (80–105°E, 40–55°N) displays several types of landforms similar to Earth periglacial features, including scallop‐shaped depressions and networks of polygonal terrains. The scalloped depressions have been proposed to originate from thermokarstic processes such as sublimation and/or melting of near‐surface ground ice.

Localization and Surface Characterization by Zhurong Mars Rover at Utopia Planitia [PDF]

, 2021
Abstract China’s first Mars rover, Zhurong, has successfully touched down on the southern Utopia Planitia of Mars at 109.925° E, 25.066° N, and since performed cooperative multiscale investigations with the Tianwen-1 orbiter. Here we present primary localization and surface characterization results based on complementary data of the first 60 ...
