Probing the Hidden Geology of Isidis Planitia (Mars) with Impact Craters

open access: yesGeosciences, 2015
In this study we investigated Isidis Planitia, a 1325 km diameter multi-ring impact basin intersecting the Martian hemispheric dichotomy, located in the eastern hemisphere, between Syrtis Major and Utopia Planitia.

Estimation of surface water content at the Tianwen-1 Zhurong landing site

open access: yesEarth and Planetary Physics, 2023
China’s first Mars rover, Zhurong, successfully landed in the south of Utopia Planitia. The surface water content at the landing area can provide constraints on mineral formation conditions and help us better understand the evolution of the Martian ...

Spatial Autocorrelation of Martian Surface Temperature and Its Spatio-Temporal Relationships with Near-Surface Environmental Factors across China’s Tianwen-1 Landing Zone

open access: yesRemote Sensing, 2021
Variations in the Martian surface temperature indicate patterns of surface energy exchange. The Martian surface temperature at a location is similar to those in adjacent locations; but, an understanding of temperature clusters in multiple locations will ...

Ice-rich (periglacial) vs icy (glacial) depressions in the Argyre region, Mars: a proposed cold-climate dichotomy of landforms [PDF]

open access: yes, 2017
On Mars, so-called “scalloped depressions” are widely observed in Utopia Planitia (UP) and Malea Planum (MP). Typically, they are rimless, metres- to decametres-deep, incised sharply, tiered inwardly, polygonised and sometimes pitted.

Observation-based temperature field simulation at Zhurong landing site, Mars

open access: yesFrontiers in Astronomy and Space Sciences, 2022
Modeling the temperature field near the Martian surface is critical for many scientific exploration tasks, such as detecting liquid water and analyzing the existence of saline ice.

The Periglacial Landscape Of Utopia Planitia; Geologic Evidence For Recent Climate Change On Mars.

open access: gold, 2013
The northern plains of Utopia Planitia, Mars, hosts an abundance of potential periglacial landforms including scalloped depressions, gullies, and polygon networks. This research was undertaken to investigate the distribution and stratigraphy of scalloped depressions in Utopia Planitia and to reconstruct the past environment in which this periglacial ...

Clastic Polygonal Networks Around Lyot Crater, Mars: Possible Formation Mechanisms From Morphometric Analysis [PDF]

open access: yes, 2017
Polygonal networks of patterned ground are a common feature in cold-climate environments. They can form through the thermal contraction of ice-cemented sediment (i.e. formed from fractures), or the freezing and thawing of ground ice (i.e.

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

open access: yesJournal 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).

Martian pedestal craters: Marginal sublimation pits implicate a climate-related formation mechanism [PDF]

open access: yes, 2008
Pedestal craters on Mars are defined by an outward-facing scarp forming a plateau perched tens of meters above the surrounding terrain. Their origin has been attributed to impact armoring of the surface and subsequent removal of inter-crater terrain by ...

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

open access: yesJournal 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.
