Dust Devil Tracks [PDF]

, 2016
Dust devils that leave dark- or light-toned tracks are common on Mars and they can also be found on the Earth’s surface. Dust devil tracks (hereinafter DDTs) are ephemeral surface features with mostly sub-annual lifetimes.

Martian impact crater ejecta morphologies as indicators of the distribution of subsurface volatiles [PDF]

, 2003
Fresh Martian impact craters display a variety of ejecta blanket morphologies. The fluidized appearance of most fresh ejecta types is commonly ascribed to heating and vaporization of subsurface volatiles during crater formation.

An Inclusive Library for Quantitative Analysis of the Laser-induced Breakdown Spectra Acquired by the Zhurong Mars Rover

The Astrophysical Journal
Laser-induced breakdown spectroscopy (LIBS) is a critical tool for geochemical analysis in planetary science due to its ability to remotely detect a broad range of elements at submillimeter spatial resolution.

Chemical evolution of the early Martian hydrosphere [PDF]

The chemical evolution of the early Martian hydrosphere is discussed. The early Martian ocean can be modeled as a body of relatively pure water in equilibrium with a dense carbon dioxide atmosphere. The chemical weathering of lavas, pyroclastic deposits,

Geological analysis of the dome field in western Utopia Planitia, on Mars

Icarus
Hundreds of domes are scattered over a plain composed of different geological units in the western margin of Utopia Planitia, near the northern martian dichotomy. These structures have traditionally been considered of igneous origin. In this work, we utilized recent data to study the geomorphological and compositional properties of this dome field.

Evidence for glaciation in Elysium [PDF]

It is suggested that certain landforms in the Elysium region of Mars provide strong evidence for glaciation. Landscapes related to subglacial volcanism suggest that ice was a primary agent in the development of ...

Martian Subsurface Properties and Crater Formation Processes Inferred From Fresh Impact Crater Geometries [PDF]

, 2011
The geometry of simple impact craters reflects the properties of the target materials, and the diverse range of fluidized morphologies observed in Martian ejecta blankets are controlled by the near-surface composition and the climate at the time of ...
