Assessing slope uncertainties of martian Digital Elevation Models from numerical propagation of errors on synthetic geological surfaces

C. Millot et al.

Summary: Digital Elevation Models (DEMs) are widely used in planetary sciences, including for Mars. They provide necessary topography parameters for geomorphological studies. However, DEMs are not free from vertical errors, leading to uncertainties in calculating parameters such as local slopes. Slope maps computed from DEMs often display slope patterns unrelated to the original images, which may originate from DEM vertical errors. To investigate this, a numerical method is proposed to quantitatively analyze slope errors based on DEM error propagation using synthetic models. The method reveals that vertical errors in DEMs can generate slope patterns similar to those observed. Estimates of slope errors are also provided for four martian cameras, aiming to constrain local slope uncertainties in geomorphological studies.

Hargraves Crater, Mars: Insights into the internal structure of layered ejecta deposits

Leah E. Sacks et al.

Summary: Impact craters and their ejecta deposits provide insights into the structure and composition of planetary crusts. The Hargraves Crater on Mars exhibits a unique balance of exposure and preservation in its ejecta deposits. The crater has two distinct ejecta units, with the lower unit interpreted as lithic impact breccia and the overlying unit as impact melt-bearing breccia or impact melt rock unit. The sharp contact between these two units is similar to observations of ejecta deposits on Earth. Study of Hargraves-type ejecta will improve our understanding of ejecta and ejecta emplacement processes.

Digital elevation model workflow improvements for the MarsSI platform and resulting orthorectified mosaic of Oxia Planum, the landing site of the ExoMars 2022 rover

Matthieu Volat et al.

Summary: In this publication, the study focuses on improving the quality and speed of DEM generation procedures from stereo-photogrammetry pipeline of the MarsSI online service. A new workflow relying on semi-global matching algorithms and a two steps approach is proposed, resulting in artifacts/noise reduction in the products and improved co-registration of the outputs. This new workflow is used in the production of mosaic of ground models and orthorectified images, as illustrated with the example of the orthorectified HiRISE images mosaic in the Exomars project.

Insight Into Formation Processes of Layered Ejecta Craters on Mars From Thermophysical Observations

R. H. Hoover et al.

Summary: Understanding the morphological characteristics of LE craters on Mars can provide insights into their formation processes, particularly the volatile fluidization model and atmospheric entrainment model. Thermal analysis of 50 LE craters revealed varying grain size distributions, with some craters matching specific models while others do not, indicating uncertainty in model classification.

Morphologic differences in radial grooves on martian layered (fluidized) ejecta: Implications for emplacement processes and conditions

Joseph M. Boyce et al.

Summary: This study conducted a detailed morphologic and morphometric analysis of the radial grooves on Martian layered ejecta, proposing three different categories of grooves in correlation with different types of ejecta craters. The findings suggest that the formation of these grooves is closely related to geological processes and eruption mechanisms.
