The effect of remote sensing resolution limits on aeolian sandstone measurements and the reconstruction of ancient dune fields on Mars: Numerical experiment using the Page Sandstone, Earth
Published: 2019-09-10
Subjects: Physical Sciences and Mathematics, Planetary Geology, Planetary Sciences
The distribution of cross-set thicknesses is important field-collected data for reconstructing ancient aeolian dune fields from the strata they accumulated, but most aeolian strata on Mars must be observed with remote sensing. We hypothesize that remote sensing resolution limits will affect cross-set thickness measurements and the dune field reconstructions that follow. Here, we test this [...]
A PCA-based framework for determining remotely-sensed geological surface orientations and their statistical quality

The orientations of planar rock layers are fundamental to our understanding of structural geology and stratigraphy. Remote-sensing platforms including satellites, unmanned aerial vehicles (UAVs), and LIDAR scanners are increasingly used to build three-dimensional models of structural features on Earth and other planets. Remotely-gathered orientation measurements are straightforward to calculate [...]
Mars Global Simulant MGS-1: A Rocknest-based open standard for basaltic martian regolith simulants
Published: 2018-06-04
Subjects: Physical Sciences and Mathematics, Planetary Geology, Planetary Sciences
The composition and physical properties of martian regolith are dramatically better understood compared to just a decade ago, particularly through the use of X-ray diffraction by the Curiosity rover. Because there are no samples of this material on Earth, researchers and engineers rely on terrestrial simulants to test future hardware and address fundamental science and engineering questions. Even [...]
