Abstract The intense plume activity at the South Pole of Enceladus together with recent detection libration hints an internal water ocean underneath outer ice shell. However, interpretation gravity, shape, and data leads to contradicting results regarding depth ocean/ice interface total volume ocean. Here we develop interior structure model consisting a rocky core, ocean, shell, which satisfies simultaneously data. We show that can be reconciled by considering isostatic compensation...
Thousands of phyllosilicate‐rich outcrops, mainly iron or magnesium‐rich are exposed on Noachian terrains in the Martian southern highlands. We analyzed 90 CRISM observations and more than a hundred HiRISE images located plateaus surrounding Valles Marineris. mapped an extensive Al‐ Fe/Mg‐phyllosilicate‐rich formation covering at least ∼197,000 km 2 , for which we introduce name “Plateau Phyllosilicates.” Tens meters thickness, this light‐toned crops out various elevations top units Npl 1 as...
Jezero crater has been selected as the landing site for Mars 2020 Perseverance rover, because it contains a paleolake with two fan-deltas, inlet and outlet valleys. Using data from High Resolution Stereo Camera (HRSC) Imaging Science Experiment (HiRISE), we conducted quantitative geomorphological study of valleys paleolake. Results show that strongest erosion is related to network deep cut into highland bedrock well upstream likely formed before formation regional olivine-rich unit. In...
Aram Chaos is a crater 280 km in diameter centered at 2.5°N, 338.5°E. It filled by chaotic terrains overlain dome‐shaped, layered 900 m thick formation displaying spectral signatures of ferric oxides on Thermal Emission Spectrometer (TES) and Observatoire pour la Mineralogie, L'Eau, les Glaces et L'Activite (OMEGA) medium spatial resolution data. We describe detail the mineralogical composition, structure, morphology this fill using high‐resolution data (OMEGA, Mars Orbiter Laser Altimeter,...
Abstract We describe and compare the morphology activity of two types gullies with different orientations collocated on Kaiser dune field in southern hemisphere Mars: large apron linear gullies. The follows an annual cycle: (i) material collapse into alcove (mid-autumn/late winter) as CO 2 condenses; (ii) remobilization by mass flows (late winter); (iii) continuous appearance hundreds ‘digitate flows’ fan (autumn/winter). find that could form Martian years. In contrast, are active briefly...
