Orbital evidence for more widespread carbonate‐bearing rocks on Mars

Wray, James J Murchie, Scott L Janice Bishop Ehlmann, Bethany L Milliken, Ralph E Wilhelm, Mary Beth Seelos, Kimberly D

Published in Journal of Geophysical Research: Planets

Carbonates are key minerals for understanding ancient Martian environments because they are indicators of potentially habitable, neutral-to-alkaline water and may be an important reservoir for paleoatmospheric CO 2. Previous remote sensing studies have identified mostly Mg-rich carbonates, both in Martian dust and in a Late Noachian rock unit circu...

Stratigraphy and formation of clays, sulfates, and hydrated silica within a depression in Coprates Catena, Mars

Weitz, Catherine M Janice Bishop

Published in Journal of Geophysical Research: Planets

We investigate the morphology, mineralogy, and stratigraphy of light-toned layered deposits within a trough of Coprates Catena, centered at− 15 N, 300 E. One of the deposits in the eastern portion of the trough contains numerous hydrated minerals, including Al- phyllosilicates, Fe/Mg-phyllosilicates, hydrated silica, hydrated sulfates, jarosite and...

History of the clay‐rich unit at Mawrth Vallis, Mars: High‐resolution mapping of a candidate landing site

Loizeau, D Mangold, N Poulet, F Bibring, J‐p Janice Bishop Michalski, J Quantin, C

Published in Journal of Geophysical Research: Planets

The Mawrth Vallis region is covered by some of the largest phyllosilicate-rich outcrops on Mars, making it a unique window into the past history of Mars in terms of water alteration, potential habitability, and the search for past life. A landing ellipse had been proposed for the Curiosity rover. This area has been extensively observed by the High ...

Evidence for different episodes of aeolian construction and a new type of wind streak in the 2016 ExoMars landing ellips...

Silvestro, S Vaz, D A Di Achille, G Popa, I C Esposito, F

Published in Journal of Geophysical Research: Planets

We present evidence for a complex, multigenerational bed form pattern and a new type of wind streak (the ripple streak) in the landing site ellipse of the 2016 ExoMars Entry descent and landing Demonstrator Module (EDM) in Meridiani Planum (Mars). We identified three main groups of bright-toned bed forms. Population 3, represented by NE-SW trending...
