Life is known to adapt in accordance with its surrounding environment and sustainable resources available to it. Since harsh conditions would have precluded any possible aerobic evolution of life at the martian surface, it is plausible that martian life, should it exist, would have evolved in such a way as to derive energy from more optimum resour…

Morphological and Spectral Diversity of the Clay-Bearing Unit at the ExoMars Landing Site Oxia Planum
DOI: 10.1089/ast.2020.2292 Bibcode: 2021AsBio..21..464M

Pan, Lu; Quantin-Nataf, Cathy; Cremonese, Gabriele +10 more

The European Space Agency and Roscosmos' ExoMars rover mission, which is planned to land in the Oxia Planum region, will be dedicated to exobiology studies at the surface and subsurface of Mars. Oxia Planum is a clay-bearing site that has preserved evidence of long-term interaction with water during the Noachian era. Fe/Mg-rich phyllosilicates hav…

Fluvial Regimes, Morphometry, and Age of Jezero Crater Paleolake Inlet Valleys and Their Exobiological Significance for the 2020 Rover Mission Landing Site
DOI: 10.1089/ast.2019.2132 Bibcode: 2020AsBio..20..994M

Mangold, Nicolas; Quantin-Nataf, Cathy; Massé, Marion +5 more

Jezero crater has been selected as the landing site for the Mars 2020 Perseverance rover, because it contains a paleolake with two fan-deltas, inlet and outlet valleys. Using the data from the High Resolution Stereo Camera (HRSC) and the High Resolution Imaging Science Experiment (HiRISE), we conducted a quantitative geomorphological study of the …

Mawrth Vallis, Mars: A Fascinating Place for Future In Situ Exploration
DOI: 10.1089/ast.2019.2074 Bibcode: 2020AsBio..20..199P

Horgan, Briony; Poulet, François; Carter, John +4 more

After the successful landing of the Mars Science Laboratory rover, both NASA and ESA initiated a selection process for potential landing sites for the Mars2020 and ExoMars missions, respectively. Two ellipses located in the Mawrth Vallis region were proposed and evaluated during a series of meetings (three for Mars2020 mission and five for ExoMars…

Estimated Minimum Life Span of the Jezero Fluvial Delta (Mars)
DOI: 10.1089/ast.2020.2228 Bibcode: 2020AsBio..20..977S

Mangold, Nicolas; Salese, Francesco; Kleinhans, Maarten G. +4 more

The paleo-lake floor at the edge of the Jezero delta has been selected as the NASA 2020 rover landing site. In this article, we demonstrate the sequences of lake filling and delta formation and constrain the minimum life span of the Jezero paleo-lake from sedimentological and hydrological analyses. Two main phases of delta evolution can be recogni…
