Abstract The presence and distribution of preserved organic matter on the surface Mars can provide key information about Martian carbon cycle potential planet to host life throughout its history. Several types molecules have been previously detected in meteorites 1 at Gale crater, 2–4 . Evaluating diversity detectability elsewhere is important for understanding extent processes availability sources 1,5,6 Here we report detection Raman fluorescence spectra consistent with several species...
Abstract The first samples collected by the Mars 2020 mission represent units exposed on Jezero Crater floor, from potentially oldest Séítah formation outcrops to youngest rocks of heavily cratered Máaz formation. Surface investigations reveal landscape‐to‐microscopic textural, mineralogical, and geochemical evidence for igneous lithologies, some possibly emplaced as lava flows. contain major rock‐forming minerals such pyroxene, olivine, feldspar, accessory including oxides phosphates,...
Abstract Troughs carved into Mars' polar ice cap expose layers of different brightness and topography. These can be divided two strata types: darker, higher dust content marker beds brighter, lower interbeds. In a companion paper (Pascuzzo et al., 2025, https://doi.org/10.1029/2024JE008377 ), we measure the topographic protrusion Here, investigate processes factors that contribute to evolution these gain insight sublimation rates timescales for active trough wall retreat, specifically...
Abstract The Mars 2020 Perseverance rover has explored fluvio‐lacustrine sedimentary rocks within Jezero crater. Prior work showed that igneous crater floor Séítah and Máaz formations have mafic mineralogy with alteration phases indicate multiple episodes of aqueous alteration. In this work, we extend the analyses hydration to targets in western fan delta, using data from SHERLOC (Scanning Habitable Environments Raman Luminescence for Organics Chemicals) spectrometer. Spectral features,...
Abstract Mars' north polar ice cap features troughs that cut into the ice, exposing subsurface layers of different brightness and topographic expression. Specifically, these represent two stratum types: lower albedo (higher dust content) marker beds, which protrude out wall topographically, higher (i.e., icier) interbeds, are recessed compared to beds. Here, we investigate role local‐scale processes by performing a detailed geomorphic characterization variability in strata across sites,...
Abstract Motivated by recent evidence for subduction in Europa's ice shell, we explore the geophysical feasibility of this process. Here construct a simple model to track evolution porosity and temperature within slab that is forced subduct. We also vary initial salt content shell determine buoyancy our simulated subducting slab. find play dominant role determining whether nonbuoyant actually possible. Generally, initially low porosities high contents conductive lid are more conducive...
Abstract Several mineralogically diverse regions across Mars are capped by dark‐toned rock formations emplaced during the Noachian‐Hesperian transition, an era encompassing a shift in volcanism from dominantly explosive to effusive. However, these caprocks' origins uncertain, limiting insight into nature of this shift. We explore potential volcanic ash origin widespread (∼50,000 km 2 ) mafic caprock Circum‐Isidis region via integrated photogeologic and remote‐compositional analysis. also...
The Mars 2020 Perseverance rover is equipped with 23 cameras that aid in science operations and investigations [1]. on image from the scale of tens meters down to microns, enabling detailed visual analysis martian surface across spatial scales. Some these are co-boresighted spectrometers, allowing for acquisition spatially resolved compositional data. Integrating images multiple different a challenge due differences such as angle acquisition, illumination, resolution, pixel scale. However,...
Abstract During its first year of operation, the Perseverance rover explored cratered and fractured floor Jezero crater on Mars. Here, we report use Scanning Habitability Environments with Raman Luminescence for Organics Chemicals (SHERLOC) imaging system that includes two high‐resolution cameras, Autofocus Contextual Imager (ACI) Wide Angle Topographic Sensor Operations eNgineering (WATSON). ACI is a fixed focus gray scale imager resolution 10.1 μm/pixel whereas WATSON variable field view,...
Abstract Mars Polar Science is a subfield of science that encompasses all studies the cryosphere and its interaction with Martian environment. Every 4 yr, community scientists dedicated to this meets discuss new findings debate open issues in International Conference on Exploration (ICMPSE). This paper summarizes proceedings seventh ICMPSE progress made since sixth edition. We highlight most important advances present salient questions field today, as discussed agreed upon by participants...
Abstract Data returned from the Cassini–Huygens mission have strengthened Enceladus, a small icy moon of Saturn, as an important target in search for life our solar system. Information gathered Cassini to support this includes presence subsurface liquid water ocean, vapor plumes and ice grains emanating its south polar region, detection essential elements organic material that could potentially life. However, several outstanding questions remain regarding connectivity plume ocean composition...
