2. Properties of the Nili Fossae Olivine-clay-carbonate lithology: orbital and in situ at S\'e\'itah

Abstract: We examine the observed properties of the Nili Fossae olivine-clay-carbonate lithology from orbital data and in situ by the Mars 2020 rover at the S\'e\'itah unit in Jezero crater, including: 1) composition (Liu, 2022) 2) grain size (Tice, 2022) 3) inferred viscosity (calculated based on geochemistry collected by SuperCam (Wiens, 2022)). Based on the low viscosity and distribution of the unit we postulate a flood lava origin for the olivine-clay-carbonate at S\'e\'itah. We include a new CRISM map of the clay 2.38 {\mu}m band and use in situ data to show that the clay in the olivine cumulate in the S\'e\'itah formation is consistent with talc or serpentine from Mars 2020 SuperCam LIBS and VISIR and MastCam-Z observations. We discuss two intertwining aspects of the history of the lithology: 1) the emplacement and properties of the cumulate layer within a lava lake, based on terrestrial analogs in the Pilbara, Western Australia, and using previously published models of flood lavas and lava lakes, and 2) the limited extent of post emplacement alteration, including clay and carbonate alteration (Clave, 2022; Mandon, 2022)., Comment: 34 pages, 15 figures

Abstract: In the next decade, two rovers will characterize in situ the mineralogy of rocks on Mars, using for the first time near-infrared reflectance spectrometers: SuperCam onboard the Mars 2020 rover and MicrOmega onboard the ExoMars rover, although this technique is predominantly used in orbit for mineralogical investigations. Until successful completion of sample-return missions from Mars, Martian meteorites are currently the only samples of the red planet available for study in terrestrial laboratories and comparison with in situ data. However, the current spectral database available for these samples does not represent their diversity and consists primarily of spectra acquired on finely crushed samples, albeit grain size is known to greatly affect spectral features. We measured the reflected light of a broad Martian meteorite suite as a means to catalogue and characterize their spectra between 0.4 and 3 microns. These measurements are achieved using a point spectrometer acquiring data comparable to SuperCam, and an imaging spectrometer producing hyperspectral cubes similarly to MicrOmega. Our results indicate that point spectrometry is sufficient to discriminate the different Martian meteorites families, to identify their primary petrology based on band parameters, and to detect their low content in alteration minerals. However, significant spectral mixing occurs in the point measurements, even at spot sizes down to a few millimeters, and imaging spectroscopy is needed to correctly identify the various mineral phases in the meteorites. Bidirectional spectral measurements confirm their non-Lambertian behavior, with backward and suspected forward scattering peaks. With changing observation geometry, the main absorption strengths show variations up to 10-15 percents. All the spectra presented are provided in the supplementary data for further comparison with in situ and orbital measurements.

Abstract: We present the Infrared spectrometer of SuperCam Instrument Suite that enables the Mars 2020 Perseverance Rover to study remotely the Martian mineralogy within the Jezero crater. The SuperCam IR spectrometer is designed to acquire spectra in the 1.3-2.6 $\mu$m domain at a spectral resolution ranging from 5 to 20~nm. The field-of-view of 1.15 mrad, is coaligned with the boresights of the other remote-sensing techniques provided by SuperCam: laser-induced breakdown spectroscopy, remote time-resolved Raman and luminescence spectroscopies, and visible reflectance spectroscopy, and micro-imaging. The IR spectra can be acquired from the robotic-arm workspace to long-distances, in order to explore the mineralogical diversity of the Jezero crater, guide the Perseverance Rover in its sampling task, and to document the samples' environment. We present the design, the performance, the radiometric calibration, and the anticipated operations at the surface of Mars., Comment: Accepted for publication in Icarus

7. Likely Ferromagnetic Minerals Identified by the Perseverance Rover and Implications for Future Paleomagnetic Analyses of Returned Martian Samples.

Abstract: Although Mars today does not have a core dynamo, magnetizations in the Martian crust and in meteorites suggest a magnetic field was present prior to 3.7 billion years (Ga) ago. However, the lack of ancient, oriented Martian bedrock samples available on Earth has prevented accurate estimates of the dynamo's intensity, lifetime, and direction. Constraining the nature and lifetime of the dynamo are vital to understanding the evolution of the Martian interior and the potential habitability of the planet. The Perseverance rover, which is exploring Jezero crater, is providing an unprecedented opportunity to address this gap by acquiring absolutely oriented bedrock samples with estimated ages from ∼2.3 to >4.1 Ga. As a first step in establishing whether these samples could contain records of Martian paleomagnetism, it is important to determine their ferromagnetic mineralogy, the grain sizes of the phases, and the forms of any natural remanent magnetization. Here, we synthesize data from various Perseverance instruments to achieve those goals and discuss the implications for future laboratory paleomagnetic analyses. Using the rover's instrument payload, we find that cored samples likely contain iron oxides enriched in Cr and Ti. The relative proportions of Fe, Ti, and Cr indicate that the phases may be titanomagnetite or Fe‐Ti‐Cr spinels that are ferromagnetic at room temperature, but we cannot rule out the presence of non‐ferromagnetic ulvöspinel, ilmenite, and chromite due to signal mixing. Importantly, the inferred abundance of iron oxides in the samples suggests that even <1 mm‐sized samples will be easily measurable by present‐day magnetometers. Plain Language Summary: Mars today does not have a magnetic field, but laboratory studies of Martian meteorites and spacecraft observations of the Martian crust indicate that Mars's metallic core once generated a magnetic field, known as a core dynamo. Although the dynamo seems to have been active prior to ∼3.7 billion years ago, its strength, direction and lifetime are largely unknown. Determining these characteristics is important for understanding the evolution of the Martian core and to test the theory that the magnetic field played a key role in making ancient Mars habitable. The Perseverance rover is providing a unique opportunity to answer these questions by acquiring bedrock samples that may span the full lifetime of the field. However, to establish whether these samples could tell us about the ancient dynamo, it is important to show they contain minerals with a special property known as ferromagnetism that allows them to record and retain records of the ancient magnetic field. Here, we present evidence the samples contain iron oxide minerals, many of which are known to be ferromagnetic. As such, we expect that future laboratory studies of these samples following their return to Earth will provide powerful constraints on the history of Mars's magnetic field. Key Points: Iron oxides with titanium and chromium components are present in lithologies sampled by the Perseverance rover on MarsThese iron oxides may contain magnetizations from ancient Martian magnetic fieldsReturned samples of these lithologies will constrain the history and characteristics of the Martian dynamo [ABSTRACT FROM AUTHOR]

Abstract: On Earth, carbonate minerals are widely used as recorders of the geological environments in which they formed. Here, we present a method designed to retrieve the crystal chemistry of Fe‐Mg carbonate minerals using infrared remote sensing or Raman spectroscopy. We analyzed a suite of well‐characterized Fe‐Mg carbonate minerals for which Raman spectra were obtained in two different laboratories, and IR spectra were measured in reflectance and transmission from the visible range to 25‐μm. We built calibration lines for the dependence of fundamental and harmonic vibrational modes position to the Mg# (defined as Mg# = 100 × Mg/(Mg + Fe + Ca + Mn)). These calibrations should enable retrieval of Mg# based on spectroscopic observations with a typical accuracy of 10. We discuss the framework of applicability of these calibrations and apply them to a typical CRISM spectrum of carbonates from the Nilli Fossae region of Mars. Key Points: Fundamental FeMg carbonate mode position have a linear dependence to Mg# for Fe‐Mg carbonate mineralHarmonic bands at 2.3 and 2.5 also have a linear dependence of their position with Mg# for Fe‐Mg carbonate mineralsWe present calibration curves of Mg# versus fundamental and harmonic vibration position than can be used to retrieve crystal chemistry [ABSTRACT FROM AUTHOR]

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 that indicate multiple episodes of aqueous alteration. In this work, we extend the analyses of hydration to targets in the Jezero western fan delta, using data from the SHERLOC (Scanning Habitable Environments with Raman and Luminescence for Organics and Chemicals) Raman spectrometer. Spectral features, for example, sulfate and hydration peak positions and shapes, vary within, and across the crater floor and western fan. The proportion of targets with hydration associated with sulfates was approximately equal in the crater floor and the western fan. All hydrated targets in the crater floor and upper fan showed bimodal hydration peaks at ∼3,200 and ∼3,400 cm−1. The sulfate symmetric stretch at ∼1,000 cm−1 coupled with a hydration peak at ∼3,400 cm−1 indicate that MgSO4·nH2O (2 < n ≤ 5) is a likely hydration carrier phase in all units, perhaps paired with low-hydration (n ≤ 1) amorphous Mg-sulfates, indicated by the ∼3,200 cm−1 peak. Low-hydration MgSO4·nH2O (n = 1–2) are more prevalent in the fan, and hydrated targets in the fan front only had one peak at ∼3,400 cm−1. While anhydrite co-occurs with hydrated Mg-sulfates in the crater floor and fan front, hydrated Ca-sulfates are observed instead at the top of the upper fan. Collectively, the data imply aqueous deposition of sediments with formation of salts from high ionic strength fluids and subsequent aridity to preserve the observed hydration states., We thank the SHERLOC and Mars 2020 science and engineering teams for the data that enabled this study.

Abstract: This 1:30,000 scale geological map describes Oxia Planum, Mars, the landing site for the ExoMars Rosalind Franklin rover mission. The map represents our current understanding of bedrock units and their relationships prior to Rosalind Franklin’s exploration of this location. The map details 15 bedrock units organised into 6 groups and 7 textural and surficial units. The bedrock units were identified using visible and near-infrared remote sensing datasets. The objectives of this map are (i) to identify where the most astrobiologically relevant rocks are likely to be found, (ii) to show where hypotheses about their geological context (within Oxia Planum and in the wider geological history of Mars) can be tested, (iii) to inform both the long-term (hundreds of metres to ∼1 km) and the short-term (tens of metres) activity planning for rover exploration, and (iv) to allow the samples analysed by the rover to be interpreted within their regional geological context.

Abstract: Planetary exploration relies considerably on mineral characterization to advance our understanding of the solar system, the planets and their evolution. Thus, we must understand past and present processes that can alter materials exposed on the surface, affecting space mission data. Here, we analyze the first dataset monitoring the evolution of a known mineral target in situ on the Martian surface, brought there as a SuperCam calibration target onboard the Perseverance rover. We used Raman spectroscopy to monitor the crystalline state of a synthetic apatite sample over the first 950 Martian days (sols) of the Mars2020 mission. We note significant variations in the Raman spectra acquired on this target, specifically a decrease in the relative contribution of the Raman signal to the total signal. These observations are consistent with the results of a UV-irradiation test performed in the laboratory under conditions mimicking ambient Martian conditions. We conclude that the observed evolution reflects an alteration of the material, specifically the creation of electronic defects, due to its exposure to the Martian environment and, in particular, UV irradiation. This ongoing process of alteration of the Martian surface needs to be taken into account for mineralogical space mission data analysis.

Abstract: The Mars 2020 Perseverance rover landed in Jezero crater on 18 February 2021. After a 100-sol period of commissioning and the Ingenuity Helicopter technology demonstration, Perseverance began its first science campaign to explore the enigmatic Jezero crater floor, whose igneous or sedimentary origins have been much debated in the scientific community. This paper describes the campaign plan developed to explore the crater floor's Máaz and Séítah formations and summarizes the results of the campaign between sols 100–379. By the end of the campaign, Perseverance had traversed more than 5 km, created seven abrasion patches, and sealed nine samples and a witness tube. Analysis of remote and proximity science observations show that the Máaz and Séítah formations are igneous in origin and composed of five and two geologic members, respectively. The Séítah formation represents the olivine-rich cumulate formed from differentiation of a slowly cooling melt or magma body, and the Máaz formation likely represents a separate series of lava flows emplaced after Séítah. The Máaz and Séítah rocks also preserve evidence of multiple episodes of aqueous alteration in secondary minerals like carbonate, Fe/Mg phyllosilicates, sulfates, and perchlorate, and surficial coatings. Post-emplacement processes tilted the rocks near the Máaz-Séítah contact and substantial erosion modified the crater floor rocks to their present-day expressions. Results from this crater floor campaign, including those obtained upon return of the collected samples, will help to build the geologic history of events that occurred in Jezero crater and provide time constraints on the formation of the Jezero delta., The Mars 2020 Perseverance rover landed in Jezero crater on 18 February 2021.

Abstract: The first samples collected by the Perseverance rover on the Mars 2020 mission were from the Maaz formation, a lava plain that covers most of the floor of Jezero crater. Laboratory analysis of these samples back on Earth would provide important constraints on the petrologic history, aqueous processes, and timing of key events in Jezero crater. However, interpreting these samples requires a detailed understanding of the emplacement and modification history of the Maaz formation. Here we synthesize rover and orbital remote sensing data to link outcrop-scale interpretations to the broader history of the crater, including Mastcam-Z mosaics and multispectral images, SuperCam chemistry and reflectance point spectra, RIMFAX ground penetrating radar, and orbital hyperspectral reflectance and high-resolution images. We show that the Maaz formation is composed of a series of distinct members corresponding to basaltic to basaltic-andesite lava flows. The members exhibit variable spectral signatures dominated by high-Ca pyroxene, Fe-bearing feldspar, and hematite, which can be tied directly to igneous grains and altered matrix in abrasion patches. Spectral variations correlate with morphological variations, from recessive layers that produce a regolith lag in lower Maaz, to weathered polygonally fractured paleosurfaces and crater-retaining massive blocky hummocks in upper Maaz. The Maaz members were likely separated by one or more extended periods of time, and were subjected to variable erosion, burial, exhumation, weathering, and tectonic modification. The two unique samples from the Maaz formation are representative of this diversity, and together will provide an important geochronological framework for the history of Jezero crater.

Abstract: International audience; The Perseverance rover landed on the floor of Jezero crater in February 2021. The initial set of images taken from the landing site of the residual butte Kodiak showed a deltaic architecture consistent with a paleolake, but at a level ~100 m lower than expected, suggestive of a closed lake system. After spending ~1 year studying the crater floor, the rover reached the front of the deltaic fan in April 2022. Here, we report observations of the facies, structure and composition of these sedimentary deposits using the SuperCam instrument. SuperCam can take images for texture analysis with the Remote Micro-Imager (RMI), visible and infrared reflectance (VISIR) spectra as well as Raman spectra for mineralogical analysis, and data from laser induced breakdown spectroscopy (LIBS) for chemical analysis. The rover investigated the basal strata of the delta along two traverses at the SE of the delta front. The transition between the crater floor and the delta is not well determined due to regolith and strongly degraded outcrops, and is currently under assessment. The ~20 m thick basal layers that are well-visible on orbital data consist of fine-grained sandstones and siltstones deposited in sub-horizontal planar beds with millimeter thick laminations. These deposits display a substantial alteration highlighted by the detection of both sulfates and phyllosilicates, with exception of local boulders of igneous texture lacking alteration. Texture and composition are both consistent with a quiet regime of deposition such as in lake deposits or distal delta slopes. These beds are considered of topmost importance for sample return and were cored in two locations. Pebbly sandstones and conglomerates with pebbles limited to a few centimeters are observed immediately above these strata. The texture is matrix-supported suggesting an emplacement through gravity sliding or turbidity flows below water rather than fluvial deposition. The composition is more variable than in underlying finer-grained beds and includes local carbonate detections. Uppermost deposits have not been reached by the rover yet, but have been analyzed remotely by RMI images, and VISIR for some of them. They consist of cross-bedded sandstones and conglomerates in all locations of the delta front. The diversity in texture of these deposits suggests a variability in depositional regimes including high-energy floods, either during the lacustrine phase, or subsequently. Boulders present within these layers are rounded suggesting a substantial abrasion by fluvial transport. These boulders are also interesting targets for sampling distant crustal rocks. The top of the delta will be analyzed and sampled along the traverse of the rover in 2023.

Abstract: International audience; On ~sol 370 of the Perseverance rover mission, the Mars 2020 Science Team completed its investigation of igneous units of the Jezero crater floor [1] and directed Perseverance to drive towards the topographic scarp that marks the interface between the crater floor and Jezero’s western delta. The “Delta Front Campaign” consisted of close-up investigation and sampling of lithologies located there.Here, we report on the major findings relevant to the provenance and diagenetic history of these lithologies deduced from measurements made by the Planetary Instrument for X-ray Lithochemistry (PIXL), a micro-focus X-ray fluorescence (XRF) microscope [2]. Data were collected from two sections at Cape Nukshak and Hawksbill Gap; outcrop and member names are from [3]. Lithologies are described here in order from base to top of each section.

Abstract: International audience; Since the end of April 2022, the Perseverance rover has embarked on the Delta Campaignwith the objective to explore the sedimentary delta of Jezero Crater and characterize its stratigraphyand mineral composition. Among the instruments aboard the Rover, SuperCam [1, 2] plays a keyrole in this study thanks to its remote measurement capabilities (spectroscopy and imaging), in particularthe near-infrared reflectance spectroscopy performed by the IRS instrument [3]. This instrument analyzeslight reflected from rocks and soils in the 1.3 – 2.6 μm spectral range and in a field of view of 1.15 mrad,corresponding to an area of about 3.5 mm at 3 m distance. The IRS is thus sensitive to the spectral signaturesof primary and aqueous alteration minerals, enabling the analysis of the compositional diversity of rocks and thus to the study of their formation conditions. Here we summarize a modeling approach of the IRS data to examine diagnostic absorption features.

Abstract: International audience; During the first scientific campaign, Perseverance explored the Jezero crater floor and found two main igneous formations: the basaltic Máaz unit, and Séítah, consisting of an olivine-rich cumulate. Then the rover did a rapid traverse towards the second campaign region, Jezero’s delta. Just before reaching the lowest part of the delta, Perseverance encountered the Séítah formation again, with some variability in the degree of alteration. Here, we use the data obtained by the SuperCam instrument to document the structure and texture of rocks at the transition between Séítah and the delta front, its geochemistry and its primary and secondary mineralogy. Then, we discuss the simi-larities/differences between these rocks and discuss a geological scenario to account for these observations.

Abstract: International audience; In February 2021, the Perseverance rover landed in Jezero crater, Mars. The crater floor was found to be composed of lava flows and cumulate rocks [1-5]. These magmatic rocks appear to have undergone some limited aqueous alteration; however, it is not clear whether this alteration is related to the lacustrine phase of the crater [1,3,6,7].After completing its exploration of the crater floor, Perseverance reached the foot of the Jezero western fan in late April 2022 (sol ~422). Long-distance images acquired earlier in the mission had already confirmed the deltaic nature of the fan [8], which had long been suspected from orbital observations [9,10]. Between April and December 2022, Perseverance investigated the basal layers of the delta at two locations named Hawksbill Gap and Cape Nukshak, which are ~400 m apart [11]. Here, we present an overview of the geo-chemistry and mineralogy of the delta rocks as observed by SuperCam, and show that these rocks record a diver-sity of past aqueous alteration environments.

Abstract: International audience; The Perseverance rover landed in the ancient lakebed of Jezero crater, Mars on February 2021. Here we assess the mineralogy of the rocks, regolith, and dust measured during the first year of the mission on the crater floor, using the visible and near-infrared spectrometer of SuperCam onboard the Perseverance rover. Most of the minerals detected from orbit are present in the bedrock, with olivine-bearing rocks at the bottom of the stratigraphy and high-Ca pyroxene-bearing rocks at the top. This is distinct from the overall low-Ca pyroxene-bearing composition of the watershed of Jezero, and points towards an igneous origin. Alteration mineral phases were detected in most of the rocks analyzed in low proportions, suggesting that aqueous alteration of the crater floor has been spatially widespread, but limited in intensity and/or time. The diverse aqueous mineralogy suggests that the aqueous alteration history of the crater floor consists of at least two stages, to form phyllosilicates and oxyhydroxides, and later sulfates. We interpret their formation in a lake or under deeper serpentinization conditions, and in an evaporative environment, respectively. Spectral similarities of dust with some rock coatings suggest widespread past processes of dust induration under liquid water activity late in the history of Jezero. Analysis of the regolith revealed some local inputs from the surrounding rocks. Relevant to the Mars Sample Return mission, the spectral features exhibited by the rocks sampled on the crater floor are representative of the diversity of spectra measured on the geological units investigated by the rover.

Abstract: International audience; The Perseverance rover (Mars 2020 mission, NASA) is exploring the mineral diversity of the paleolake within Jezero crater and is searching for potential biosignatures and past habitability. Amongst its science payload, the SuperCam instrument plays a central role in the Mars habitability investigation by providing rapid, synergistic, fine-scale mineralogy, chemistry, and color imaging [1, 2]. In particular, it carries the first near-infrared spectrometer, IRS, to be operated on the Martian surface. IRS is a miniaturized point spectrometer (1.15 mrad field of view) located in the SuperCam’s mast unit. Its spectral range (1.3 – 2.6 µm range) covers major silicate, salts and hydrated mineral absorption features [3].Mineral identifications are performed by analyzing the position and shape of diagnostic absorption bands. The recent results on the instrument’s radiometric calibration [4] enabled the identification of a 2.50 - 2.53 µm absorption feature attributable to carbonates. Carbonates also exhibit a 2.3 µm band similar to the 2.30 - 2.33 µm Fe/Mg-OH band of several phyllosilicates. Thus, this 2.5 µm feature is key to decorrelate the presence of phyllosilicates and carbonates. In the Crater Floor unit, it has been identified only in the Séitah formation, with the support of LIBS investigation [5], and many occurrences have been detected in the Delta.The study of the band depth ratio between the 2.3 and 2.5 µm bands, in terms of detection quality (signal to noise ratio, Fig. 1), shows that positive carbonates detections are consistent with phyllosilicate-carbonate mixtures with a low Mg/Fe-carbonate content. In the Crater Floor, this low carbonate content in presence of phyllosilicates and silicates points towards an alteration of the mafic phase with a CO2-rich fluid. Work is in progress to better understand deconvolution of carbonates from phyllosilicates.

Abstract: International audience; Jezero crater was chosen for exploration and sample collection by Perseverance due to its history as a lake with river deltas, its diverse mineralogy, including carbonates observed from orbit, and as a potential site to calibrate crater counting ages with radiometric dates of samples to be returned to Earth. This presentation focuses on the results of SuperCam, which uses LIBS for remote elemental chemistry, VISIR and remote Raman spectroscopy for mineral compositions and alteration, includes a microphone, and performs high-resolution imaging for textures and morphology. In the first year after landing, SuperCam and other instruments were used to explore Jezero’s floor. We found that all of the floor units are igneous, with lava flows comprising the upper units as part of the Máaz formation, while the lower formation, Séítah, is an olivine cumulate, produced by gravitational settling of olivine crystals in a large melt body. Artuby ridge, just outside the SW portion of Séítah and stratigraphically just above it, contains up to 60% pyroxene. The upper portions of the Máaz formation are more enriched in plagioclase, with the uppermost Ch’al member having the most evolved composition, along with the Content member, pitted rocks directly overlying the main cumulate portion of Séítah. After exploring the floor, Perseverance drove to the delta formation and began a walk-about style of observations starting at Enchanted Lake, just below an arm of the delta formation, and then moving into Hawksbill Gap, climbing 18 m in elevation between Devil’s Tanyard, Sunset Hill, and Hogwallow flats. Delta compositions initially displayed higher phyllosilicate contents, identified by absorptions at 1.4, 1.9, and 2.3 µm, and by higher LIBS H peak areas. Farther up, compositions changed to sulfur-bearing in lower locations within the continuous fine-grained light-toned strata (e.g., Pignut Mountain, Sol 463) and carbonate-rich in upper strata. Veins were observed, consisting of Mg-Fe carbonate (Elder Ridge, Sol 459) and anhydrite (Reid’s Gap, Sol 466). The sulfates suggest precipitation of these salts at a later stage, as the lake was evaporating. Carbonates and sulfates in veins in different locations indicate that groundwater was active in the lithified sediments and had significantly different chemistry at different intervals.

Abstract: The Mars 2020 rover landed at Jezero crater on February 18, 2021. Since then, the rover has traveled around the “Séítah” region and has collected data from the Mastcam-Z, Supercam, PIXL and SHERLOC instruments that has led to insights into the formation of the olivine-clay-carbonate bearing rocks that were identified from orbit. Here we discuss three questions: 1) What have we learned about the olivine-clay- carbonate unit? 2) What terrestrial analogs exist for the unit? 3) Why do the rocks have a thinly layered morphology? We shall briefly mention instrumental measurements which provide important information regarding the olivine bearing rock at Seitah.

Abstract: Before Perseverance, Jezero crater's floor was variably hypothesized to have a lacustrine, lava, volcanic airfall, or aeolian origin. SuperCam observations in the first 286 Mars days on Mars revealed a volcanic and intrusive terrain with compositional and density stratification. The dominant lithology along the traverse is basaltic, with plagioclase enrichment in stratigraphically higher locations. Stratigraphically lower, layered rocks are richer in normative pyroxene. The lowest observed unit has the highest inferred density and is olivine-rich with coarse (1.5 millimeters) euhedral, relatively unweathered grains, suggesting a cumulate origin. This is the first martian cumulate and shows similarities to martian meteorites, which also express olivine disequilibrium. Alteration materials including carbonates, sulfates, perchlorates, hydrated silicates, and iron oxides are pervasive but low in abundance, suggesting relatively brief lacustrine conditions. Orbital observations link the Jezero floor lithology to the broader Nili-Syrtis region, suggesting that density-driven compositional stratification is a regional characteristic.

Abstract: International audience; The Perseverance rover (Mars 2020 mission, NASA) landed in the ancient lakebed of Jezero crater, Mars on February 2021. The payload includes the SuperCam instrument, which combines various remote-sensing techniques to investigate elemental and mineralogical composition. In particular, the near-infrared spectrometer of SuperCam is a novel instrument on the Martian surface. The spectra, together with data from additional visible spectrometers, cover the 0.390.85 m (VIS) and 1.32.6 m (IR) ranges, allowing the identification of a wide variety of minerals. Here, we present the spectral diversity in the VISIR of rocks and soils in the vicinity of the rovers traverse. As of sol 130, most of the rocks analyzed so far are dark-toned rocks in the crater floor (Cf-fr unit) with variable dust cover. Some variability in reflectance levels and absorption bands is observed within and among the rocks, but overall, they share similar spectral characteristics. In particular, most rocks exhibit an absorption near 1.9 m (indicating the presence of water). This band is usually observed weakly or is absent in local regolith but is detected with a depth up to ~20% in the rocks, indicating probably several wt.% of bound water. While mixing of different phases occurs in the few mm of the field of view of the spectrometer, the following candidates were identified: dust, an oxy-hydroxide (e.g., ferrihydrite), an iron-rich phyllosilicate (e.g., nontronite or hisingerite) and an AlOH-bearing phase. Contrary to what have been inferred from the orbit, no unequivocal mafic mineral signature has yet been identified in a rock target in the VISIR implying low mafic minerals content or small associated grain size. However, the soils exhibit a signature of olivine mixed with pyroxene (intermediate Ca content). Portions of sand ripples are strongly dominated by the olivine signature. The detection of widespread hydration features supports that some pervasive water-rock interactions occurred in the past near the Perseverance landing site. From CRISM orbital data, it is likely that the rover will be driving through areas exhibiting progressively increasing hydration throughout its traverse: future measurements on these potentially more hydrated and diverse rocks are expected to bring new insights into the past environment at Jezero crater.

Abstract: International audience; On February 18, 2021 NASAs Perseverance rover landed in Jezero Crater where the floor consists of various rock lithologies and abundant regolith. Using the rovers imagery and the LIBS and VISIR spectroscopies from SuperCam, we focus on the chemistry and mineralogy of coarse-grained regolith. Such regolith has been observed all along the rover traverse since the landing: it is widespread either on flat surfaces/rocks or in aeolian ripples. This coarse regolith is composed of rounded granules rather homogeneous in size (~1-2 mm), shape (nearly isotropic) and color. Some VISIR spectra are highly consistent with the presence of olivine in the regolith. No hydration band is detected, and no H is detected by LIBS, suggesting that this olivine is rather pristine. SuperCam LIBS has a laser spot size of 300 mm and is operated by performing rasters of up to 10 sampling points, each accumulating up to 50 laser shots. Combining high-resolution RMI images with microphone recordings during the laser shots, we can assess whether the LIBS laser sampled dust/fine sand or granules during the shot series, and if the laser significantly ablates a granule. Careful analysis of the LIBS spectra and derived chemical compositions, including comparison with data from calibration targets and shot to shot variability, reveal the presence at the LIBS spot size of (i) olivine only, (ii) olivine and andesine mixtures, and (iii) other assemblages including the former and/or other minerals such as pyroxenes. Most olivine grains are Fo# 60-75, but locally some grains may be lower Fo#; they all exhibit low content of Cr and Mn, Ni is below detection limit. Interestingly, this coarse regolith displays a different chemistry and mineralogy compared to the surrounding rocks raising questions about its provenance. The rover is currently making its way toward the adjacent Seitah unit which is a possible source as it may contain olivine based on orbital data. There are also some differences in composition between these granules and the finer fractions of the regolith. All these data will be compared to orbital data and observations by Curiosity on similar coarse-grained regolith at Gale crater. They will also be discussed in light of knowledge from Martian meteorites to place constraints on the formation of olivine and magmatic processes on Mars.
