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: This chapter reviews the way the six key questions about planetary systems, from their origins to the way they work and their habitability, identified in Chapter 1 (Blanc et al., 2021), can be addressed by means of solar system exploration, and how one can find partial answers to these six questions by flying to the different provinces to the solar system: terrestrial planets, giant planets, small bodies, and up to its interface with the local interstellar medium. It derives from this analysis a synthetic description of the most important space observations to be performed at the different solar system objects by future planetary exploration missions. These “observation requirements” illustrate the diversity of measurement techniques to be used as well as the diversity of destinations where these observations must be made. They constitute the base for the identification of the future planetary missions we need to fly by 2061, which are described in Chapter 4.

Abstract: International audience; The $Perseverance$ rover, Mars 2020 mission, landed on the surface of the Jezero Crater, on February, 18th 2021. This Martian crater is suspected to have hosted a paleolake as evidenced by the numerous detections of aqueously-altered phases and thus is a promising candidate for the search for past Martian life. The SuperCam instrument, a collaboration by a consortium of American and European laboratories, plays a leading role in this investigation thanks to its highly versatile payload providing rapid, synergistic, fine-scale mineralogy, chemistry, and color imaging. After its landing, the first measurements of Martian targets with the infrared spectrometer of SuperCam (IRS) showed new instrumental behaviors that had to be characterized and calibrated to derive unbiased science data. The IRS radiometric response has thus been calibrated using periodic observations of the Aluwhite SuperCam Calibration Target (SCCT). Parasitic effects were understood and mitigated, and the instrumental dark and noise are characterized and modeled. The reflectance calibrated data products, provided periodically on the NASA Planetary Data System, are corrected for the main instrumental features. This radiometric calibration allowed us to study the 2.5 μm absorption band which has been discovered in the Séítah unit and is associated with phyllosilicates-carbonates mixtures.

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: The ~31-km-wide Hiawatha structure, located beneath Hiawatha Glacier in northwestern Greenland, has been proposed as an impact structure that may have formed after the Pleistocene inception of the Greenland Ice Sheet. To date the structure, we conducted 40Ar/39Ar analyses on glaciofluvial sand and U-Pb analyses on zircon separated from glaciofluvial pebbles of impact melt rock, all sampled immediately downstream of Hiawatha Glacier. Unshocked zircon in the impact melt rocks dates to ~1915 million years (Ma), consistent with felsic intrusions found in local bedrock. The 40Ar/39Ar data indicate Late Paleocene resetting and shocked zircon dates to 57.99 ± 0.54 Ma, which we interpret as the impact age. Consequently, the Hiawatha impact structure far predates Pleistocene glaciation and is unrelated to either the Paleocene-Eocene Thermal Maximum or flood basalt volcanism in east Greenland. However, it was contemporaneous with the Paleocene Carbon Isotope Maximum, although the impact’s exact paleoenvironmental and climatic significance awaits further investigation.

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.

Abstract: International audience; On February 18, 2021, NASAs Mars 2020 Perseverance rover landed successfully in Jezero crater. Several geological and compositional units have previously been identified from orbital data analysis [1,2]: a dark pyroxene-bearing floor unit; an olivine-bearing unit exposed in erosional windows partially altered into phyllosilicates and carbonates [3]; a deltaic complex with possible remnants and marginal carbonate-bearing unit [1]. The SuperCam instrument contains a suite of techniques including passive spectroscopy in the 0.40-0.85 (VIS) and 1.3-2.6 microns (IR) wavelength ranges, and a camera (RMI- Remote Micro-Imager) providing high resolution context images [4]. Since the landing, SuperCam has acquired tens of observations on distant targets (from 10s of m to 20 km) with VISIR and RMI techniques. The IFOV of the RMI images ranges from ~100 microns at 10m to ~20 cm at 20 km allowing to solve objects from ~0.5 mm at 10 m to ~1m at 20 km and the VISIR FOV range from 1 cm to 20 m. Distant observations have been acquired on the western delta front, several mesas and hills, on Jezero floor unit (the unit perseverance landed on and investigated in situ), on the olivine-bearing erosional window, and on more distant targets such as the crater rim or marginal carbonate-bearing unit. The observed spectral signatures form different clusters depending on the type of target, confirming the spectral diversity of Jezero geological units. The western delta front and a residual butte informally named Kodiak are clustered together with spectral signatures in agreement with a mixture of olivine, pyroxene and hydrated phases. The spectra of the erosional window into the olivine bearing unit display the strongest red slope between 1.3 and 1.8 microns, suggesting the presence of olivine in both the exposed rocks and the surrounding soils and in addition, the rocks display a strong signature of hydrated phases. The long distance observations of the crater floor unit are in agreement with the spectral signature identified in the vicinity of the rover [5], which confirms the relevance of long distance observations to assess the geological/mineralogical context of Perseverances future traverse.

Abstract: International audience; Atmosphereless bodies of the Solar System present surface evolution under the harsh conditions of space weathering. Their regolith are exposed to thermal cycling, cosmic and solar rays irradiation, solar wind sputtering and micrometeorites bombardment and vaporization. With time these materials accumulate optically active opaque particles such as nanophase metallic iron particles on the surface or rims of dust grainsor larger iron particles. The density increase in iron particles modifies the spectral properties of the material with a lowering of the particlesalbedo, and of the absorption bands amplitude generally associated with a global reddening of the spectral slope [1, 2].Previous studies have shown that nanophase iron particles inducing weathering spectral properties will accumulate at the surface of olivine and pyroxene minerals under heating conditions simulating micrometeorite impacts [3]. The skin depth of weathered material depends on theweathering process and minerals.Laboratory simulations by heating samples under reducing conditions can recreate the conditions under which regolith may be weathered inspace with surface alteration of grains and apparition of nanophase iron on the altered depth. The effect of the changes on the grain spectralproperties depending on the experimental conditions will be further studied for applications to airless bodies in the Solar System. The sampleswill be analyzed with SEM at IRAP and their reflectance spectra acquired with the SHADOWS instrument at IPAG [12] for future comparisonswith the spectra of Phobos and Deimos.
