- Abstract
We have developed a down-the-hole (DTH) rotary-percussive drill prototype that could operate on compressed Mars atmospheric CO2 gas with a wireline drilling approach. This technology addresses a need for more aggressive sampling and drilling techniques, for both scientific purposes and to obtain In-Situ Resource Utilization (ISRU) resources for future NASA missions and human crew support. Using a spool of lightweight, high-pressure capillary, a DTH drill assembly would be moved in and out of the hole that could be a kilometer or more in depth. The CO2 drill is designed so that Mars atmospheric CO2 could be collected, compressed, and supplied down the hole and routed through microducts, valves, and reservoirs for the purpose of controlling miniature mechanical actuation in the assembly. By using compressed CO2, the drill system avoids the need for heavy electrical cabling and actuator systems or a liquid media for carrying away particulates as is typically used in terrestrial drilling systems. Instead, the liquid CO2 that powers the drill expands to a gas and could be channeled around the drill housing to carry cuttings to be collected in a bailing bucket. Where terrestrial systems often use drill depth vs time as a metric, a Mars drilling system would need to be extremely low mass, but would have no need to perform under tight schedules. In this paper, we will document our trade studies, progression for the design of microduct logic verified through multiple generations of prototypes, and provide predictive performance data on energy consumption, hole depth, and drill time.

- 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.

[SDU]Sciences of the Universe [physics] - 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
Ancient biosignatures are key to understanding the emergence and evolution of life in its planetary context. Microbes thrived on Earth from at least the early Archean to the present, and similar organisms may have emerged on a warmer, wetter Mars in the past, as well. However, fossil evidence of ancient microbes is often difficult to identify and interpret. Early diagenetic chert preserves numerous examples of microbial biosignatures from the Proterozoic and Archean eons. Despite their presence in the rock record, though, the mechanism behind this biosignature preservation and the biological and abiotic factors that contributed to the precipitation of chert are not well understood. Here, we address these uncertainties through fossilization experiments and analyses of Proterozoic biosignatures and the minerals that preserved them. Fossilization experiments reveal that exopolymeric substances (EPS) produced by some cyanobacteria can promote the precipitation of amorphous silica by using magnesium as a cation bridge. Scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDS) maps of biosignatures in Proterozoic chert reveal that the organic matter is commonly associated with magnesium-, calcium-, and aluminum- rich phases. In contrast, chert that does not contain organic matter lacks these cation associations. These combined results suggest that interactions among organic matter and major element cations in seawater may have promoted the preservation of organic matter by chert in marine environments during the Proterozoic. Our findings provide a window into interactions between microbes and their environments on the early Earth and the microbial contribution to geochemical cycles and chert formation. By analyzing these biosignatures and constraining the processes that led to their formation on Earth, we may be better equipped to identify and interpret potential biosignatures in Jezero crater, the landing site of the Mars2020 rov

Dynamic aperture factor analysis/target transformation (DAFA/TT) for Mg-serpentine and Mg-carbonate mapping on Mars with CRISM near-infrared data. Icarus, 355, (2021): 114168, https://doi.org/10.1016/j.icarus.2020.114168., Serpentine and carbonate are products of serpentinization and carbonation processes on Earth, Mars, and other celestial bodies. Their presence implies that localized habitable environments may have existed on ancient Mars. Factor Analysis and Target Transformation (FATT) techniques have been applied to hyperspectral data from the Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) to identify possible serpentine and Mg-carbonate-bearing outcrops. FATT techniques are capable of suggesting the presence of individual spectral signals in complex spectral mixtures. Applications of FATT techniques to CRISM data thus far only evaluate whether an entire analyzed image (≈ 3 × 105 pixels) may contain spectral information consistent with a specific mineral of interest. The spatial distribution of spectral signal from the possible mineral is not determined, making it difficult to validate a reported detection and also to understand the geologic context of any purported detections. We developed a method called Dynamic Aperture Factor Analysis/Target Transformation (DAFA/TT) to highlight the locations in a CRISM observation (or any similar laboratory or remotely acquired data set) most likely to contain spectra of specific minerals of interest. DAFA/TT determines the locations of possible target mineral spectral signals within hyperspectral images by performing FATT in small moving windows with different geometries, and only accepting pixels with positive detections in all cluster geometries as possible detections. DAFA/TT was applied to a hyperspectral image of a serpentinite from Oman for validation testing in a simplified laboratory setting. The mineral distribution determined by DAFA/TT application to the laboratory hyperspectral image was consistent with Raman analysis of the serpentinite sample. DAFA/TT also successfully mapped the spatial distribution of Mg-serpentine and Mg-carbonate previously detected in CRISM data using band parameter mapping and extraction of, This work was supported by the National Natural Science Foundation of China (grant no. 41671360, 41525016, 41902318).

- 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.
