Summary: Understanding the genesis of Martian soils is crucial for understanding the planet's hydrogeologic history. Analyzing the composition and formation of the soils can provide insights into the ancient environmental conditions. This study used the ChemCam instrument to investigate the nature and origin of hydrated amorphous phases in Martian soils, and found clues for the presence of sulfates. The results suggest that sulfates are the main carriers of soil hydration and may explain the hydrogen and sulfur measurements from orbit.

Summary: This study provides measurements to support the previous report of continuous wave fiber lasing in Ce3+-doped selenide chalcogenide SIF. In-band pumping of Ce3+ in different geometries results in mid-infrared photoluminescence ranging from 3.40-5.80 μm. The emission and absorption spectra at room temperature facilitate the interpretation of excited states and indicate the presence of occupied Stark levels in the ground state. The decay and rise time of the photoluminescence are determined for ground glass at 4.60 μm.

Summary: Mud volcanism has been proposed as a formation mechanism for certain landforms on Mars, but data from CRISM has not been fully utilized to study these features. While specific minerals like phyllosilicates, carbonates, or sulfates were not confidently identified, hydrated glass of volcanic origin and high-Ca pyroxene were observed in Valles Marineris. Nanophase ferric oxide signatures were consistent on a global scale in CRISM visible data from mud volcano features.

Summary: While single-phase salts on Mars have received much attention, little research has been done on mixed evaporative assemblages. This experimental study analyzes multicomponent brines to understand their spectral signatures and identifies the predominance of certain salts. The results suggest that regions with identified Mg-sulfate on Mars may have limited amounts present and other sulfates or halides may be undetectable.

Summary: The study investigated the accuracy of on-site visible-near IR spectroscopy predictions of iodine number and fatty acid composition of raw ham subcutaneous fat, and evaluated their effectiveness as indicator traits of ham fat quality in a pig breeding program. Accuracy was relatively poor, but R-2 in external validation was > 0.7 for iodine number and certain fatty acids. On-site visible-IR predictions are accurate enough to support the use of this technique for large-scale phenotyping of raw ham fat quality and may be implemented as indicator traits in breeding programs.

Summary: Recent studies using mass spectrometry and IR photodissociation have provided evidence for the existence of octa-coordinated ionic lanthanide-carbonyl complexes under extreme gaseous conditions. Previous literature on cryogenic studies of neutral Ln(CO)(x) species suggested a maximum coordination number of hexa-coordinated Ln(CO)(6) molecules. This study aims to clarify the controversy through matrix isolation spectroscopy and DFT calculations, confirming the preference for octa-coordinated Ln(CO)(8) complexes in cryogenic neat CO matrices.

Summary: In this study, a combined experimental and computational approach was used to investigate the Rozenite mineral component of sulfate deposits on Mars. The structure and properties of the mineral were analyzed using neutron powder diffraction, synchrotron X-ray data, and Raman spectra. It was found that there are no phase transitions between 21 and 290 K, contrary to previous studies. The complete crystal structure and thermal expansion behavior of Rozenite were determined, and the combination of Raman spectroscopy and X-ray diffraction with first-principles calculations yielded accurate reference Raman spectra.

Summary: Glen Torridon is a topographic trough on Mars with relatively strong spectral signatures of clay minerals. The Curiosity rover explored the area for over 700 Martian days to understand the geologic context of clay mineral formation and determine the intensity of aqueous alteration. Analysis of the bedrock's major-element geochemistry reveals distinct chemical compositions and mineralogical interpretations. Overall, the alteration in Glen Torridon shows elevated Chemical Index of Alteration values, suggesting the formation of clay minerals through open-system weathering.

Summary: We conducted a combined analysis of crater floor rocks in Jezero crater using geomorphologic, multispectral, and geochemical data obtained by the Mast Camera Zoom and SuperCam instruments onboard the NASA Mars 2020 Perseverance rover. Our study allows us to interpret the origins of rocks exposed along the Artuby ridge, which are predominantly lava flows with some layers formed by weathering, volcanic ash deposition, or wind-borne sediment deposition. These findings provide crucial geological context for the Maaz formation samples that will be returned to Earth and highlight the diversity and complexity of geologic processes on Mars.

Summary: The Perseverance rover examined the mineralogy of the rocks, regolith, and dust in the Jezero crater on Mars. It found that the bedrock contains olivine-bearing rocks at the bottom and high-Ca pyroxene-bearing rocks at the top, suggesting an igneous origin. Aqueous alteration was detected in most of the rocks, indicating widespread but limited alteration of the crater floor. The diverse mineralogy suggests at least two stages of aqueous alteration, forming phyllosilicates and oxyhydroxides, and later sulfates.

Summary: A study conducted by the Perseverance rover on the regolith of Jezero crater floor units identified three types: fine-grained, coarse-grained, and mixed-type. The characteristics of these regolith types, such as texture, particle size, and composition, were determined using various instruments. Fine-grained regolith was found surrounding bedrock and boulders, coarse-grained regolith consisted of well-sorted gray grains, and mixed-type regolith included both fine and coarse-grained components. The findings of this study provide valuable insights for understanding regolith formation within Jezero crater.

Summary: This study analyzed data from the Cassini spacecraft's Visual and Infrared Mapping Spectrometer (VIMS) to study the surface composition and landscape formation of the Selk crater region on Titan. The results suggest that the mountainous terrains in the area are likely dominated by fine grains of organic sediment, which may be transported to the lowlands by rivers and deposited as sand particles. These findings are important for the preparation of the Dragonfly mission and future exploration of Titan's surface composition and geology.
