Summary: The observed enrichment of sulfur on the surface of Mercury is proposed to be the result of reactions between silicate and reduced volcanic gases. Experimental and spectroscopic evidence supports this hypothesis, and future missions will further investigate and provide constraints on the origin of sulfur enrichment on Mercury's surface.

Summary: The research discusses the importance of using the ExoMars Raman Laser Spectrometer (RLS) to identify reduced carbon on Mars and analyze its impact on the habitability of the planet. Spectral data obtained confirm that the RLS instrument can accurately detect differently thermally processed carbon materials and demonstrate that impact shock can increase the molecular disorder of carbon, potentially making it more biologically accessible.

Summary: In this study, sediment samples from sulfur-rich environments in Iceland and Canada were analyzed for quadruple sulfur isotope values, revealing different microbial sulfur cycling processes between the sites. The results suggest the potential for quadruple sulfur isotope values to serve as biosignatures for life in sulfur-rich Martian environments. The contrasting physical and chemical characteristics of the sites support different microbial sulfur cycling processes, with implications for targeting sites for future missions to Mars.

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: This study presents methods for ion irradiation experiments on mineral powder pellets for rocky planetary bodies. The experiments showed changes in thermal IR reflectance properties of the pellets after irradiation, with surface abrasion found to remove the sputter effect. Additionally, experiments in a quartz crystal microbalance catcher setup demonstrated the study of irradiation induced sputtering and surface alteration under laboratory conditions.

Summary: This study used the middle infrared (MIR) channel of the atmospheric chemistry suite (ACS) instrument to monitor the properties of Martian water ice clouds over two Martian years. The results showed variations in cloud altitude between seasons and regions, and the comparison with a Mars planetary climate model revealed overall agreement in cloud altitude, although the model predicted lower altitudes for the top of the clouds.

Summary: Recent advancements in infrared frequency combs have made it easier to record coherent two-dimensional infrared spectra of gas-phase molecules with rotational resolution. By deriving new polarization conditions specific to freely rotating molecules, certain parts of the 2DIR spectra can be suppressed, resulting in clearer and more comprehensible spectra. This method can be applied to study complex gas mixtures of polyatomic molecules.

Summary: Classic dynamic high-pressure experiments on porous San Carlos olivine powder showed that different shock stages modify corresponding reflectance mid-infrared spectra, with one RB of olivine at 980 cm(-1) serving as a proxy for its presence. Additionally, a peak at around 1060 cm(-1) displayed intensity changes possibly related to shock exposure or grain orientation effects, and the presence of a weak band around 1100 cm(-1) influenced the position of the CF when averaging spectral data of olivine.

Summary: This study analyzed plagioclase feldspar samples to determine their chemical composition and degree of Al,Si order using mid-infrared reflection spectra, electron microprobe analyzer, and powder X-ray diffraction methods. The position of Christiansen feature (CF) and autocorrelation were used to interpret the infrared spectra and determine the Al,Si order of samples. The results are helpful for interpreting data from the MERTIS experiment and distinguishing between different effects in plagioclase samples.

Summary: Temperature measurements on the lunar surface at centimeter scales in short-wavelength infrared were observed in situ by the Chang'E-4 rover, providing additional information to existing large-scale data. Surface roughness at subresolution scales was found to affect the observed thermal radiances and derived temperatures, highlighting the importance of considering this factor when determining the thermal properties of lunar regolith.

Summary: Planetesimals in the early stage of planetary formation are thought to have been porous aggregates of dust, with boulders on the surface of asteroid (162173) Ryugu found to have an average porosity of 30-50%, higher than meteorites but lower than cometary nuclei. High-resolution thermal and optical imaging revealed boulders with over 70% porosity at the bottom of small craters on Ryugu, indicating they may be the least processed material on the asteroid and remnants of porous planetesimals.

Summary: The last thirty years have shown that small bodies formed in the outer Solar System are a major reservoir that is vastly undersampled in current extra-terrestrial materials. Studying these objects could lead to significant breakthroughs in planetary science by providing insights into the least processed materials closest to the origin of the Solar System. Sample return missions are necessary to achieve this goal, with proposals already submitted to ESA for future missions in the 2035-2050 time frame.

Summary: Candidate closed and open-basin lakes on Mars show exposed sediments of possible lacustrine origin, with recent CRISM observations confirming the presence of water alteration minerals in some structures. The location and characteristics of these altered minerals suggest a lacustrine origin, with evidence of transported minerals within lake deposits rather than in situ alteration. This discovery provides insights into the role of liquid water on Mars.
