While techniques such as DRIFTS (Diffuse Reflectance Infrared Fourier Transform Spectroscopy), RLS (Raman laser spectrometer ExoMars simulator), and LIBS (Laser Induced Breakdown Spectroscopy onboard the Curiosity and Perseverance rovers) closely matched the mineralogical composition of the site (Figs.S11...
From this graph, it seems that during the local summer, the northern polar cap evaporates more actively; thus, the amount of water vapor in the near-surface atmosphere is also higher. This, combined with the high enough temperatures, could lead to better chances for deliquescence in the ...
The thermal conduction model we used (Bramson et al., 2017) to calculate the annual average surface temperature (162 K) considers a simplified atmosphere that parameterizes infrared and visible scattering, but not attenuation through the path length of the atmosphere, which is more important at ...
An alternative offered by those glaciation models is that, under an ancient 1 bar atmosphere, only the summit of Amphitrites Patera as well as the adjacent Barnard crater rim would have peaked above this late Noachian ice stability altitude while the remainder of the northern Malea Planum region...

Earth receives considerably less meteoroid mass (between 2900 and 7300 kg per year, excluding dust particles), which is also slowed down considerably by the atmosphere [28]. The danger of meteoroid impact persists not only for potential humans and habitats on Mars, but also for the 3D-printing...
Gale crater was a deep depression in the Mars crust (4650 m below the average elevation of Mars) at a time when the Mars atmosphere was dense enough and the climate warm enough to allow liquid water to flow on its surface. Figure 1. Color-coded topographic map of Gale crater, located ...
However, a key difference between reports is that Marlow and colleagues allowed Martian groundwaters to react with the Martian atmosphere; we keep the water–rock reaction path closed in the rock subsurface. Comparative terrestrial analog studies remain in high demand; terrestrial microbes toggle ...
The measured peak intensities were converted to weight percentages by the software and the average composition was computed. 5.3. X-ray Diffraction (XRD) The rock mineralogy of WNMS was measured through X-ray diffraction (XRD). A Bruker D8 Advance Diffractometer was used to record the X-ray ...
