Supercooling, Glass Formation, and Mineral Assemblages upon Freezing of Salty Ice Grains from Enceladus’s Ocean

The Planetary Science Journal
The analysis of micrometer-sized ice grains emitted into space by Saturn’s moon Enceladus suggests that the moon’s subsurface ocean may be habitable. However, the formation conditions of these ice grains are largely unknown.

Carbonic anhydrase traced by cadmium isotope fractionations in Archean to Holocene stromatolitic carbonates

Communications Earth & Environment
Stromatolites record interactions of the biosphere, atmosphere, and hydrosphere. The evolution of C-fixation via diverse metabolisms is linked to metal availability for enzymes such as carbonic anhydrase.

Global Lunar FeO Mapping via Wavelet–Autoencoder Feature Learning from M3 Hyperspectral Data

Mathematics
Accurate global mapping of lunar iron oxide (FeO) abundance is essential for understanding the Moon’s geological evolution and for supporting future in situ resource utilization (ISRU).

Mineralogy and noble gas isotopes of micrometeorites collected from Antarctic snow Planetary Science

Mineralogy and noble gas isotopes of micrometeorites collected from Antarctic snow Planetary Science
We have investigated seven micrometeorites (MMs) from Antarctic snow collected in 2003 and 2010 by means of electron microscopy, X-ray diffraction, micro-Raman spectroscopy, transmission electron microscopy (TEM) observation, and noble-gas isotope analysis. Isotopic ratios of He and Ne indicate that the noble gases in these MMs are mostly of solar wind
