Spectral interpretation of late-stage mare basalt mineralogy unveiled by Chang’E-5 samples
Laboratory spectroscopic and X-ray diffraction analyses on the Chang’E-5 lunar soil samples have demonstrated that the spectral features of lunar late-stage mare basalts are representative of iron-rich high-Ca pyroxene rather than olivine.

Decreasing extents of Archean serpentinization contributed to the rise of an oxidized atmosphere
Throughout the Archean, H2 generation via low-temperature ultramafic serpentinization likely helped prevent atmospheric O2 accumulation and continued until the abundance of ultramafic rocks diminished setting the stage for the Great Oxidation Event.

Highly explosive basaltic eruptions driven by CO2 exsolution
Mechanisms that drive highly explosive eruptions of low-viscosity magmas, such as at Sunset Crater volcano, remain uncertain. Here, the authors present evidence for an exsolved CO2 phase ~15 km beneath Sunset Crater that was the critical driver of rapid ...

Quantifying Operational Constraints of Low-Latency Telerobotics for Planetary Surface Operations
NASA's SLS and Orion crew vehicle will launch humans to cislunar space to begin the new era of space exploration. NASA plans to use the Orion crew vehicle to transport humans between Earth and cislunar space where there will be a stationed habitat known ...
