Water Activity and the Challenge for Life on Early Mars
TL;DR: The salinity of well-documented surface waters often exceeded levels tolerated by known terrestrial organisms, indicating that the habitability of these waters depends critically on water activity.

Geochemical Constraints on the Growth of the Continental Crust
TL;DR: In this paper, it was shown that the Archean upper crust was considerably more mafic than the present-day upper crust, and that if there have been any additions to the post-Archean crust, they must have had similar composition to the upper crust itself.

TL;DR: The SuperCam body unit (BU) of the Mars 2020 rover as mentioned in this paper was designed to receive light from the mast unit via a 5.8 m opti-cal fiber and the light is split into three wavelength bands by a demultiplexer, and routed via fiber bundles to three optical spectrometers, two of which (UV and violet; 245-340 and 385-465 nm) are crossed Czerny-Turner reflection spectrometer, nearly identical to their counterparts on ChemCam.

TL;DR: Localized zinc enrichments that provide evidence for hydrothermal alteration and gypsum-rich veins that were precipitated from liquid water at a relatively low temperature provide a compelling case for aqueous alteration processes in this area at ancient times.
Rare earth element geochemistry and the “tetrad” effect
TL;DR: The tetrad effect is found in the rare earth elements (La-Lu) and results from increased stability at quarter, half, three-quarter, and complete filling of the 4f electron shell as mentioned in this paper.
