Granites are nearly absent in the Solar System outside of Earth. Achieving granitic compositions in magmatic systems requires multi-stage melting and fractionation, which also increases the concentration of radiogenic elements¹. Abundant water and plate tectonics facilitate these processes on Earth, aiding in remelting. Although these drivers are a...

Granites are nearly absent in the Solar System outside of Earth.

Water and plate tectonics facilitate these processes on Earth, aiding in remelting. Although these drivers are absent on the Moon,...

Geothermal heat flux of a body provides a unique look into its internal composition. The geothermal heat flux of the Moon is believed to vary primarily due to the distribution of radiogenic materials both spatially and vertically through the lunar crust. Here, we combine available global orbital, landed mission, returned sample, and meteorite data...

This work analyzes the observations from the Lunar Regolith Penetrating Radar (LRPR) onboard Chang’E-5 to reconstruct the subsurface structure of the regolith under the lander at the drilling site. This is the first stationary Ground-Penetrating Radar (GPR) array to operate on the Moon. Imaging results of pre-drilling and post-drilling measurements...

Aims. We examine data obtained by the Lunar Penetrating Radar (LPR) onboard the Chang'E-4 (CE-4) mission to study the dielectric properties and stratigraphy of lunar regolith on the far side of the Moon. Methods. The data collected from January 2019 to September 2020 were processed to generate a 540 m radargram. The travel velocity of the radar sig...

Passive microwave frequency (~300 MHz to 300 GHz) observations of the Moon have a long history and have been suggested as a plausible orbital instrument for the Moon and other bodies. However, global, orbital multifrequency measurements of lunar passive microwave emission have only recently been made by the Chinese Chang'E‐1 and ‐2 microwave radiom...

To further our understanding of the evolution, selectivity and ecological composition of marine communities following the latest Permian mass extinction, new collections from underrepresented regions in the immediate extinction aftermath are required. Here, we provide new systematic data and the first palaeobiological account of the benthic inverte...
