Geological investigations for self-secondary craters around fresh martian impact craters support the reliability of age determination technique using crater statistics on Mars and suggest that double layered-ejecta deposits may have been emplaced at supersonic speeds.

On 8 January, at 06:59 CET, Bepi, Mio and MTM got as close as 295 km to Mercury’s surface. This sixth flyby is the last time the #BepiColombo trio greet the planet together 👉 https://t.co/jheNFY2pQE

We investigate the geological context of the SLIM landing site at different geological scales, and the possible origins of the surface materials. Our geological analysis provides a framework for the in situ exploration of the #SLIM mission. #Moon #Lunar

A low amount of graphite (~0.7 wt%) mixed with iron can reproduce the reflectances of the various colour units on Mercury, providing important constraints on the characterisation of its magma ocean. Xu, Xiao, Wang & Cui: https://t.co/S6QRMwM7qC

Non-Thermal Escape of Sulfur and Oxygen on Io Driven by Photochemistry https://t.co/akiTVuLHo3 Photochemical escape is more important than Jeans escape for both atomic O and S for when the atmosphere is quiet but only for S during periods of volcanic activity.

Intricate Regolith Reworking Processes Revealed by Microstructures on Lunar Impact Glasses https://t.co/rzxx9G2ePN the abundant protruded and dented microstructures on the glass particles suggest that low-speed events reworked local materials in vapor, melt, and solid phase.

China plans to, as soon as Monday morning, launch a spacecraft to the moon’s surface. If Chang’e-5 is successful, China will be only the third nation to bring lunar rocks back to Earth. https://t.co/rcBO0K6V3j

Lost Volatiles During the Formation of Hollows on Mercury https://t.co/YymwkPGNCH The thickness of halo materials makes a substantial portion of the global budget of C and S in the shallow crust of Mercury, implying ongoing rejuvenation of volatiles in Mercury's recent history.
