Remote Compositional Analyses of Space-weathered Lunar Maria
The Planetary Science JournalVisible-to-shortwave infrared (VSWIR) reflectance spectroscopy has revolutionized our understanding of planetary surface compositions. However, space-weathering processes on airless bodies complicate quantitative compositional analyses.

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.Abstract Using Van Allen Probes data (2013–2015), we report that highly oblique chorus waves frequently occur in low‐density regions where fpe/fce≈3 ${f}_{\text{pe}}/{f}_{\text{ce}}\approx 3$. These waves exhibit an electric‐to‐magnetic energy ratio PE/c2PB>0.5 $\sqrt{{P}_{\mathrm{E}}/{c}^{2}{P}_{\mathrm{B}}} > 0.5$, much higher than the typical <0.1 ${

Petrography, Mineralogy and Geochemistry of Lunar Meteorite Sayh al Uhaymir 300
, 2008 We report here the petrography, mineralogy, and geochemistry of lunar meteorite Sayh al Uhaymir 300 (SaU 300). SaU 300 is dominated by a fine-grained crystalline matrix surrounding mineral fragments (plagioclase, pyroxene, olivine, and ilmenite) and ...

Sintering lunar regolith pellets: a comparison of four samples from Apollo 11, 15, and 16
Materials Today AdvancesLunar regolith sintering is proposed as a technique to produce consolidated objects on the lunar surface from locally sourced materials. Understanding the sintering behaviour of real lunar regolith is necessary to optimise this process, however, due to ...

Bounce Resonance Between ULF Waves and Electrons in the Dayside Outer Magnetosphere
Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.Abstract Resonant interactions between ultra‐low‐frequency (ULF) waves and particles are critical for energy transfer in the Earth's magnetosphere, and have been extensively investigated in the inner magnetosphere. However, resonant processes between ULF waves and electrons in the dayside outer magnetosphere remain largely unexplored.

A Physics-Guided Diffusion Unmixing Model for Global Lunar Mineral Abundance Mapping
IEEE Journal of Selected Topics in Applied Earth Observations and Remote SensingAccurate global mapping of lunar regolith minerals is critical for understanding the geological evolution and resource potential of the Moon. However, spectral unmixing algorithms originally designed for terrestrial remote sensing often perform poorly ...

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.Abstract Mercury experiences the most intense and variable solar wind (SW) conditions in the solar system due to its close, eccentric orbit about the Sun. In addition to variation driven by coronal source and solar cycle, the SW arriving at Mercury varies periodically as the planet's heliocentric distance changes by over 50% per orbit.
