Nanoscale space weathering features in mature lunar soil revealed by TEM and APT

Meteoritics &Planetary Science, Volume 61, Issue 8, Page 2048-2072, August 2026.
Abstract Space weathering significantly alters the optical, chemical, and structural properties of lunar regolith at micro‐ and nanoscales; yet detailed nanoscale variability within individual soils remains underexplored. Here we apply transmission electron microscopy (TEM) and atom probe tomography to four mineral grains (olivine, ilmenite, and two ...

REINA-ΦΩ v7.0∞: A Physically-Anchored Quantum-Ethical Organ for Interplanetary AI Swarm Enforcement

1. Introduction Most AI safety mechanisms are implemented as software policies: filters, guards, oversight agents. In high-risk interplanetary environments, this is not enough. A sufficiently advanced or compromised swarm can rewrite its own software stack.

Enhancement of Dayside Westward Electrojet: Triggering Conditions and Current Closures

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Geomagnetic substorms are a major path for energy storage and release in the magnetosphere, which typically occur in the midnight sector with a strong enhancement of westward electrojets. However, by analyzing 37,940 events from a substorm list, about 3% of events unexpectedly initiated in the noon sector.

Ultra‐Low‐L Sub‐MeV Electron Microbursts During the May 2024 Super Storm

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract During the May 2024 super storm, we identified sub‐second microburst‐type relativistic electron precipitation events at McIlwain's L∼2 $L\sim 2$ in low‐Earth orbit using the Gamma‐ray Burst Monitor (CGBM) onboard the CALorimetric Electron Telescope on the International Space Station.

TRACERS Small‐Scale Field‐Aligned Currents and Intense GPS Amplitude and Phase Scintillations in the Nightside Auroral Region

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract We present conjugate observations of ionospheric small‐scale magnetic perturbations (dB) $(dB)$ and GPS scintillations from the Tandem Reconnection and Cusp Electrodynamics Reconnaissance Satellites (TRACERS) and the Canadian High Arctic Ionospheric Network (CHAIN) during a storm‐time substorm on 9 August 2025 in the nightside auroral region ...
