The Isotopic Variation of K and Fe in Apollo 17 Double Drive Tube 73001/2 and Implications for Regolith History and Space Weathering

open access: yesJournal of Geophysical Research: Planets, Volume 130, Issue 4, April 2025.
Abstract Space weathering alters the surface materials of airless planetary bodies; however, the effects on moderately volatile elements in the lunar regolith are not well constrained. For the first time, we provide depth profiles for stable K and Fe isotopes in a continuous lunar regolith core, Apollo 17 double drive tube 73001/2.

Correlation Between the Delay and Rise Time of VLF/LF Amplitudes During 20 Solar X‐Ray Flares Observed in February 2014 at Mid‐Latitude

open access: yesRadio Science, Volume 60, Issue 4, April 2025.
Abstract During daylight hours, the concentration of electrons in the ionosphere can be amplified by solar flares, which may subsequently influence the propagation of radio waves. Previous research on Very Low Frequency (VLF) signals focused on X‐class and M‐class flares.

The Magnetosphere‐Ionosphere‐Ground Responses to the May 2024 Super Solar Storm

open access: yesSpace Weather, Volume 23, Issue 4, April 2025.
Abstract Earth suffered the attack of the strongest geomagnetic storm in the last 20 years (Kp = 9, Dst∼ ${\sim} $ −400 nT) occurred on 11 May 2024. Taking advantage of the LEO multi‐parameter CSES satellite (launched in 2018) with a large inclination angle 97° $97{}^{\circ}$, with the joint observations of NOAA and GOES, we present a comprehensive ...

NAIRAS Version 3 Atmospheric Ionizing Radiation Validation: Comparisons to RaD‐X Measurements

open access: yesSpace Weather, Volume 23, Issue 4, April 2025.
Abstract The Nowcast of Aerospace Ionizing RAdiation System (NAIRAS) model predicts dosimetric and radiative flux quantities for assessing human radiation exposure levels and radiation effects on flight electronic systems from the surface of the Earth to deep space. NAIRAS version 3 includes many updates and improvements to the model.
