Elastic Properties of Titan Tholins Revealed by Brillouin Spectroscopy
Journal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.Abstract Titan tholins, complex organic solids synthesized by simulating photochemical processes in Titan's atmosphere, are widely regarded as analogs to organic surface materials on the Saturnian moon. Their mechanical properties are critical for understanding the evolution of Titan's geomorphology and crustal layering.

Space Weather, Volume 24, Issue 10, October 2026.Abstract Shortwave fadeout (SWF) is a typical dayside high‐frequency radio disturbance caused by solar flare‐induced ionospheric ionization enhancement. Using newly built Chinese Dual Auroral Radar Network (CN‐DARN) observations, we investigate two X‐flare‐driven SWFs during the May 2024 geomagnetic superstorm (SYM‐H = −518 nT), on 10 May (pre‐storm ...

Space Weather, Volume 24, Issue 10, October 2026.Abstract Accurate forecasting of global ionospheric total electron content (TEC) is important for Global Navigation Satellite Systems (GNSS) performance and satellite communications. This study proposes a driver framework based on the spectral whitening method (SWM). We combine a new high‐latitude geomagnetic disturbance index with previously developed

Calibration Method of Empirical Atmospheric Density Based on Physics‐Informed Neural Networks
Space Weather, Volume 24, Issue 10, October 2026.Abstract Thermospheric density is a critical parameter for low Earth orbit satellite applications, including orbit prediction, collision risk assessment, and atmospheric drag analysis. However, empirical atmospheric density models exhibit significant uncertainties under disturbed space weather conditions, while purely data‐driven approaches may not ...

Space Weather, Volume 24, Issue 10, October 2026.Abstract The Earth's magnetopause is a key boundary governing solar wind–magnetosphere coupling. The Solar wind Magnetosphere Ionosphere Link Explorer (SMILE) mission will provide global soft X‐ray imaging of the magnetosphere through solar wind charge exchange (SWCX) emission, offering a new opportunity for remote sensing of magnetopause dynamics ...
