Multiple Reconnection X‐Lines at the Earth's Magnetopause in the Presence of Magnetosheath Flow

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract Magnetic reconnection occurs continuously along long X‐lines at the Earth's magnetopause. The maximum magnetic shear model predicts the locations of these long X‐lines for a wide range of upstream solar wind conditions. One of the more perplexing observational results is that these X‐lines appear to be stationary, even in the presence of ...

Quiet‐Time Equatorial Ionization Anomaly Reversal Observed by the Satellites of Defense Meteorological Satellite Program (DMSP) and Ionospheric Connection Explorer (ICON)

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract We investigated the quiet‐time temporal variations of the Equatorial Ionization Anomaly (EIA) and underlying plasma fountain observed in the topside ionosphere during the various F‐region equatorial E × B drift events recorded by the Jicamarca Incoherent Scatter Radar and simulated by SAMI3.

Rover‐Induced Mineral Transformations: Extent of the Effect for the Mars Science Laboratory and Opportunities for Future Landed Mission

Journal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.
Abstract X‐ray amorphous sulfate hydrates are a substantial component (up to 23 wt%) of the sedimentary rocks and sands analyzed to date by the Mars Science Laboratory Curiosity rover at Gale crater. Recently, the CheMin X‐ray diffractometer observed the amorphization of the crystalline sulfate starkeyite (MgSO4 · 4H2O) upon exposure to the dry and ...

Machine Learning‐Ready Data Sets for the Analysis and Nowcasting of Atmospheric Radiation at Aviation Altitudes

Space Weather, Volume 24, Issue 3, March 2026.
Abstract Nowcasting and forecasting of the radiation environment in the Earth's lower atmosphere are critical for the safety of aircraft and spacecraft crews and passengers. Currently, this problem is addressed by employing statistical and physics‐based models that take into account particle transport and precipitation.

FalconSEED: First Year Review of the Solid‐State Energetic Electron Detector in Geosynchronous Orbit

Space Weather, Volume 24, Issue 3, March 2026.
Abstract We present results from Space Test Program Satellite‐6 (STP Sat‐6) in geosynchronous orbit. The electron detector, named SEED (Solid‐state Energetic Electron Detector) is built entirely from commercial‐off‐the‐shelf (COTS) parts. The instrument data show the electron environment over the entire energy range of detection(14keV−146keV) $(14 ...

Harnessing Satellite Constellations as Signals of Opportunity for an Enhanced Specification of the Satellite Drag Environment in the Critical LEO Regime

Space Weather, Volume 24, Issue 3, March 2026.
Abstract Enhancing the accuracy of orbit predictions for low‐Earth orbit (LEO) satellites and debris is vitally important for satellite owner/operators dedicated to ensuring the safety and sustainability of the LEO environment. Presently, the largest source of error in orbit predictions stems from uncertainties in the estimation of thermospheric mass ...
