Abstract As crewed space missions set course for the Moon and beyond, astronauts will experience prolonged exposure to Galactic Cosmic Rays (GCR) and potentially intense Solar Proton Events (SPEs), both of which pose significant short‐ and long‐term health risks.

Since fast head-on coronal mass ejections and their associated shocks represent potential hazards to the space environment of the Earth and even other planets, forecasting the arrival time of the corresponding interplanetary shock is a priority in space ...

Finding Novel Precursors for Solar Wind Stream Interaction Regions With Interpretable Deep Learning
Abstract Solar wind stream interaction regions (SIRs) drive recurrent geomagnetic storms, yet most existing catalogs rely on expert inspection and simple thresholds that are subjective and can miss events with complex morphologies. We present SIREN (SIR Encoder Network), a lightweight Transformer‐based model for per‐timestep SIR detection from in situ ...

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 ...

Atypical Particle Heating at a Supercritical Interplanetary Shock [PDF]
We present the first observations at an interplanetary shock of large amplitude (> 100 mV/m pk-pk) solitary waves and large amplitude (approx.30 mV/m pk-pk) waves exhibiting characteristics consistent with electron Bernstein waves.

Type‐III Solar Radio Bursts at Mars: A 16.5‐Year Catalog From Mars Express‐MARSIS at 0.1–5.5 MHz
Abstract The most intense radio feature in the Solar System are the solar Type‐III radio bursts, which are associated with electron beams that propagate along open magnetic field lines. Although solar radio bursts have been studied since the 1940s, observations remain mainly restricted within 1 AU.

Post-shock spikes: A new feature of proton and alpha enhancements associated with an interplanetary shock wave [PDF]
Abrupt and prolonged enhancements in the intensities of 100 to approximately 2000 keV nucleon protons and alpha particles observed in interplanetary space are interpreted as particle populations confined between an interplanetary shock front and a ...

Reconfiguration of Mercury's Exosphere During Strong Space Weather Events
Abstract Mercury is exposed to various space weathering processes, which alter the surface and cause emission of atoms and molecules into the exosphere. The exosphere thus allows remote insights into the surface composition and erosion processes, with the emission of refractory elements such as Ca and Mg typically being dominated by micrometeoroid ...
