The Constraint of Crewed Mars Missions Based on Current Radiation Dose Measurements
Space Weather, Volume 24, Issue 3, March 2026.Abstract Crewed missions to Mars will be a milestone of future space exploration programs. However, the absence of Earth's magnetic field leaves astronauts directly exposed to unattenuated energetic particles in deep space, primarily galactic cosmic rays (GCRs), resulting in significantly higher radiation levels and enhanced health risks. Understanding

Space Weather, Volume 24, Issue 3, March 2026.Abstract The CLEAR Space Weather Center of Excellence's solar energetic particle (SEP) model, SOlar wind with FIeld lines and Energetic particles (SOFIE), was run and evaluated on‐site during the Space Weather Prediction Testbed (SWPT) exercise at the National Oceanic and Atmospheric Administration's Space Weather Prediction Center (NOAA/SWPC) in May ...

An Overview of Solar Orbiter Observations of Interplanetary Shocks in Solar Cycle 25
The Astrophysical Journal Supplement SeriesInterplanetary (IP) shocks are fundamental constituents of the heliosphere, where they form as a result of solar activity. We use previously unavailable measurements of IP shocks in the inner heliosphere provided by Solar Orbiter, and present a survey of

Kinetic Structure of an Interplanetary Shock Observed at Two Heliocentric Longitudes
Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.Abstract Collisionless shocks convert bulk flow energy into heat, electromagnetic fields, and non‐thermal particle populations. Recent studies suggest that downstream magnetic oscillations could play an important role in ion‐scale energy dissipation at low‐Mach‐number shocks; however, the specific shock and plasma parameters involved remain poorly ...

SH41B-2777: The acceleration of particles at propagating interplanetary shocks
, 2018 Enhancements of charged energetic particles are often observed at Earth following the eruption of coronal mass ejections (CMEs) on the Sun. These enhancements are thought to arise from the acceleration of those particles at interplanetary shocks forming ahead of CMEs, propagating into the heliosphere.

Spectral Properties and Energy Injection in Mercury's Magnetotail Current Sheet
Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.Abstract Mercury's magnetotail hosts a thin and highly dynamic current sheet (CS), where magnetic reconnection and strong fluctuations frequently occur. Here, we statistically analyze magnetic field power spectra across 370 magnetotail CSs observed by MESSENGER.

Martian Atmospheric Loss Through Foreshock Transient Events
Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.Abstract At Mars, the MAVEN spacecraft has made observations of Hot Flow Anomalies (HFAs) in the foreshock. Due to the bow shock's proximity to the planet, it is theorized that HFAs contribute to atmospheric escape at Mars through the excavation of ionospheric ions.

Astronomy & AstrophysicsAims. The study investigates the relevance of the seed particle population in the results of particle acceleration in interplanetary shock waves, when wave–particle interactions are treated self-consistently. Methods. We employed the SOLar Particle Acceleration in Coronal Shocks (SOLPACS) model, which is a proton acceleration simulation in shocks with ...

Energetic particle investigation using the ERNE instrument
Annales GeophysicaeDuring solar flares and coronal mass ejections, nuclei and electrons accelerated to high energies are injected into interplanetary space. These accelerated particles can be detected at the SOHO satellite by the ERNE instrument.
