The Role of Propellant Type, Re‐Entry, and Plume Reactions in the Atmospheric Impacts of Spaceflight

Earth's Future, Volume 14, Issue 5, May 2026.
Abstract The space industry is growing rapidly, and over the coming years the number of annual rocket launches is expected to increase further. This increases the sector's emissions and environmental effects, both of which are not yet comprehensively understood.

Modeling the Delivery of Mercury's Polar Ice by a Volatile‐Rich Impact

Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract Permanently shadowed regions near Mercury's poles are thought to harbor significant deposits of water ice, the origin of which remains to be conclusively determined. One leading hypothesis is that most of the water observed today may have been delivered by a relatively recent, volatile‐rich impact comparable in scale and age to that which ...

Impact Plasma Amplification of the Ancient Mercury Magnetic Field

Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract Spacecraft measurements of Mercury indicate that it has a core dynamo with a surface field of 200–800 nT. These data also indicate that the northern hemisphere crust contains remanent magnetization likely produced by an ancient magnetic field. The inferred magnetization intensity is consistent with a wide range of paleofield strengths (0.2–50 ...

Investigating the Impact of Rocket Exhaust on Ionospheric Disturbances

Space Weather, Volume 24, Issue 5, May 2026.
Abstract The study of chemical releases into the ionosphere is crucial for understanding ionospheric dynamics and managing space environmental effects. In this work, we investigate the impact of rocket exhaust emissions, particularly CO2 and H2O, on electron density in the ionosphere.
