Radiative Forcing and Ozone Depletion of a Decade of Satellite Megaconstellation Missions

Earth's Future, Volume 14, Issue 5, May 2026.
Abstract Satellite megaconstellations (SMCs) are driving rapid increases in rocket launch and re‐entry rates, emitting pollutants throughout the atmosphere. The environmental impact of SMCs lacks characterization to determine the need for regulation. We utilize a global 3D emission inventory of recent (2020–2022) space activity that distinguishes SMC ...

Soft X‐Ray Emission From Saturn's Magnetosheath II: Solar Wind Driving

Journal of Geophysical Research: Space Physics, Volume 131, Issue 5, May 2026.
Abstract Saturn's magnetosphere is dominated by Enceladus‐sourced neutrals, which spread throughout the system into the magnetosheath. The neutrals can charge exchange with highly charged solar wind ions, causing soft X‐ray emission (<2 ${< } 2$ keV) upon de‐excitation of the ion.

Constraining the Hydration of Clay Minerals and Abundances of Amorphous Phases in Gale Crater, Mars

Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract Both water and organic matter are required for the development and persistence of life. Phyllosilicates (clay minerals) have high surface areas that easily sorb water and organic matter. The Curiosity rover has investigated several hundred meters of stratigraphy in Gale crater, including where clays were detected from orbit.

GOES‐R Series X‐Ray Sensor (XRS): 2. On‐Orbit Measurements and Calibrations

Journal of Geophysical Research: Space Physics, Volume 131, Issue 5, May 2026.
Abstract An X‐Ray Sensor (XRS) has been onboard each of the National Oceanic and Atmospheric Administration (NOAA) Geostationary Operational Environmental Satellites (GOES) since 1975. XRS measures full‐disk soft X‐ray irradiance in two wavelength bands, 0.05–0.4 nm and 0.1–0.8 nm.

A Two‐Step Artificial Intelligence Approach for Correcting Space Weathering Effects in the Lunar Reconnaissance Orbiter Diviner Christiansen Feature Image

Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract Space weathering substantially distorts the Christiansen feature (CF) observed by Lunar Reconnaissance Orbiter (LRO) Diviner thermal infrared radiometer, obscuring the intrinsic compositional and thermophysical signals of lunar surface silicate minerals.
