Emissions Poised to Rocket: Modeling the Environmental Impacts of Low Earth Orbit Satellite Constellations

Earth's Future, Volume 14, Issue 11, November 2026.
Abstract The proliferation of satellite megaconstellations in low Earth orbit represents a significant advancement in global broadband connectivity. However, we urgently need to understand the potential environmental impacts, particularly greenhouse gas (GHG) emissions associated with these constellations.

Hysteretic Dynamics of Stream Network Expansion and Contraction Revealed Through High‐Resolution Integrated Hydrological Modeling

Water Resources Research, Volume 62, Issue 11, November 2026.
Abstract As landscapes cycle through wetting and drying, stream networks expand and contract, driving material export and biogeochemical transformations with important implications for water quality and ecosystem function. Because it is challenging to measure the extent (L) $(L)$ of the active network, streamflow (Q $Q$) is often used as a proxy ...

EL‐PASO: An Open‐Source Python Library for Processing and Standardizing Particle Measurements Taken in Space

Earth and Space Science, Volume 13, Issue 11, November 2026.
Abstract In this article, we present EL‐PASO (ELaborative Particle Analysis from Satellite Observations), an open‐source Python library for processing and standardizing in situ particle measurements taken in space. EL‐PASO aims to address the challenges posed by the diverse data formats and metadata standards used by different space missions.

Soft X‐Ray Telescopes of the Future: Trade Study of Micro‐Pore Optic Size for Imaging Dayside Magnetospheric Features

Journal of Geophysical Research: Space Physics, Volume 131, Issue 11, November 2026.
Abstract This study compares the capabilities of different sized micro‐pore optic (MPO) based soft X‐ray telescopes and their ability to observe features and phenomena of the magnetosheath at Earth. The basic science is the starting point and different instrument properties are applied to test which would be capable of studying features of the near ...

ELFIN Statistics of Electron Strong Diffusion in the Inner Magnetosphere

Journal of Geophysical Research: Space Physics, Volume 131, Issue 11, November 2026.
Abstract Pitch‐angle diffusion of trapped electrons driven by whistler‐mode and EMIC waves and by field‐line curvature scattering (FLCS) plays an important role in energetic and relativistic electron loss from the inner magnetosphere. The strong diffusion regime, characterized by a nearly full loss cone, rarely occurs, but is expected to account for a ...
