Lunar Trailblazer Spacecraft Tracking and Mission Recovery Attempt: Characterization of Status and Behavior of a Non‐Cooperative Object in Cis‐Lunar Space

Earth and Space Science, Volume 13, Issue 8, August 2026.
Abstract Unexpectedly following launch, the Lunar Trailblazer mission experienced software anomalies that led it to orient solar panels away from the sun and lose communication with Earth. This paper describes efforts to determine the spacecraft state and attempt recovery of the mission's science at the Moon.

Comparing Monte Carlo Models of Impact Alteration of Planetary Atmospheres

Journal of Geophysical Research: Planets, Volume 131, Issue 8, August 2026.
Abstract One process that affects atmospheric surface pressure is impact bombardment. The evolution of a planet's atmosphere under impact bombardment is an open question. We use a Monte Carlo method to evolve a range (0.006–92.5 bar) of initial atmospheres at Mars, Earth, and Venus under bombardment of 5×106 $5\times 1{0}^{6}$ impactors using seven ...

YOLO‐Based Detection and Localization of Rocket Induced Traveling Ionospheric Disturbances

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 4, August 2026.
Abstract During rocket launches, atmospheric disturbances significantly impact the ionosphere, generating Traveling Ionospheric Disturbances (TIDs). These disturbances can affect radio communications and navigation systems and may pose risks to high‐speed aerospace vehicles.

Assimilation of All‐Sky TROPICS Constellation Radiance Data in the NASA Goddard Earth Observing System (GEOS)

Earth and Space Science, Volume 13, Issue 8, August 2026.
Abstract This study examines the impact of assimilating all‐sky microwave radiances from the Time‐Resolved Observations of Precipitation structure and storm Intensity with a Constellation of Smallsats (TROPICS) mission within the NASA Global Earth Observing System (GEOS) data assimilation and forecasting framework based on the Gridpoint Statistical ...

Jovian Auroral Proton Precipitation

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract The total power of the Jovian aurora is about 1013–1014 W with ultraviolet emission observed in the Lyman and Werner bands of molecular hydrogen. X‐ray, radio, and infrared emissions have also been observed. The Jovian Auroral Distributions Experiment and the Jovian Energetic Particle Detector Instrument onboard the Juno spacecraft, orbiting ...

Cusp Ion Dispersions and Their Relation to the Dayside Magnetic Reconnection Location: TRACERS First Results

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract A key process in solar‐terrestrial interactions is magnetic reconnection at the magnetopause. In addition to in situ observations of plasma entry at the magnetopause, some of the important global aspects of magnetic reconnection are addressed using plasma observations in the Earth's magnetospheric cusp region. Ions injected at the magnetopause

Self‐Limiting of Artificial Electron Radiation Belts: Evidence From the Starfish Prime High‐Altitude Nuclear Explosion

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract The 1962 Starfish Prime high‐altitude 1.4‐megaton nuclear detonation injected large amounts of fission‐produced energetic electrons into the inner magnetosphere (L = 1.12), creating an intense artificial radiation belt that persisted for years. In this study, we revisit historical data from this unprecedented event to investigate the potential

Structural Evolution of Antigorite by High‐Velocity Impacts

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract Serpentine is a major hydrous mineral present in hydrous asteroids that have evolved through planetary impacts. Understanding its dynamic behavior is essential to elucidate the redistribution and retention of water during high‐velocity impact processes. The shock response of antigorite was examined at pressures up to 106 GPa using laser‐driven
