Automatic Crater Classification Using a Deep‐Learning‐Based Pipeline
Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 5, October 2026.Abstract Identifying and classifying impact craters on Mars is crucial for understanding the planet's geological history and surface evolution. Traditional crater classification relies on manual annotation methods, which are often limited by human biases and the difficulty of interpreting geomorphological features.

Nighttime Westward Equatorial Electrojet Observed During the January 2026 Geomagnetic Storm
Journal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.Abstract The equatorial electrojet (EEJ) is a narrow band of zonal electric current flowing in the E‐region ionosphere within approximately ±2° $\pm 2{}^{\circ}$ latitude of the magnetic equator. At night, the EEJ is generally considered very weak because of low ionospheric conductivity.

Fast Ejecta from Binary Neutron Star Mergers
, 2020 We investigate the production of fast ejecta from the contact interface in coalescing binary neutron stars. This ejecta expands rapidly enough (velocities > 0.6c) that the r-process freezes out, generating an ultraviolet precursor to the kilonova ...

Journal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.Abstract The lunar surface is heterogeneous in grain size and metallic iron abundance due to diverse histories of space weathering. The spectral and polarimetric properties of the lunar regolith are strongly affected by both grain size and metallic iron particles.

Distal Impact Ejecta Layers: Spherules and More
, 2012 During the formation of large impact structures, layers of melted and crushed rock (ejecta) are deposited over large areas of the Earth\u27s surface. Ejecta thrown farther than 2.5 crater diameters are called distal ejecta.

Ejecta Cone Angle and Ejecta Size Following a Non-perforating Hypervelocity Impact [PDF]
, 2015 The effects of projectile diameter and impact velocity on ejecta cone angle and ejecta size distribution were investigated by striking aluminum alloy 6061-T6 targets with aluminum alloy 2017-T4 spheres at velocities ranging from 2 to 6km/s. The two-stage

The Effects of ICME Composition on the Sputtered Component of the Lunar Exosphere
Journal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.Abstract Charged‐particle sputtering is a fundamental process that contributes to the generation of the Moon’s neutral exosphere. Neutral sputtering rates are dependent on the speed, flux, and composition of the incident charged‐particle populations, all of which are variable at the Moon’s orbit.

Linking Analytic Light-curve Models to Physical Properties of Kilonovae
The Astrophysical JournalIn binary neutron star mergers, lanthanide-rich dynamical ejecta and lanthanide-poor postmerger ejecta have often been linked to red and blue kilonova emission, respectively.
