Reconnection Onset in Overstretched Thin Current Sheets: 3‐D Kinetic Picture

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 11, November 2026.
Abstract Evolution of the magnetotail equilibrium, whose current density iso‐contours are stretched beyond the magnetic field lines due to small ion anisotropy and agyrotropic effects on the scales of the thermal ion gyroradius (the so‐called overstretched thin current sheet) is considered using 3‐D explicit particle‐in‐cell simulations.

An Analysis of the Recent Global Geologic History of Europa: Evidence for Clustered Resurfacing and a Lack of True Polar Wander

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 11, November 2026.
Abstract Global geologic mapping shows that Europa’s surface is made up of an array of features including extensive ridged plains, regions of broad disruption termed chaos terrain, quasi‐linear ridges that span thousands of km, and bands up to 60 km wide that extend for 100–1000s of km.

Laboratory Experiments Identify Meteoritic Organic Precursors for Chlorinated Compounds Detected by the Sample Analysis at Mars (SAM) Instrument at Gale Crater

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 11, November 2026.
Abstract The Viking missions landed two spacecraft on Mars each equipped with a pyrolysis‐gas chromatograph‐mass spectrometer system capable of detecting signs of life. Although working as intended, detections of chloromethane and dichloromethane were initially attributed to terrestrial contamination.

Sulfidation Reaction Mechanisms of Olivine and Diopside at Mercury's Reducing Conditions

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 11, November 2026.
Abstract The surface of Mercury contains elevated amounts of sulfur of up to 4 wt.%. Volcanic degassing of S from the interior of the planet could have initiated sulfidation reactions between the degassed S and surface materials in the planet's past, leading to the observed surface S enrichment.

Quiet Time Ionosphere‐Thermosphere Predictability During Sudden Stratospheric Warmings in TIE‐GCM

open access: yesSpace Weather, Volume 24, Issue 11, November 2026.
Abstract We investigate the predictability of the ionosphere‐thermosphere (IT) region during sudden stratospheric warmings (SSWs) by using subseasonal hindcasts in the Community Earth System Model, version 2 with the Whole Atmosphere Community Climate Model (CESM2 [WACCM6]) to force the lower boundary of the TIE‐GCM.

Cosmic Dust as a Prerequisite for the Formation of Complex Organic Molecules in Space?

open access: yesThe Astrophysical Journal
In cold, dense astrophysical environments dust grains are mixed with molecular ices. Chemistry in those dust/ice mixtures is determined by diffusion and reaction of molecules and radicals.

Influence of Space Weather on Single Event Effects in Aviation When Employing Modern Commercial Sub‐100 nm Electronic Devices

open access: yesSpace Weather, Volume 24, Issue 11, November 2026.
Abstract During November 2025 thousands of commercial aircraft (Airbus A320s) had to be grounded due to the risk of ionizing radiation effects on the avionics system. Safety‐critical systems continue to use modern commercial devices, and therefore an understanding of their responses within enhanced radiation environments is crucial to ensure reliable ...

Exploring Jupiter's Mid‐Latitude Dusk Magnetopause: The Impact of Magnetic Reconnection

open access: yesGeophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract The Juno mission has elucidated magnetosphere processes, structure, and dynamics via multi‐instrument plasma and magnetic field observations. In this study, these instruments are used to identify magnetic reconnection during the Juno extended mission from a survey of 490 magnetopause crossings at the mid‐latitude southern dusk magnetopause ...
