Soil Science Society of America Journal, Volume 90, Issue 5, September/October 2026.Abstract This study examined the noble gas inventories of different grain size fractions of lunar soil 61220 as a proxy for solar wind‐implanted volatiles of in situ resource utilization (ISRU) interest (e.g., H2O and noble gases). Sample 61220 is representative of a “dry” highland regolith, comparable to those that may be sampled by missions exploring

Mercury's Circumsolar Dust Ring as an Imprint of a Recent Impact
The Planetary Science Journal, 2023 A circumsolar dust ring has been recently discovered close to the orbit of Mercury. There are currently no hypotheses for the origin of this ring in the literature, so we explore four different origin scenarios here: the dust originated from (1) the ...

Global Circulation of Martian Ionospheric Currents Revealed by Magnetometer Data
AGU Advances, Volume 7, Issue 6, September 2026.Abstract In the dynamo region of the Martian ionosphere, a large‐scale current is generated by charge separation: ions collide with neutrals while electrons preferentially gyrate around local magnetic field lines. Using MAVEN magnetometer data and a physics‐informed neural network constrained by Ampère's law and Gauss's law for magnetism (the Neural ...

Journal of Geophysical Research: Space Physics, Volume 131, Issue 9, September 2026.Abstract The Earth's ionosphere is sensitive to variations in solar irradiance associated with the 11‐year and the 27‐day solar cycles (SCs). Previous studies have suggested that the peak altitude of the 27‐day SC response in ionospheric electron density is significantly higher than that of the 11‐year SC response, but the underlying mechanism remains ...

Earthward Transport of Lunar Metallic Ions: Implications of Heavy Ions in the Magnetosphere
Journal of Geophysical Research: Space Physics, Volume 131, Issue 9, September 2026.Abstract Low‐charge‐state heavy ions in Earth's magnetosphere were thought to originate from the ionosphere. However, Observations from the Geotail mission have detected the presence of singly charged metallic ions, such as Fe+ ${\mathrm{F}\mathrm{e}}^{+}$, whose abundances vary depending on the Moon's location, alongside their density ratios to O ...

Auger spectroscopy of stratospheric particles : the influence of aerosols on interplanetary dust [PDF]
, 1985 Particle collections from the stratosphere via either the JSC Curatorial Program or the U2 Program (NASA Ames) occur between 16km and 19km altitude and are usually part of ongoing experiments to measure parameters related to the aerosol layer.

Different Frontier, Same Legal Script? On the Course of Replicating Earth's Patterns in Space
The Modern Law Review, Volume 89, Issue 5, Page 723-759, September 2026.As states and private actors expand their activities in outer space, the international legal framework governing this domain risks extending longstanding structures of global inequality beyond Earth. This article examines how international space law, shaped by a broader disciplinary pattern of reactive legal development, is poised to reproduce ...

Meteoritics &Planetary Science, Volume 61, Issue 9, Page 2269-2283, September 2026.Abstract We report the discovery of the second (Al,Cu)‐alloy–bearing micrometeorite, FB‐A2, recovered from Mount Gariglione (southern Italy), representing the sixth such occurrence worldwide. Although chondritic in nature, FB‐A2 differs markedly from previously described microspherules.
