Terrestrial Runoff Divides the Central Arctic Ocean and Shapes the Biologically Relevant Marine Lightscape

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract The Arctic Ocean is undergoing drastic changes in its sea ice cover, but is also optically complex. Observations from summer 2022 across the western Eurasian Basin, show increased colored dissolved organic matter (CDOM) absorption from terrestrial‐derived runoff within the Transpolar Drift (TPD) in the Amundsen Basin, extending down to a depth

Mineralogical Mapping of Pyroxene and Anorthosite in Dryden Crater Using M³ Hyperspectral Data

Engineering Proceedings
This study investigates the mineral composition of the lunar Dryden Crater using Moon Mineralogy Mapper (M3) data. A RGB false-color composite reveals distinct pyroxene, anorthosite, and possibly spinel distribution patterns.

SPECTRAL UNMIXING BASED CONSTRUCTION OF LUNAR MINERAL ABUNDANCE MAPS [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2017
In this study we apply a nonlinear spectral unmixing algorithm to a nearly global lunar spectral reflectance mosaic derived from hyper-spectral image data acquired by the Moon Mineralogy Mapper (M3) instrument.

Large‐Scale Magnetosheath Jets Formed by Shock‐Discontinuity Interactions: A Three‐Dimensional Global Hybrid Simulation

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract Magnetosheath high‐speed jets with enhanced dynamic pressure are common in Earth's magnetosheath and can impinge on the magnetopause, driving pronounced boundary deformation. Recent observations indicate that shock–discontinuity interactions (SDIs) can generate magnetosheath jets, but the formation mechanism is still unclear.

Space Weathering–driven Coupled Loss of S and Fe from Troilite on the Moon

The Astrophysical Journal Letters
Space weathering of sulfides is a key mechanism for the sulfur and iron anomalies on the surfaces of the Moon and other airless bodies. However, the detailed pathway for how space weathering modifies S and Fe contents in iron sulfide remains poorly ...

Space Weathering Properties of Chang’e-6 Soils and Implication for Regolith Evolution of Young Lunar Maria

The Astrophysical Journal Letters
Lunar soil samples from young maria (formed 3.0 Ga) and higher than the ∼21% found in the Chang’e-5 soils from younger mare (∼2.0 Ga). However, our spectroscopic study reveals that the Chang’e-6 soils are well developed, with high maturity, weak ...

In situ detection of boron by ChemCam on Mars [PDF]

, 2017
We report the first in situ detection of boron on Mars. Boron has been detected in Gale crater at levels Curiosity rover ChemCam instrument in calcium-sulfate-filled fractures, which formed in a late-stage groundwater circulating mainly in phyllosilicate-

Mid‐Infrared Compositional Spectral Parameters for the Lunar Thermal Mapper Instrument Onboard Lunar Trailblazer

Earth and Space Science, Volume 13, Issue 5, May 2026.
Abstract The Lunar Trailblazer mission launched in February of 2025 with the goal of characterizing lunar surface water through a targeted campaign. One instrument on the mission, the Lunar Thermal Mapper (LTM), was tasked with measuring the surface temperature to compare with maps of the form and abundance of water on the lunar surface.

Petrogenesis of Chang’e-6 Basalts and Implication for the Young Volcanism on the Lunar Farside

The Astrophysical Journal Letters
Mare basalts from lunar farside are pivotal for unraveling lunar nearside-farside dichotomies and global thermal history. The Chang’e-6 (CE-6) mission conducted the first sampling from a young basaltic unit within the Apollo basin on the lunar farside ...
