X‐ray and γ‐ray Sensing from Aqueous‐Based Lead Sulfide Telluride Nanocomposites

Small, Volume 21, Issue 49, December 10, 2025.
PbSxTey nanoparticles integrate into flexible, size‐scalable aramid polymeric scaffolds, forming percolation paths capable of efficiently transporting the electrons and holes created by penetrating photonic interactions. The resulting nanosemiconductor‐nanofiber composite forms the basis for room‐temperature spectroscopic sensors of X‐rays and γ‐rays ...

Curlometer and gradient techniques: past and future applications

Frontiers in Astronomy and Space Sciences
We review the range of applications and use of multi spacecraft techniques, applicable to close formation arrays of spacecraft, focusing on spatial gradient based methods, and the curlometer in particular. The curlometer was originally applied to Cluster

A Small Pathbreaking Spacecraft: Giants of Space Research (Bernard Blake, Dieter Hovestadt, and Edward Stone)

Perspectives of Earth and Space Scientists, Volume 6, Issue 1, December 2025.
Abstract The Solar, Anomalous, and Magnetospheric Explorer (SAMPEX) mission launched in July 1992 was the first NASA “Small Explorer” project. It had the goal to show how space missions could be developed much more rapidly than had become the situation in the 1980s and 1990s.

Influence of the Earthward and Tailward Ion Flows on the Lunar Surface Water in the Magnetotail

Journal of Geophysical Research: Planets, Volume 130, Issue 12, December 2025.
Abstract Earth wind, namely the particles from the Earth's magnetotail, is an important source of lunar water. Besides tailward flow incident on the lunar nearside when the Moon is in the magnetotail, there exists earthward flow bombarding the farside, affecting the distribution and preservation of lunar water.

Redefining SAR Arc Generation: The Competing Roles of Magnetospheric and Ionospheric Energy Injection

AGU Advances, Volume 6, Issue 6, December 2025.
Abstract Stable auroral red (SAR) arcs are luminous subauroral emissions produced by the collisional excitation of oxygen atoms during geomagnetically active times. While traditionally attributed to inner magnetospheric electron heating, recent observations and simulations challenge the exclusivity of this mechanism.

Community Voices on the Future of Radiation Belt Research: A Summary of the 2024 GEM Radiation Belt Focus Group Round‐Table Discussion

Earth and Space Science, Volume 12, Issue 12, December 2025.
Abstract Earth's radiation belts are the regions where highly energetic charged particles are trapped by Earth's magnetic field, posing significant risks to the satellites and other space‐based technologies. Understanding the dynamics of the radiation belts is critical not only for advancing fundamental plasma physics but also for predicting and ...
