Whistler‐Mode Chorus Wave Duct Propagation Caused by Ultralow Frequency Wave: Event Analysis and Ray‐Tracing Simulation

open access: yesGeophysical Research Letters, Volume 52, Issue 17, 16 September 2025.
Abstract This study presents observational evidence and ray‐tracing simulations demonstrating ultra‐low frequency (ULF) wave‐induced duct propagation of whistler‐mode waves. Cluster satellite observation reveals chorus propagating quasi‐parallelly at high latitudes and ULF waves.

Ultra‐Compact Cellular Structured Bio‐Carbon Aerogels Supported PCM for Exceptional Thermal Insulation and Radiation Shielding for Space Applications

open access: yesENERGY &ENVIRONMENTAL MATERIALS, Volume 8, Issue 5, September 2025.
Irradiation‐induced high‐efficiency thermal insulation applied to complex thermal management environments: a novel biomass‐based phase change thermal insulation material (CCA/PEG). Integrating phase change materials (PCM) into thermal insulation materials offers a novel approach to aerospace thermal protection.

Spacecraft Antennas [PDF]

open access: yes, 1990
Some of the various categories of issues that must be considered in the selection and design of spacecraft antennas for a Personal Access Satellite System (PASS) are addressed, and parametric studies for some of the antenna concepts to help the system ...

An exploration of market mechanisms to the wicked problem of space debris 太空垃圾棘手问题的市场机制探究 Una exploración de los mecanismos del mercado para resolver el complejo problema de los desechos espaciales

open access: yesRisk, Hazards &Crisis in Public Policy, Volume 16, Issue 3, September 2025.
Abstract Near‐earth orbits are becoming congested because of a rapid growth in the number of satellites and space debris, which presents a real threat to the sustainable use of space and the safety of the Earth. Despite space scientists and public policymakers having been actively seeking solutions for decades, solving the problem has been put off ...

Measurement of the electric fluctuation spectrum of magnetohydrodynamic turbulence

open access: yes, 2005
Magnetohydrodynamic (MHD) turbulence in the solar wind is observed to show the spectral behavior of classical Kolmogorov fluid turbulence over an inertial subrange and departures from this at short wavelengths, where energy should be dissipated.

Global Effects of Magnetic Anomalies on the Near‐Surface Lunar Plasma Environment

open access: yesJournal of Geophysical Research: Space Physics, Volume 130, Issue 9, September 2025.
Abstract The interaction between lunar magnetic anomalies and the solar wind plasma creates unique structures known as “lunar mini‐magnetospheres,” which reflect and partially shield the lunar surface from impinging solar wind protons. Using data from the Sub‐KeV Atom Reflecting Analyzer onboard Chandrayaan‐1, we produce new surface maps of energetic ...
