Effect of Foam Faces and Butterfly Auxetic Core on Sandwich Nanoplate Vibration and Buckling

open access: yesZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, Volume 106, Issue 8, August 2026.
ABSTRACT This research examines the thermomechanical vibration and buckling properties of a three‐layer sandwich nanoplate, which consists of foam face layers and a butterfly‐shaped auxetic core. The formulation is developed based on Hamilton's principle and higher‐order shear deformation theory (HSDT), utilizing an analytical Navier‐type solution to ...

Empirical Assessment of Storm‐Time Thermospheric Density Inversion Methods From LEO POD Data

open access: yesEarth and Space Science, Volume 13, Issue 8, August 2026.
Abstract Thermospheric mass density is one of the largest sources of operational uncertainty for spacecraft in low Earth orbit, particularly during geomagnetic storms. The growing population of Global Navigation Satellite System‐equipped satellites presents a data set of opportunity: precise orbit determination (POD) data streams can be used to ...

The Length of Martian Crater Rays and Their Relation to Lunar Cold Spots

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 8, August 2026.
Abstract Impact‐generated crater rays are well‐documented on the Moon, with most appearing as high‐albedo streaks extending radially from a crater's center. On Mars, however, crater rays are significantly rarer and discernible only through thermal imaging due to their lower thermal inertia compared to surrounding terrain.

Near‐Earth Solar Wind Speed of Fast Coronal Mass Ejections

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract Using solar wind and ground magnetometer data for solar cycles 23–25, extreme‐value power‐law models are developed that quantify relationships between near‐Earth solar wind speed and Sun‐to‐Earth transit times of interplanetary coronal mass ejections (ICMEs).

AI Challenge for Satellite Tracking and Orbit Resilience Modeling (STORM‐AI): Data Set, Design, and Results

open access: yesSpace Weather, Volume 24, Issue 8, August 2026.
Abstract Precise thermospheric density forecasting is critical for mitigating satellite drag in Low Earth Orbit (LEO), but traditional empirical models such as MSIS and JB2008 can fail during geomagnetic storms. To evaluate whether AI can better capture this transient behavior, the 2025 MIT ARCLab Prize for AI Innovation in Space asked participants to ...
