Characterizing Low-Energy Charged Particles in the Magnetosphere with the LEM CubeSat Spectrometer Project: Detector Concept and Hardware Characterisation

Universe, 2023
An accurate flux measurement of low-energy charged particles trapped in the magnetosphere is necessary for space weather characterization and to study the coupling between the lithosphere and magnetosphere, which allows for the investigation of the ...

Polygon‐Based Spectral Reflectance Sampling for Real‐Time River Discharge Estimation

Water Resources Research, Volume 62, Issue 9, September 2026.
Abstract River discharge estimation (RDE) methods are traditionally prone to high costs, vulnerability to extreme events, and are constrained by real‐time data availability. Current remote sensing‐based RDE approaches mainly extract basic river features such as width and water surface elevation, but rarely exploit the full spectral information from ...

Beyond SMAP: Can GNSS‐R Platforms Ensure Continuity of Global Soil Moisture Observations?

Water Resources Research, Volume 62, Issue 9, September 2026.
Abstract The absence of a definitive follow‐on strategy for the Soil Moisture Active Passive (SMAP) mission, which has already surpassed its planned mission lifetime, presents a significant challenge for the hydrological science community. GNSS‐Reflectometry (GNSS‐R), which exploits reflected satellite navigation signals, has emerged as a rapidly ...

Personalization and Fortification of In‐Space Manufactured Emulsified Beverages for Long‐Term Space Travel

Comprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 5, September 2026.
ABSTRACT The current trend of individualized food items (nutrient content and flavor) can be particularly valuable to support people's health and well‐being in isolated environments where access to fresh foods and diverse nutrition is difficult. At the same time, bioactive compounds and micronutrients can be employed to countermeasure any health ...

Floods From Space: How Remote Sensing, AI, and Cloud Platforms Are Reshaping Disaster Risk Reduction

Journal of Flood Risk Management, Volume 19, Issue 3, September 2026.
ABSTRACT Flooding remains one of the most damaging climate‐related hazards globally, yet flood remote sensing has historically developed largely along sensor‐specific pathways. This review addresses the need for a systematic and decision‐oriented synthesis of how space‐borne remote sensing has evolved toward integrated flood monitoring and disaster ...

Extensible Hook System for Rendezvous and Docking of a CubeSat Swarm

Engineering Proceedings
Deployment of CubeSat swarms is proposed for various missions necessitating cooperative interactions among satellites. Commonly, the cube swarm requires formation flight and even rendezvous and docking, which are very challenging tasks since they require

Comparative Analysis of Ion and Electron Contributions to Ionospheric Ionization at Auroral and Subauroral Latitudes

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Electron and proton precipitation into the nightside ionosphere is a key process in magnetosphere–ionosphere coupling. Although auroral electron precipitation at ∼0.1 ${\sim} 0.1$–10 keV is traditionally considered the main driver of auroral emissions, recent studies show that >30 ${ >} 30$ keV electrons and protons can significantly ...
