Regolith in Motion: Dynamic Surface Evolution After Lunar Impacts

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Multi‐temporal observations captured by the Lunar Reconnaissance Orbiter Camera provide valuable insights into contemporary surface changes. These images reveal that minor impact events (resulting in <100‐m diameter craters) significantly alter regolith structure over great distances (>1,000 crater diameters) by increasing the meter‐to ...

Revealing the Formation of the <20 MeV Inner Proton Radiation Belt at L ∼ 2 During the 10–11 May 2024 Superstorm

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract A new proton radiation belt was identified during the geomagnetic superstorm of 10–11 May 2024. To investigate its origin, we use an MHD‐test particle simulation to model solar energetic proton (SEP) trapping and the evolution of the initial trapped proton population during the storm.

Accelerated Discovery‐to‐Unveiling of High‐Performance and Affordable Ammonia Electrode Process by Human–Machine Collaboration Framework

Angewandte Chemie, Volume 138, Issue 25, 15 June 2026.
By employing dimensionally reduced reaction descriptors, a human–machine collaboration framework for efficient electrochemical nitrate reduction to NH3 electrocatalysts screening is established and drastically shorten the discovery timeframe. A new kinetic model is established in combination with a rotating ring‐disk electrode, unveiling the pivotal ...

Global Occurrence of Solitary Waves in the Martian Magnetosphere

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract This letter presents a global occurrence of bipolar solitary waves (SWs) in the Martian magnetosphere. We utilized medium‐frequency electric field measurements from October 2014 to December 2023 from the Mars Atmosphere and Volatile EvolutioN (MAVEN) spacecraft.

Unified monitoring of spacecrafts.

, 2015
Im Rahmen dieser Arbeit wird eine neue Philosophie der Überwachung von Raumfahrzeugen vorgestellt: die Vereinigung der verschiedenen Arten von Überwachungstechniken, die während der verschiedenen Entwicklungsphasen eines Raumfahrzeuges verwendet werden. Die Anforderungen an dieses Monitoring Framework sind: - "Separation of Concerns" als Designprinzip,
