Abstract This study investigates the sensitivity of the thermosphere and ionosphere to variations in solar spectral irradiance. Using data from the SDO and SORCE missions collected between 2010 and 2018, we quantified the variability and uncertainty of solar spectral irradiance across wavelengths from 0.1 to 190 nm and developed a data‐driven method to

Abstract The rapid development of low‐Earth orbit (LEO) satellites brings increased attention to spacecraft collisions, space debris, orbital decay, and satellite reentry. Neutral density and associated drag force on the satellite orbits elevate space risks, significantly determined by space weather disturbances, particularly geomagnetic storms.

The Impact of the 2024 Mother's Day Storm on Aircraft Surveillance Across Europe
Abstract The Mother's day storm from 10–13 May 2024 is one of the most extreme space weather events recorded in recent decades and triggered a strong ionospheric response with various impacts on communication and navigation systems. In this study the impact on the aviation sector, and more specifically air traffic management, is investigated with ...

Active Transport of Macrocycles into Micelles Using Molecular Pumps
Artificial molecular pumps attached to polymeric micelles were found capable of transporting charged macrocycles into the micelles. The pumps operate with only modestly reduced pumping efficiency as compared to nonmicellar counterparts, indicating that ring‐threading molecular pumps can transport charged solutes into supramolecular assemblies, akin to ...

Positive Feedback Between Hydrodynamics and Geomorphology Drive Regime Shift in Tidal Flat
Abstract Tidal flats worldwide are undergoing accelerated regime shifts from accretion to erosion, undermining their natural capacity for coastal protection and threatening the sustainability of adjacent urban areas. Although the influences of climate change and reduced sediment supply on tidal flat morphodynamics are widely acknowledged, the intrinsic

Abstract On 9 October 2022, a powerful gamma ray burst (GRB), GRB221009A, caused significant changes in the electron density of the lower ionosphere, as evidenced by VLF (3–30 kHz) radio wave observations. However, GRB221009A did not yield any observable signatures at the Schumann resonances (∼8, ∼14 Hz), which are also sensitive to the lower ...

The Ionosphere of Uranus as Revealed by JWST
Abstract The first spectroscopic observations of Uranus by the James Webb Space Telescope were obtained in January 2023. Using these observations, we explored the physical properties of the planet's ionosphere through the analysis of near‐infrared H3+ ${\mathrm{H}}_{3}^{+}$ spectra.

New Li Lidar Observations and Model Simulations: A Window to Anthropogenic Signatures
Abstract We present Li lidar observations in the mesopause region above Kühlungsborn, Germany (54°N, 12°E). The lithium layer is mainly formed by meteoric ablation. But lithium has a much higher relative abundance in space debris compared with meteoroids, making it a good indicator of anthropogenic influence in the upper mesosphere.

Significant Amplification of Turbulent Energy Dissipation Through the Shock Transition at Mars
Abstract Turbulence is fundamental to energy transfer across scales in space and astrophysical plasmas. Bow shock interactions have long been hypothesized to significantly modify turbulence in planetary environments, yet the quantification of such effects and their parametric dependencies remain largely unaddressed.
